Whether you’re a newly certified diver looking for comfort and guidance or an experienced explorer chasing remote reefs and big pelagics, understanding your options is key to making the most of your time underwater. We will cover five popular types of scuba diving trips, helping you decide which one aligns best with your goals, preferences, and diving experience.

Liveaboard Dive Trips

One of the most iconic types of scuba diving trips is the liveaboard. These trips take place aboard specially designed dive vessels that function as both accommodation and transport, allowing divers to access remote sites that day boats simply can’t reach. Liveaboards are especially popular in destinations like the Red Sea, the Maldives, and Indonesia, where dive sites are spread out across vast areas.

The biggest advantage of a liveaboard is the sheer amount of diving. Most itineraries include up to four dives per day, often including night dives, with depths ranging from 30 to 100 feet (9 to 30 meters) or more, depending on certification level. This makes them ideal for divers who want to fully immerse themselves in the underwater world.

However, this intensity can be a downside for less experienced divers or those who are still building confidence. Spending several days at sea can also feel restrictive for travelers who prefer a mix of activities or time on land. Liveaboards are generally best suited to certified divers who are comfortable with repetitive diving and want to maximize their underwater time.

Resort-Based Dive Trips

In contrast, resort-based dive trips offer a more relaxed and flexible experience. Staying at a dive resort means you’ll have access to on-site dive centers, comfortable accommodations, and a range of amenities such as pools, spas, and restaurants. These trips are particularly appealing for couples, families, or mixed groups where not everyone is diving.

Resort diving typically involves two to three boat dives per day, with optional shore dives depending on the location. Depths and conditions are often tailored to a variety of experience levels, making this one of the most accessible types of scuba diving trips for beginners. The main advantage is the balance it provides between diving and relaxation.

On the other hand, experienced divers may find the schedule limiting, and the dive sites are usually closer to shore, meaning you might miss out on more remote or untouched locations. For those who value comfort, convenience, and a well-rounded vacation, resort-based trips are an excellent choice.

Luxury Dive Trips

For travelers seeking a high-end experience, luxury dive trips take things to the next level. These can include upscale liveaboards or five-star resorts that combine world-class diving with premium service, gourmet dining, and exclusive excursions. Expect features like private dive guides, spacious suites or villas, and highly personalized itineraries.

Luxury trips often visit top-tier dive destinations with exceptional visibility and abundant marine life, making them suitable for a range of experience levels. The biggest advantage is the seamless, stress-free experience, where every detail is handled for you.

However, this level of comfort comes at a significantly higher cost, which may not suit every budget. Additionally, some divers may feel that the structured nature of luxury travel limits spontaneity or adventure. Still, for those celebrating a special occasion or simply wanting to combine diving with indulgence, this is one of the most rewarding types of scuba diving trips.

Day Boat Dive Trips

Day boat dive trips are a popular option for travelers who want to include diving as part of a broader vacation, or those who want to book trips closer to home. These trips typically depart from coastal towns and head out to nearby dive sites for one or two dives before returning to shore, allowing for a flexible and customizable schedule.

This format is widely available in destinations like Florida, Hawaii, and across the Caribbean, and it caters to a wide range of skill levels. Shallow reef dives at 30 to 60 feet (9 to 18 meters) are common, making them suitable for beginners, while deeper or more challenging sites may be available for advanced divers.

The main advantage is flexibility, as you can choose how often you dive and what else you do with your time. The downside is that travel time to and from dive sites can reduce your overall dive time, and you won’t have access to the same remote locations as on a liveaboard. Even so, day boat diving remains one of the most versatile types of scuba diving trips.

Adventure and Expedition Dive Trips

For experienced divers looking for something beyond the ordinary, adventure or expedition-style dive trips offer a unique and often thrilling experience. These trips are typically centered around specific goals, such as exploring wrecks, diving in caves, or encountering large marine species like sharks or manta rays.

Destinations for expedition diving can include remote islands, polar regions, or areas with more challenging conditions, such as strong currents or colder water temperatures, sometimes ranging from 50 to 68°F (10 to 20°C). These trips usually require advanced certifications and a high level of comfort in the water. The reward is access to extraordinary dive sites that few others experience, often with fewer crowds and a stronger sense of exploration.

However, they can be physically demanding and logistically complex, making them less suitable for beginners or those seeking a more relaxed vacation. For the right diver, this is one of the most exciting types of scuba diving trips available.

Finding the Right Fit for You

Choosing between the different types of scuba diving trips ultimately comes down to your personal preferences, experience level, and what you want to get out of your dive vacation. If your priority is maximizing dive time and reaching remote sites, a liveaboard may be the perfect fit.

If you prefer comfort and flexibility, a resort-based or day boat trip might suit you better. Luxury trips provide a premium experience, while expedition-style adventures cater to those seeking challenge and discovery.

While the two events served very different audiences, the conversations happening on the show floor often overlapped. FDIC focused broadly on fire and rescue professionals, while the MPSDA conference brought together dive teams and underwater recovery specialists from across the region. But whether we were speaking with firefighters, marine units, search-and-rescue teams, or public safety divers, the same themes kept surfacing. 

Together with Adorama Business Solutions’ Director of Pro Services, James Bushey, I spent much of both events speaking with agencies about the challenges they’re facing heading into the busy summer season, from procurement bottlenecks to the growing need for technology that reduces risk to rescuers in the field. 

Here are some of the biggest trends we saw across public safety agencies right now: 

#1: Faster Procurement Is Becoming More Critical 

One of the most common frustrations we heard from agencies had very little to do with the gear itself. It was about the purchasing process. 

For years, procurement in the scuba and public safety space has often been slow and fragmented. Agencies typically had to call or email for quotes, wait for manufacturers to confirm pricing and availability, and then go back and forth before placing an order. Depending on the item, that process could take weeks. 

This demand for a more streamlined and efficient experience is one of the reasons we recently launched Scuba.com Solutions, a dedicated business purchasing portal designed specifically for government agencies, public safety teams, enterprise organizations, and educational institutions.  

“In fact, at FDIC and MPSDA, the launch of the new Scuba.com Solutions portal became one of the biggest conversation points at our booth.” 

Agencies were especially interested in how our business portal simplifies and accelerates procurement, eliminating many of the delays that have traditionally plagued the public safety purchasing process. 

Streamlining the Purchasing Experience

The platform gives agencies access to: 

• Customized business pricing  
• Tax-exempt purchasing  
• Accurate ETAs and inventory visibility  
• Purchase order support  
• Net 30 payment terms  
• Dedicated account management  

Instead of waiting several days for pricing or manually processing paperwork, agencies can now access much of that functionality directly online through a free business account.  

Agencies can simply register for a free business account, log in, and gain immediate access to dedicated pricing, accurate ETAs, and streamlined online purchasing. Orders can be placed using a government P-card, standard credit card, or purchase order with Net 30 terms, making the process significantly faster and more flexible than traditional procurement methods. 

That efficiency is further strengthened through our contract with NPPGov. Teams can handle smaller day-to-day purchases directly through the portal while also using the contract vehicle for larger-scale agency orders. Instead of navigating multiple vendors or lengthy quote processes, agencies can submit a request through the contract and typically receive approved pricing within just a day or two. 

The launch also builds on the infrastructure already established by Adorama Business Solutions (ABS), which many agencies are already familiar with on the imaging and technology side. Bringing that same business-focused experience to Scuba.com allows agencies to source critical diving, rescue, and marine equipment much more efficiently. 

#2: Technology Is Reducing Risk for Rescue Teams 

Another major trend across both conferences was the continued rise of rescue technology designed to minimize human risk during operations. 

Public safety divers routinely work in hazardous environments: blackout conditions, contaminated water, swift currents, and confined spaces. Increasingly, agencies are seeking technology that enables them to gather information before sending personnel into dangerous situations. 

Remotely operated vehicles (ROVs), sonar systems, underwater drones, and aerial drones generated significant interest at both events. 

These tools let agencies search, map, or assess areas without immediately sending a diver, using thermal imaging, sonar technology, and underwater robotics to help teams locate vehicles, evidence, and victims faster while reducing unnecessary exposure for rescuers. 

One of the biggest shifts James and I noticed is that agencies are no longer viewing this technology as optional or futuristic. Many now see it as essential operational equipment. 

Just a few years ago, underwater robotics systems could cost tens of thousands of dollars, placing them far out of reach for smaller departments. Today, more affordable systems are making that technology accessible to agencies with limited budgets and staffing. 

James has spent years supporting public safety operations in the field and has seen that evolution firsthand. 

“Agencies are realizing they don’t necessarily need the most expensive solution to make a major impact,” he explained during our conversation after the shows. “Sometimes even an entry-level ROV can help teams avoid putting a diver in the water unnecessarily.” 

In one example he shared, a department using compact, lower-cost underwater drones had already completed several successful recoveries without having to deploy already limited personnel into the water. 

That accessibility is continuing to change the conversation around public safety technology.  

#3: Water Rescue Teams Are Preparing for Summer Operations 

As warmer weather approaches, agencies are also preparing for the seasonal increase in water-related incidents. 

From beaches and lakes to rivers and recreational boating areas, summer consistently sees an increase in rescue calls involving swimmers, paddleboarders, kayakers, and tourists. 

That trend was reflected heavily in purchasing conversations at both events. 

Agencies were actively sourcing: 

• Swiftwater rescue gear  
• Dry suits  
• Helmets  
• Personal flotation devices  
• Rescue rafts  
• Surface rescue equipment  
• Underwater communication systems  

For dive teams, full-face masks and underwater communication systems are critical. Systems from manufacturers like Ocean Technology Systems (OTS) remain widely used for enabling divers to communicate directly with surface teams in hazardous conditions. 

Unlike recreational divers, public safety divers often work in environments where visibility is nonexistent, and conditions can change in an instant Maintaining communication with surface personnel is not just helpful; it’s essential. 

#4: Education and Support Matter Just as Much as the Gear  

One of the biggest takeaways from both conferences was that agencies are not simply looking to buy products; they’re looking for guidance, education, and long-term support. 

In fact, many departments are still navigating questions around newer technologies, including: 

• What sonar system makes sense for our team? 
• What kind of drone do we actually need? 
• How do we train personnel on this equipment? 
• What solution fits our budget? 

Those conversations are becoming just as important as the equipment itself. 

In addition to equipment support, Scuba.com now offers ERDI public safety diver training, helping connect agencies with instructors and certification programs that support real-world public safety operations. 

At the same time, the collaboration between Scuba.com Solutions and Adorama Business Solutions allows agencies to work across multiple categories from underwater robotics and marine gear to cameras, drones, and imaging systems, while maintaining a single point of contact throughout the purchasing process. 

That collaborative approach is especially valuable for larger-scale projects where agencies or marine outfitting companies may need equipment across multiple specialties. 

Final Takeaway: Public Safety Needs Are Evolving, and So Is the Industry 

Perhaps the biggest takeaway from this year’s trade shows is that public safety agencies are evolving quickly, and suppliers need to keep pace. 

Departments are under increasing pressure to operate efficiently, reduce risk, modernize technology, and do more with limited staffing and budgets. At the same time, the technology available to support those missions has advanced dramatically in just the last few years. 

That means continuing to listen closely to the agencies we serve and ensuring we build solutions that address the realities they face in the field. 

Whether that’s simplifying procurement, expanding rescue technology offerings, or helping teams access training and technical support, the goal remains the same: helping first responders stay prepared, protected, and mission-ready when every second matters. 

Agencies avoid lengthy bid cycles and purchase through pre-competed NPPGov contracts, dramatically shortening the path from need to acquisition. What typically takes months can now happen in a fraction of the time, with far less administrative lift along the way.

That timeline has a real-world impact, says Bill DeMars, VP of Business Development at NPPGov. We recently sat down with him and as he puts it, “crime doesn’t stop and wait for the procurement process. Whether it’s getting fire or EMS departments mission-critical equipment, outfitting a dive team or deploying drone technology, agencies don’t have the luxury of delays. They shouldn’t have to choose between speed and compliance.”

Thanks to Scuba.com’s integration with NPPGov, agencies experience a streamlined, transparent process: vetted contracts and a clear path to purchase, minimizing procurement friction. DeMars provides more detail below.

Inside the NPPGov Vetting Process

One of the biggest challenges in procurement today isn’t just process, it’s people. As DeMars explains, many municipal teams are facing what’s often called the “silver tsunami,” or a wave of retirements that’s shrinking experienced procurement staff at the exact moment purchasing demands are increasing. “Orders keep rising, but staffing remains flat,” he says. “That imbalance forces agencies to rethink procurement. If you have more work and fewer people, you need more efficient tools.”

That’s where cooperative purchasing through NPPGov comes in. By handling solicitation and vendor evaluation upfront, NPPGov reduces significant administrative burden, giving agencies a faster, more reliable path to purchase.

NPPGov contracts aren’t informal partnerships; they’re the result of a formal, publicly solicited, and competitively awarded process that mirrors what agencies would be required to do on their own.

“We consider pricing, but that’s just one factor,” says DeMars. “We also look at availability, industry reputation, contract terms, and product range. Our contracts focus on best value, not just lowest price.”

Before awarding a contract, NPPGov evaluates:

• Pricing structure 
• Overall value 
• Vendor reputation 
• Product breadth and availability 
• Terms and conditions 
• After-sales service and support 

This layered approach ensures that vendors aren’t just competitive on paper but capable of supporting agencies long after the purchase is made, thereby reducing risk, avoiding unexpected costs, and ensuring continuity.

Transparency is also built into the process.

“We can provide solicitation summaries, scoring, and even the original proposals if needed,” DeMars notes. “That gives agencies confidence that the process was done correctly and saves them from having to recreate it.”

From Vetting to Real-World Impact

For Scuba.com and ABS, being awarded an NPPGov contract is more than a checkbox; it’s validation.

It signals to customers that:

• The vendor has already undergone a rigorous procurement review. 
• The contract meets public sector compliance standards. 
• The vendor can support both the purchase and what comes after. 

That distinction matters most when agencies are sourcing specialized or mission-critical equipment.

“If I’m going down in the ocean, I don’t want the lowest bidder. I want the equipment I trust,” says DeMars. “Municipalities are no different. They need consistency, compatibility, and reliability, not just the cheapest option.”

Eliminating Friction in the Procurement Process

By leveraging pre-competed contracts, often through public agencies like the League of Oregon Cities, NPPGov eliminates the need for a full RFP process.

“Fire and EMS teams can move quickly on mission-critical equipment like thermal cameras, rugged laptops, or drone systems,” DeMars explains. “Contracts meet procurement standards, so you get speed without sacrificing compliance.”

That’s especially important as equipment becomes more complex.

“Procurement teams are being asked to source highly technical solutions: UAVs, live-streaming kits, mobile command systems,” he says. “NPPGov reduces that friction by connecting them with pre-vetted vendors like Scuba.com and Adorama who can deliver complete, ready-to-deploy solutions.”

The result is a faster, more streamlined process:

• Agencies can bypass lengthy RFQ and RFP cycles. 
• Equipment can be sourced quickly, minimizing operational delays.
• The administrative workload is significantly reduced. 

“What might take months through a traditional bid process can happen much faster through a cooperative contract,” says DeMars. “And in many cases, that time savings is critical.”

Nowhere is that more evident than in public safety.

“Crime doesn’t stop and wait for procurement,” he adds. “If agencies need equipment, they need it now.”

Built-In Compliance and Audit Protection

One of the less visible but equally important benefits of NPPGov’s vetting process is built-in compliance.

Because contracts are already competitively solicited, agencies can confidently purchase without worrying about crossing internal thresholds or triggering additional requirements later.

“The contract has already been competitively solicited,” DeMars explains. “So even if an agency’s total spend exceeds their threshold over time, they’re still covered.”

That protection becomes critical during audits.

“That documentation shows intent, that they’re using a compliant, approved contract,” he says. “It’s essentially their protection if they’re ever questioned.”

Supporting a Wide Range of Agencies

NPPGov contracts are designed to serve a broad mix of organizations, including:

• State and local government agencies 
• Public safety departments (police, fire, EMS) 
• Educational institutions 
• Federal entities (in certain cases) 

“We work across the entire SLED market: state, local, and education,” says DeMars. “And education is often overlooked, but there are a lot of applications there, from training to security to technology.”

Agencies that benefit most tend to rely on rapid access to specialized tools, such as imaging systems, communication technology, or drones for situational awareness.

Strengthening the Scuba.com and ABS Offerings

With the launch of Scuba Solutions and the continued growth of ABS, integrating NPPGov contracts into the customer experience has become a natural extension of both platforms.

What makes Scuba.com a strong partner, DeMars notes, is its specialization. “It complements Adorama’s capabilities in imaging, drones, and field technology,” he says. “Together, they’re able to support both highly specialized needs and broader equipment requirements.”

He continues: “From the agency perspective, it’s about simplicity. They don’t have to find multiple vendors or run multiple bids. It’s a one-stop shop.”

In other words, this isn’t just about selling products. It’s about delivering complete, supported solutions within a trusted procurement framework.

A Smarter Path Forward

As procurement challenges continue to evolve, the value of the partnership among NPPGov, Scuba.com, and Adorama Business Solutions will only grow.

By handling vendor vetting, contract compliance, and competitive evaluation upfront, NPPGov allows agencies to move faster and with greater confidence.

“Our goal is to make it easier for agencies to get what they need,” says DeMars. “And to do it in a way that’s compliant, efficient, and built for the long term.”

For Scuba.com, ABS, and the agencies they serve, that means more than just access to products. It means a smarter, more reliable way to procure them.

April is usually the time of year when everyone finally pauses to celebrate Earth Day and think about our amazing planet. But let’s be real… for us scuba divers, every single month is lowkey Earth Month. Turns out spending your weekends breathing underwater and just vibing next to sea turtles makes it pretty hard to not care about the environment.

That said, getting to witness all this underwater magic in real life comes with a unique responsibility. So, let’s take a collective deep breath and dive into how our everyday choices actually impact the big blue world we love so much.

The beauty we see vs. the reality we face

People call coral reefs the “rainforests of the sea” and it’s actually for a legit reason. Even though they cover less than one percent of the ocean floor, they somehow support about a quarter of all marine life.

Reefs aren’t just there to look dope on your camera roll, though. As you might know, they are vital for our survival on land because they protect coastlines from heavy storms and provide jobs for millions of people. If you want to geek out a bit more on why these ecosystems are an absolute game-changer, check out exactly why protecting them matters and how much they actually support us.

Unfortunately… it’s not all smooth sailing right now. Our reefs are facing some serious threats. Between rising ocean temps and heavy coastal development, a lot of these underwater ecosystems are struggling.

For instance, we’ve seen firsthand in the Cayman Islands just how fast things can go south when habitats get threatened by human activity. Alas, it’s a harsh reminder that this paradise is super fragile, and we definitely can’t take it for granted.

Your impact starts before you splash in

Believe it or not, being a sustainable diver starts way before you even leave your house for an Earth Day beach clean-up. Just take a second to think about the everyday stuff you use. Plastic pollution is undeniably one of the biggest crises our oceans are dealing with today. Every single year, millions of tons of plastic end up in the sea, totally wrecking the wildlife we love to dive with. The good news, however, is that you can easily be part of the solution just by tweaking a few daily habits. Such as learning about which common plastics to avoid in your daily life.

Furthermore, when it comes to the plastic you do use, make sure you know exactly how to toss it. Recycling can honestly be surprisingly tricky. Throwing the wrong items into the blue bin (…what people call “wishcycling”) can actually cause way more harm than good. So, don’t fall for the common traps; instead, brush up on your facts by reading up on common recycling myths.

On top of that, what you pack in your dive bag is a huge deal. Did you know regular sunscreen can be incredibly toxic to the reefs? Nasty chemicals like oxybenzone cause coral bleaching and literally poison young corals. Simply swapping out your lotion is a 0 effort way to protect the exact reef you’re about to explore. You can learn exactly what ingredients to look out for in our guide to reef-safe sunscreen.

Making waves under the surface

Alright, so once you finally backroll off the boat, your actions dictate the health and vibe of the dive site. Dialing in your buoyancy is hands-down the best skill you can have as an eco-friendly diver. Kicking up a sandstorm smothers delicate corals, and clumsily bumping into a reef can easily snap off a piece that took decades to grow. Because of this, staying streamlined and keeping your hands to yourself is the best way to ensure the reef stays pristine. For a quick refresher on leveling up your underwater habits, read up on some tips for being a better diver.

But hey, you don’t just have to stick to the “leave no trace” rule! You can actually leave the ocean way better than you found it. Make it a habit to safely snag rogue bits of trash or fishing line you spot during your dive. 

Seriously, if every diver picked up just one piece of trash per tank, the collective impact would be massive.

Be an ocean ambassador

At the end of the day, the most powerful tool you have for protecting the ocean is your voice. Think about it: most people on Earth will never, ever breathe underwater. They won’t get to see a manta ray effortlessly glide past them or watch a tiny clownfish fiercely defend its anemone. People protect what they love, and they can’t love what they don’t even know exists. Therefore, it is totally up to us to share the ocean’s story with the surface world.

Photography is a seriously amazing way to do exactly that. A single killer shot of marine life, or even a gritty picture showing the harsh reality of ocean pollution, can inspire hundreds of people. And no, you don’t need to be a pro with a massive camera rig to make an impact. But if you want some major inspiration, definitely look into some marine conservation photography to see what’s possible. Sharing your underwater memories and stories with friends and family helps build a global community that actually cares about the sea.

Let’s make every dive count

As Earth Day rolls around on April 22 this year, let’s challenge ourselves to step up our game. Let’s double-check our sunscreen labels, officially ditch the single-use plastics, perfect our buoyancy, and grab any stray trash we see on the reef.

The ocean gives us so much peace and adventure. It’s about time we make sure every single dive gives a little something back.

A passionate instructor, explorer, and ocean advocate, Laura has been working to make freediving more accessible in Scotland while showcasing the beauty and potential of its often-overlooked waters with her retreats. From training for depth in remote lochs to teaching new divers, she is playing a key role in building an inclusive and thriving scene. 

Laura tells us what it’s really like to freedive in Scotland, especially as a woman in the industry.

Diving the Cold Waters of Scotland, According to Laura McGuire

For Laura McGuire, the appeal of Scotland is its unlimited supply of depth. While it may be dark and cold, the deep waters make it the perfect stomping ground for freediving, an environment she actually really enjoys. She notes that the cold becomes manageable once she gets used to the excessive amounts of neoprene required (including a 7mm suit, hood, gloves, and socks) and the heavy lead needed to compensate for the buoyancy.

Laura and her friend Hannah Wright, the only other female freediving instructor in Scotland, frequently do their depth training in various Scottish lochs. With some reaching depths of up to 200m (656ft), the lochs provide a perfect training environment. Laura does dive shallower in Scotland than she does in the tropics; because the water is too cold for just a nose clip, she has to wear a mask, which makes equalization a bit more challenging. Despite this, she is still diving to impressive depths of 40m (131ft) in the lochs.

She also teaches in a disused quarry, which she considers an ideal dive spot. The visibility is a striking blue in the top 20m (66ft) before becoming progressively murkier as the thermoclines begin. Laura finds that she always leaves the Scottish waters with a profound sense of calm and clarity, even more so than in warmer tropical waters, experiencing an invigoration that lasts for hours. Beyond freediving, she spends her time snorkeling in the kelp forests and foraging for shellfish, primarily scallops. Ultimately, Laura believes there is an entire undiscovered world of biodiversity in Scotland just waiting to be explored.

Laura McGuire’s Scotland Dive Prep

When diving around Scotland, Laura believes that having a robust emergency action plan is key, especially since sea lochs can be extremely tidal and easily catch divers off guard. Because wrestling in and out of a 7mm wetsuit is always a bit of a “palava,” she considers a dry changing robe an absolutely vital piece of kit to help her warm up. Her tried-and-true post-dive routine often involves pouring a flask of hot water directly into her wetsuit for an immediate burst of heat, followed by a hot water bottle on her body for the drive home and a well-earned sugary snack.

Laura McGuire on the Scottish Freediving Community

When Laura first moved back to Scotland in 2022 after living overseas for eight years, she found the small local freediving community to be quite exclusive and closed off. At the time, there was no working instructor based in Scotland, and the club sessions at the pool were strictly invite-only. Over the last three years, she has dedicated herself to changing this dynamic.

Today, Laura teaches an average of 50 new Scottish freedivers every year, matching the efforts of her colleague Hannah Wright at Selkie Freediving. Thanks to their work, numerous satellite training groups have emerged across the country. Looking ahead, Laura’s goal is to run a pool freediving competition as a way to unite all the different clubs and groups nationwide. Her ultimate dream is the creation of an independent Scottish AIDA, which would allow local athletes to compete for and achieve their own national records.

Laura McGuire as a Woman Paving the Way for Freediving in Scotland

Navigating the diving industry as a woman, Laura has found that she constantly has to prove herself above and beyond. While she notes that the freediving world feels more progressive than the scuba industry, her early days teaching in Scotland came with challenges. She experienced animosity from a much older, Manchester-based male instructor who had been teaching courses in Scotland for years and felt highly territorial.

Additionally, Laura actively avoids the predominantly male Scottish spearfishing community, noting that their group chats are often driven by ego and promote unsafe practices. Despite these hurdles, she remains deeply optimistic about the future. Laura firmly believes that the sport is growing exponentially and that there are plenty of students to go around. For her, the focus should be on mutual support among instructors to cultivate a passionate and inclusive community.

Laura McGuire’s Final Thoughts

Ultimately, Laura has a profound love for the growing Scottish freediving community. She believes it is something truly worth celebrating; with its vast coastlines and rugged scenery, Scotland might seem like an unlikely destination for freediving. Yet, for Laura, the magic is undeniable. On perfect bluebird days — with golden eagles soaring overhead, mountains framing the horizon, and crisp, clear, cold water waiting below — there is simply nowhere else in the world she would rather dive.

Rewild & Free Expedition

Mara Adventures hosts retreats for those eager to experience Scottish freediving in all its glory. If you’re free this September and fancy a trip of a lifetime, check out their Rewild & Free trip; Described as “a celebration of the Scottish ocean”, a mix of freediving, snorkeling, and wild swimming. You will sail from Pontoon Marina in Oban and embark upon an unforgettable ocean adventure along the wild and beautiful West Coast of Scotland. Aboard the tall ship Lady of Avenel, you’ll spend six nights living at sea, exploring remote anchorages and dramatic coastal landscapes that can only be reached by boat. With an experienced skipper and crew guiding the journey, guests can take part in sailing the vessel or simply relax and soak up life on the water.

This expedition blends adventure, connection, and ocean exploration. Expect daily yoga and breathwork sessions, freediving or snorkelling in Scotland’s clear, biodiverse waters, and the chance to swim, paddleboard, hike, or even try mermaiding. Both experienced freedivers and beginners are welcome, with the option to complete a Level 1 freediving course on board.

That breakthrough sparked a passion that would shape the next chapter of her life. It took her to the World Championships where she represented Team GB last year. From training trips and international travel to teaching students of her own, Becky’s path in freediving has been transformative. We reached out to Becky to ask more about her journey so far, and find out about what’s coming next.

How Becky Zak Got Into Freediving and Being an Instructor

Four years ago, Becky visited Quintana Roo, Mexico, and immediately fell in love with swimming through the famous cenotes. She dived as deep as her ears would allow. Intrigued by the mysterious long fins of a freediver she met, she decided to give the sport a try. While she loved it right away, she struggled heavily with equalization (EQ). Undeterred by a failed SSI 1 course, she turned to a coach and YouTube tutorials to master the Frenzel technique. Once she finally cracked it, she was completely hooked.

She went on to complete her SSI 2 certification and squeezed in training whenever possible. After moving to Texas, she spent her summer weekends diving in Lake Travis. She even managed to shoe-horn freediving into her normal vacations abroad. Following a couple of years of independent, “rogue” diving, she decided she needed more formal direction and traveled to Dominica to cross over to AIDA 4.

Becoming an instructor was never her original plan. When organizing a trip to Bonaire, her goal was simply to book some depth sessions. However, realizing an instructor course cost about the same, she made a last-minute decision to just go for it.

The course was intense, challenging, and deeply inspiring. Armed with her new certification, she returned home to Austin, bought student equipment, and leaned on her professional background in social media marketing and video production to create her own promotional materials. She started teaching on weekends whenever she could, and has found sharing her passion for the water to be incredibly rewarding.

What Becky Enjoys About the Ocean and Freediving

For Becky, being underwater feels like flying. It brings her a profound sense of calm and freedom, allowing her to enter a world few get to experience. She loves freediving for its incredible community, the deep connection to nature, and the opportunities to travel. Beyond that, the discipline and self-awareness she’s cultivated — especially learning how to control her reactions to stress and discomfort — have seamlessly translated into her everyday life.

Becky’s Competitions and Achievements in 2025

The year 2025 proved to be unexpectedly busy. Encouraged by her British freediving friends to push past her imposter syndrome, Becky entered competitions she didn’t entirely feel ready for. Working alongside her incredible coach, Sanda Delija, she finally learned how to train productively toward specific goals. Though she had only started taking longer training trips in late 2024, her rapid progression fueled her excitement.

In the spring, she competed in Dominica with Blue Element. While initially intimidated by the immensely talented divers around her, she achieved a massive milestone: hitting 70 meters in bi-fins exactly four years to the day after her first SSI class. After a year of struggling with short trips, a lack of direction, and constantly chasing personal bests, this breakthrough was incredibly validating.

Urged on once again by her friends, she joined them for the CMAS World Championship. This is a goal she had quietly dreamed of but never truly expected to reach so quickly. Having only participated in a beginner-friendly competition in Mexico prior to this, stepping onto the “scary” world stage felt like a whirlwind. Training was daunting; surrounded by the sport’s greats, Becky had to adjust to the colder waters of the Mediterranean, which was a shock to the system. At the time, she felt her competition dives were shallow, but with perspective and reassurance from her coach and fellow divers, she walked away incredibly proud of her World Championship debut.

She closed out the year with one last competition in Dominica in November. Although her training window was shorter than usual, she arrived much more comfortable and confident. The event went remarkably well, culminating in a “pinch-me” moment when she secured an overall bronze medal — an achievement she never thought possible for herself. To top off a stellar year, Becky landed a sponsorship with 2971, wrapping up 2025 decked out in the UK’s sleekest freediving gear.

How Becky Juggles a Full-Time Career, Instructing, Training and Competing

Juggling it all comes with some difficulty! Becky has to stay incredibly organized and focused — meaning no naps after competition dives, just straight to her laptop. When she is home in Austin for a few months at a time, she works remotely while training in the pool and gym, and teaching on weekends. Thanks to her knack for time management and efficiency, this routine is manageable.

She considers herself lucky to work remotely for a highly supportive company, Create Creatine. They understand that her training is essentially like hitting the gym before work, just in the water. In fact, Becky often feels more focused at work during training trips. With fewer distractions and her restless energy burned off early, she sits down at her computer ready to tackle the day.

While she still loves teaching, it has taken a back seat recently. Because she is often traveling for training and competitions during Austin’s peak lake season, she can’t prioritize instructing as much as she used to. Moving into 2026, her new goal is to pivot toward 1-on-1 coaching rather than full courses, which will be much easier to manage alongside her busy schedule.

Becky Zak’s Favorite Place to Train

When it comes to diving conditions, Becky considers Dominica 100% unbeatable. What with the added bonus of fast internet for her remote work. She also loves the vibe and amenities of Kalamata, Dahab, and Kas. Because of the favorable time zones in those locations, she is able to dive and rest before clocking in for her workday.

Becky’s Advice For Beginner Freedivers

Becky highly recommends signing up for a formal course, whether on vacation or locally, to learn the basics and vital safety protocols before investing in equipment. Ahead of the course, she suggests checking out Instagram or YouTube tutorials on equalization and breath-hold tables. She also points beginners to the “Freediving” Facebook group — a resource she relied on heavily when she first started researching gear, instructors, and travel options — and notes that tools like ChatGPT can be surprisingly helpful for newcomers today.

Becky Zak’s Diving Plans and Goals for 2026

Becky Zak kicked off 2026 with a three-week training trip to Dominica. Having mostly trained straight into competitions recently, she has thoroughly enjoyed the chance to dive without the pressure of an impending event.

Looking ahead, her calendar is packed. She plans to compete in Dominica in May, followed by the CMAS World Championship in Roatan. By late summer, she hopes to train in Kas, which would allow her to catch up with her best friend who lives nearby. She is also planning a trip to the Maldives with Allie Riley from Blue Element to finally enjoy some vibrant marine life instead of strictly line diving. If she isn’t feeling too burnt out by the end of the year, she plans to wrap up the season at the November competition in Dominica.

Make sure to follow Becky’s training journey on Instagram. We can’t wait to see what 2026 brings for her!

The question that repeatedly comes up is: How do we reduce risk while increasing operational efficiency in high-consequence environments like public safety diving?

Todd and I come at this from slightly different vantage points, his from the manufacturing and system-engineering side, mine from procurement and departmental support. But we’re in agreement on the following fundamental point: The future of fire and public safety equipment is no longer about individual components and incremental upgrades. It’s about fully integrated systems designed to protect first responders reliably under extreme and unpredictable conditions.  As we get ready for the upcoming FDIC, these concerns and solutions are top of mind.

Industry Evolution: From Equipment to Engineered Systems

Respiratory protection has always been central to the fire service. But today, its role reaches well beyond traditional SCBA operations. Departments are responding to vehicle submersions, contaminated floodwaters, ice incidents, and recovery operations in zero visibility. These are not recreational conditions; they are hazardous, liability-heavy, and unforgiving.

One of the key themes Todd highlights is the difference between assembled gear and certified systems. “In the U.S., public safety dive teams have historically mixed and matched components from various manufacturers,” he explains. “That flexibility has helped teams change over time, but it has also created gray areas in accountability and system-level validation.”

Todd goes on to explain how European dive systems are tested and certified as complete units: regulators, full-face masks, cylinders, and communications platforms are engineered to function together. That integrated approach, he adds, reduces uncertainty because performance is validated at the system level rather than just at the component level.

“As operational workloads increase and scrutiny around liability grows, we’re seeing more U.S. departments move toward fully integrated, third party-tested breathing platforms, not to eliminate flexibility, but to strengthen reliability.” 

The Three Biggest Shifts Shaping 2026

There are three major shifts we see shaping decisions about fire and public safety equipment, now and in the future.

System-Level Accountability

Departments are asking more sophisticated questions. Chiefs and procurement teams want to understand testing protocols, certification standards, and how equipment performs within an ecosystem. Public safety diving remains outside direct OSHA oversight. This means departments must take a preemptive approach to making sure their systems are robust and defensible.

Technology as Exposure Reduction

The most powerful innovations are those that prevent responders from entering danger in the first place. Drones, ROVs, and advanced sonar systems are dramatically shortening search timelines. Todd often points out that reducing a four-hour evolution to 15 minutes isn’t just about efficiency. It’s about minimizing diver exposure to contaminated, zero-visibility environments.

Integrated Communications and Data Sharing

Modern dive operations are no longer isolated underwater efforts. Surfer-to-diver communication hubs, Bluetooth-enabled systems, and heads-up sonar displays now allow topside teams to see what divers see in real time. That shared situational awareness improves coordination and decision making when conditions are at their worst.

Shifting Procurement Priorities in 2026

From my perspective, budget conversations in 2026 are focusing on three main categories. Those are respiratory upgrades, sonar and imaging systems, and drone or ROV platforms.

Environmental realities are driving this shift. Urban flooding, ice-related vehicle incidents, and contaminated waterways are becoming more common. Dive teams are operating in fuel-soaked, debris-filled environments that recreational equipment was never made to endure.

Todd emphasizes that “one of the most dangerous things responders do is breathe compressed air at depth in zero visibility. The number one risk in diving is running out of air. That reality is fueling renewed interest in lightweight surface-supplied air systems and redundant breathing platforms adapted from commercial diving, systems that provide continuous air from the surface and reduce the risk of depletion.”

Funding, of course, is still a challenge. Federal grants continue to support underwater search- and-rescue technologies, but competition is intense. That’s where my role at Scuba.com comes in, helping departments navigate contract pricing, tax-exempt purchasing, and streamlined procurement pathways so they can access critical technology without unnecessary barriers.

Fire Rescue Dive Teams: Operational Circumstances

Public safety dive teams operate in some of the most hazardous conditions in the fire service. Zero visibility alone changes everything. Add contamination, entanglement risks, vehicle extrication, and physiological stress, and the margin for error becomes razor thin.

According to Todd, public safety diving is the “white elephant” in U.S. regulation. “It’s highly specialized, high-risk, but without a unified national standard. That gap makes equipment selection even more critical,” he explains.

Today’s expectations are shifting toward full-face masks, hardened regulators, contamination-resistant materials, and redundant air systems able to withstand prolonged exposure to gasoline, oil, and polluted water. Dive teams are no longer looking for incremental improvements. They’re looking for durability, survivability, and defensibility.

Imaging, Sonar & Search Technology

Search technology is advancing rapidly, so much so that we see it fundamentally changing underwater operations.

For example, diver-worn sonar integrated into full-face masks now allows surface teams to view live sonar and camera feeds. In some systems, topside operators can transmit diagrams or instructions directly to the diver. That level of coordination shortens search times and improves accuracy.

In many scenarios, ROVs or drones are deployed before a diver enters the water. If technology can locate a vehicle or confirm an area is clear, diver exposure decreases significantly.

But integration is key. “Sonar, communications, and breathing systems must work together seamlessly,” Todd point s out. “Departments should think beyond individual purchases and evaluate how each system connects operationally and electronically.”

Looking Ahead to FDIC 2026

From all of this we can conclude that water response today is a full-spectrum challenge that includes flood operations, ice rescue, vehicle recovery, and contamination mitigation. As we prepare for FDIC 2026, the innovations worth watching aren’t just the most advanced; they’re the most practical in reducing human exposure while improving coordination and system reliability.

That means certified, fully integrated breathing systems; lightweight surface-supplied air platforms; real-time sonar visualization; cross-platform communication hubs; and drone-to-dive coordination.

Todd and I share the same underlying belief: technology should extend capability while shrinking risk.

Whether on the show floor or in a department’s gear locker, the goal remains simple and universal. Equip responders with systems that protect them in the harshest conditions possible, so they can complete the mission and return home safely.

This is the lens we will be bringing to FDIC this year. It is not just about what’s new, but what truly moves the needle on safety, accountability, and operational efficiency for the public safety teams we serve.

Purchasing at FDIC and Beyond

If you do make it to FDIC this year, it’s important to note that support doesn’t end at the Scuba.com booth. Public safety teams can purchase equipment directly on site, but just as importantly, they can connect with me, an account manager, or a member of the product support team to get detailed information, explore what’s new, and better understand how to navigate purchasing through Scuba.com.

FAQs: Dive Bags

What is Charles’ Law?

Charles’ Law, named after the French scientist Jacques Charles, describes the relationship between volume and temperature of a gas, assuming pressure remains constant.

In simple terms:

“The volume of a gas is directly proportional to its absolute temperature (in Kelvin) if the pressure is constant.”

Mathematically, Charles’ Law can be written as:

V1T1=V2T2\frac{V_1}{T_1} = \frac{V_2}{T_2}T1​V1​​=T2​V2​​

Where:

• V1V_1V1​ = initial volume of gas
• T1T_1T1​ = initial temperature (in Kelvin)
• V2V_2V2​ = final volume of gas
• T2T_2T2​ = final temperature (in Kelvin)

This means that as the temperature of a gas increases, its volume increases, and as the temperature decreases, the volume decreases — provided the pressure remains constant.

Understanding Charles’ Law in Everyday Life

Before diving underwater, it helps to understand the principle above water. Some common examples include:

1. Hot air balloons – When the air inside the balloon is heated, its volume increases, making the balloon rise.
2. Inflating a balloon in cold vs. warm weather – A balloon expands when heated and contracts in cold weather.
3. Car tires – Tire pressure and volume change with temperature, which is why checking tires on a hot or cold day can give different readings.

These examples demonstrate how gas volume responds to temperature—a principle that applies underwater too.

Charles’ Law and Scuba Diving

In scuba diving, this law is especially relevant in gas management, buoyancy control, and equipment considerations. Let’s break it down:

Gas Cylinder Volume

When filling a scuba tank with compressed air, the temperature of the gas affects its volume.

• Cold tank: If a tank is filled in a cold environment, the gas volume inside is slightly lower. As the tank warms to ambient temperature, the gas expands.
• Hot tank: Conversely, a hot tank may show a higher pressure on the gauge at filling, but this decreases as the tank cools.

This is why dive shops consider temperature corrections when filling tanks, ensuring divers get the correct gas volume for their planned dive.

Buoyancy Considerations

This law also explains why a BCD (Buoyancy Control Device) behaves differently with temperature changes:

• Air expands when warmed, so if you inflate your BCD in the sun, it may over-expand underwater as the water cools, affecting buoyancy.
• Conversely, if you inflate your BCD in cold water, it may compress slightly, giving less lift than expected.

Understanding this helps divers adjust buoyancy gradually and anticipate volume changes due to temperature fluctuations.

Dry Suit Inflation

For dry suit divers, Charles’ Law is particularly important:

• When you add air to a dry suit, warming the suit (from body heat or warmer water layers) can increase the volume of air, making the suit more buoyant.
• If you ascend to colder water layers, the air contracts, reducing buoyancy and requiring adjustment.

This temperature-volume relationship is critical for safe buoyancy management and preventing uncontrolled ascents or descents.

Temperature Effects on Dive Planning

Divers need to account for temperature when planning dives, especially in variable-depth or thermocline environments:

1. Cold water dives: The gas in your tank contracts slightly, but the difference is usually minor at typical diving depths.
2. Warm water dives: Gas expands more with increased temperature, and if tanks were filled in cooler air, this expansion can slightly increase pressure.
3. Altitude dives: At higher altitudes, air temperature and density variations affect volume and pressure calculations, and Charles’ Law is part of the equation for accurate gas planning.

By understanding these principles, divers can make more accurate adjustments to tank fills, BCD inflation, and dry suit buoyancy.

Practical Tips for Divers Using Charles’ Law

Here are some practical applications of Charles’ Law in scuba diving:

1. Check tank temperature before filling – Avoid filling tanks that are too hot or too cold without accounting for temperature correction.
2. Monitor BCD inflation in varying water temperatures – Small volume changes due to temperature can affect buoyancy; adjust slowly.
3. Expect dry suit air volume changes – Warm your dry suit gradually to avoid rapid expansion that could cause uncontrolled buoyancy.
4. Be cautious with surface-supplied air – Gases delivered from compressors on hot days may behave differently than expected underwater.
5. Plan dives with thermoclines in mind – Moving between water layers of different temperatures can slightly affect gas volume in your BCD or dry suit.

Charles’ Law vs. Boyle’s Law

It’s important to remember that Charles’ Law and Boyle’s Law complement each other, but they describe different relationships:

• Boyle’s Law – Volume vs. pressure (temperature constant)
• Charles’ Law – Volume vs. temperature (pressure constant)

Understanding both helps divers predict how gases behave under varying conditions, keeping dives safe and enjoyable.

Fun Fact: Absolute Temperature Matters

When applying Charles’ Law, always use the Kelvin scale (0 K = −273.15°C). Why? Because gas volume is proportional to absolute temperature, not the Celsius or Fahrenheit scale.

For example:

• Water temperature: 20°C → 293 K
• Water temperature: 30°C → 303 K

Even a small change of 10 K can slightly expand gas volume, which is significant for precise buoyancy adjustments in technical diving.

Safety Takeaways

Understanding Charles’ Law isn’t just theoretical — it has real-life implications:

1. Always be mindful of temperature differences between tank fill and dive conditions.
2. Make slow, controlled adjustments to BCD and dry suit inflation.
3. Remember that volume expansion and contraction affect buoyancy, not just pressure.
4. Combine knowledge of Charles’ Law with other scuba gas laws (Boyle, Dalton, Henry) for comprehensive dive planning.

By applying this law, divers gain greater control over buoyancy, safety, and overall dive experience.

Conclusion

Charles’ Law is a foundational concept in scuba diving physics, helping explain how gas volume changes with temperature. From tank fills to BCD inflation and dry suit management, this law has practical applications every diver should understand.

While temperature changes underwater may seem minor, small differences can affect buoyancy and gas behavior, especially during longer or deeper dives. By mastering Charles’ Law alongside other gas laws, divers become more confident, precise, and safe in the underwater environment.

Next time you prepare for a dive, remember: the air you breathe isn’t just oxygen — it’s a physical system obeying the laws of the universe, and Charles’ Law is one of its guiding principles.
