We all know that compressed Air stored in the diving cylinder comprise of atmospheric gases that hold a maximum pressure rating of 3000 to 4500 psi. When we say atmospheric gases, we refer to a combination of Oxygen, Nitrogen and other inert gases that make up the earth’s atmosphere. In terms of proportion, Nitrogen accounts for around 78% of air followed by Oxygen at 21% and the remaining 1% comprise of inert gases such as Argon and Carbon Dioxide.

Non-divers are perhaps predisposed to the notion that the same proportion occurring in breathing gases is ideal for use in the conduct of scuba diving activities. While most recreational divers are geared up with an open circuit scuba set designed to be ‘Air’ compatible (out of the box), many seasoned scuba divers would prefer the use of Enriched Air Nitrox (EANx). Nitrox gases contain higher proportions of Oxygen at a maximum rate of 40% and lowered proportions for Nitrogen. For example, a mixture of EAN32 implies a combination of 32% oxygen and 68% nitrogen. Wonder why Nitrox mixtures are regarded as better suited to scuba diving than the regular Air mix? Well here’s how.

The lowered Nitrogen content in Nitrox or EANx mixtures decelerates the absorption of Nitrogen into the blood and bodily tissues to effectively extend No Decompression Limits (NDL) or No Stop Times and increase bottom times than what the regular breathing gas mixture would allow. Consequently, use of Nitrox gases in the conduct of repetitive dives will help reduce Residual Nitrogen Time (or the duration of excess Nitrogen discharge from the body) and likewise allow for shorter surface intervals between 2 consecutive dives. Now you wouldn’t experience these benefits in the use of atmospheric Air mixtures. Nonetheless, these advantages are not available without cost considerations. Whereas Air can be easily derived from the atmosphere and prepared (apart from being virtually free), Nitrox mixtures are generally expensive. Using Nitrox gases during your dive would cost you around $10 per tank and would likewise require the diver to undergo formal training to get Nitrox certified.

Neophyte divers would initially dispense with the idea of using Nitrox mixtures. But as the scuba diver advances with training and skill; with a number of certifications and open dives in his dive logbook, the intent of using more specialized scuba equipment also arises. Therefore, it would be wise to invest on Nitrox-compatible scuba equipment early on from the scuba regulator, octopus regulator and dive computer. The Aeris A1 scuba regulator is Nitrox-compatible and can handle gas mixtures of up to 40% Oxygen without requiring special preparations or maintenance. To improve your margin of safety, get a matching A1 Octopus regulator that has been configured for Nitrox use as well. Meanwhile, the Aeris XR-2 Wrist Dive Computer [http://www.scubasuppliers.com/site/1408308/product/10.2610] can be programmed to function as an Air computer and then as a Nitrox computer for mixtures of 21% to 50%.

Scuba

Everybody knows what scuba diving is; it is the diver with the air tank on his back and a mouthpiece. The basic scuba set-up is a tank of compressed oxygen on the diver’s back, with a line to a mouth piece. The oxygen is delivered through a mouth piece, allowing the diver to breath. Your carbon dioxide is then either released into the water, or, in self-contained systems or rebreathers, back into the tank. Few people actually know that scuba stands for something, however. The word ’scuba’ is actually an acronym for “Self Contained Underwater Breathing Apparatus”. Scuba diving is, of course, different from unassisted diving. The history of scuba is quite recent. The biggest advance on the path to scuba diving came in the 16th century, when people started using diving bells to pump air from the surface to people underwater. Needless to say, things have advanced a fair bit since then, although the diving bell remained an important method for centuries. Scuba diving as we know it really came together during and after World War II.

Why is scuba diving such a popular sport?

It is hard to think of a sport or hobby more exciting or rewarding than scuba diving. First off, scuba diving gives you access to underwater life in a way nothing else can. The vast majority of the world is underwater and waiting to be explored! When you scuba dive, you become one of the few people to have ever ventured into this exotic world to any degree. The world’s seas and oceans are some of the last few undiscovered places on our planet - that is why scuba diving is so awesome. There is also the fact that it can be absolutely beautiful under the water. If you have ever had the opportunity to go scuba diving off the coast of Australia along the Great Barrier Reef, you will know how amazingly gorgeous life under the sea can be. Scuba diving can even give you the chance to search for buried gold and treasure. From the Caribbean to the Mediterranean to the Great Lakes to the English Channel, there are countless shipwrecks waiting to be explored.

Risks associated with scuba diving

It should be noted that, despite being an amazing hobby or sport, scuba diving can be dangerous; after all, you are putting yourself under water and hooking your lungs up to a tube of air. If something goes wrong with your air or you become trapped, then you will experience obvious difficulties. The most common injury related to scuba diving is a result of changes in air pressure. As you go deeper underwater, the pressure around you increases. If the pressure becomes too much, you can rupture your eardrums or damage your sinuses. And if you come up from underwater too quickly, you can also get ‘the bends’, also known as decompression sickness.

How to become a scuba diver

Before getting into the water, it is important that you receive the proper certification from your national certification board to be a scuba diver. Indeed, many rental agencies will not rent you equipment without proof of certification.
