Hi,

good luck with new gear. You could dive longer. That's good.

@Glenn Venghaus Thanks for all the input, these are all valuable comments and I’ve taken them under consideration if I not already had them in my basis of design criteria.

I understand your point of view on the rolling part and agree that I’d like my technique to be that good as well to not roll during my performance, which should be priority one by putting in a lot of training effort. But wouldn’t it be an added value that; when you’re getting close to your maximum and technique seems to fail here and there or the jet streams in a pool make you tip, that the placement of the weight – you already had to carry anyway – helps you in balancing out while gliding?

It’s just that I’m trying to optimize the placement and whilst doing so create some added value along the way.

Thanks again for your great feedback.

@Lubomir Stefanoff Good question! For me a comfortable distance is a distance that:
- I can achieve always!
- I can do 4 times in a row with 2 minutes rest in between, during this rest I don’t do a breathup and just talk with sanne, until 10 seconds before I have to go.
- doesn’t give me the mental tension a maximum performance will give me.
- at the end of the dive, which has a pre-determined end, I can decide to hang still for a moment underwater before surfacing.

Just a few examples to make my point and to give some idea. The above goes the same for Sanne, I guess.

100/115 is indeed pretty high. Try to do 2-4 times 100 with small rest of 2-3 minutes in between and see if you still are comfortable with the distance…. Let me know!

Jorg, how do you define ‘comfortable performance’? Distance that you can do very time you decide to and still feel good?
With my new Glidefin I’ve been doing one 100m dive at each training (last 6-7 sessions)- and feel fine, with air left for more (last week I made the turn and came up at 115-pb)… 100/115 is quite high, so I guess 100m is either not comfortable for me, or it’s time for a max attempt

There is another reason why you can roll a bit that is not lead or technique related. Jet squirts from the side of the pool. There are 2 in my pool and every time i pass one i tilt 20+ degrees.
The better you are perfectly neutral the more you feel the effect. Like a ball perfectly balanced on the top of the hill only needs a slight tick to roll over.

p.s. Rolling of the body should not be solved with lead but with better technique in my opinion.
Same reason why you do not fix bad mono technique with an odly shaped mono to overcompensate an error you have

Do not forget the safety aspect of being able to take off a neckweight quickly (by the safety crew in case of a blackout or in very good trained divers by them salves before a problem happens) .
Most solutions with harnases disqualify for this reason.

The leg dragging is easily solved with a thin pants. I have been doiing this for years since my legs are very negative. Then a neckweight and a thin trimming weight around the waist to balance the slightly overbuoant pants.
The discomfort issue still stands unfortunately. Too loose and dangling , too tight and discomfort. It is a difficult balance and i am already on my 10th neckweight i think. This is getting very close to how i want it.

I’ve been seeing the same problem: my legs drag and I lose glide.

I haven’t tried it yet, but my thought is to use wetsuit pants to provide some bouyancy for my legs, and weights across my back. My plan is a bicycle inner tube in a figure-8, with 4 to 5 kg across my back. haven’t tried it yet.

hey sanne this is pretty interesting. I also dislike neck weights, from limited experience, because of the feeling of restriction around the arms. I haven’t noticed the tilting effect, but how would a weight, neck weight or otherwise, produce a dampening effect? Wide or narrow distribution of the weight? Your remarks about the the body’s centre of mass makes me think that the lungs work like fulcrum on a lever; and in this sense the neck is further away than the shoulders, requiring less weight to correct the body than a weight on the shoulders or back, but more than a weight than on the head or arms – assuming the body remains as stiff as a lever which of course it doesn’t and can’t and thus lies the problem. I remember reading about someone who made an ergonomic but non-flexible weight moulded to the back of the neck, but the disadvantage was it prevented the diver from looking up…! Anyway, to solve the problem I suggest a shoulder weight comprised of a pattern of small spheres of element 118, or perhaps lead , ‘sewn’ into a flexible, stretchy, but non-buoyant garment worn around the neck, head and shoulders.
