buoyancy compensation idea for freediver/spearo

[Andrew the fish]

idea is simple, have floating line attached to weight belt, and as spearo descends pulling more line into the water with him (her), line buoyancy will be progressively pulling diver up, more and more with depth. Having line buoyancy calibrated, perhaps with attached floats at regular intervals, theoretically it is possible to keep buoyancy fairly constant. What do you think, folks? I am sure someone somewhere have tried this already.

For spearfishing this sounds incredibly dangerous. Aside from being an easy way to get tanles, Why would you want to add bouyancy when youre trying to dive down? Sort of counter productve

I understand the danger of entaglement, of course the less shite is attached the safer it is. I agree with you on this one. The idea of adding buoyancy is from me progressing into spearing during winter times with thicker wetsuit. Thicker wetsuit needs more weight to compensate the suit's buoyancy. At depth, when wetsuit is squeezed and lose its buoyancy, I end up being way too heavy and drop down like rock. You won't understand if you haven't done this. Many folks would agree with me on this part. Line that attaches from the surface, many blue water spearo's using it attached to the float and then to the gun, so the line is alraedy there, it just becomes buoyancy compensation device. And line being floating type will not be lose all over, it will be pre-loaded and fairly tight with depth from all the floats attached to it. I personally think the idea is sound (genious actually), its just you ordinary mortal folks can't get the grasp of it hehe.

maybe you should dive with less weight with a thicker wetsuit?

in a 5mm, I wear 4.4 or 5 lbs and am neutral at -14m in fresh water.

Exactly what sort of "floating line" do you envisage? What diameter & material do you think would provide you with the amount of buoyancy required? A 15m pool "noodle" perhaps?
