Hey guys my friend said hes soposed to get me this buoyancy system that goes around your wast and inflates with water to make you sink and theres this small air tank that when you want to ascend inflates with air and make you go up .Anyone heard of this before .thanks
I've seen a system that attaches to your weight belt. It looks like a small parrachute bag and when the rip cord is pulled it inflates to take you to the surface.

I've never heard of one that makes you heavier, I'm not sure that would work, you would think the water in the bag would be equally bouyant with the water in the ocean. Therefor you would not sink you would just be more bulky. But there may be something I'm missing as I'm not an expert.

The diver that had one I had seen said he used it for diving around oil rigs. When he speared a fish he would swim horizontally away from the rig so the fish didn't get tangled in the structure. Then pull the ballast to start moving him vertically to the surface.

Hope that helps.
