Aside from "minimalist" diving there must be some way of getting around wearing the expensive, uncomfortable, movement-restricting and usually mandatory BCD. I've given it a lot of thought and can't seem to conjur up the materials needed to replace one. As far as I am concerned the only use for one is to stay off the bottom and to float on the surface. Mine is always empty on the surface anyway. I'd like to find a durable and inflatable by air tank kind of sausage which can be snapped into a ring around the waist. Any ideas or suggestions (keep it clean) out there?
