There are elements with positive buoyancy that will condition our dives. Everything that makes us ascend towards the surface has positive buoyancy. This is the reason why we have to add weight to our equipment if we want to dive.
Among those elements with positive buoyancy is the human body itself, which has a density of approximately 0.95 kg / liter and therefore floats. The best way to compensate is to distribute weight throughout our body. The diving belt is the part of the equipment that will help us to do so.
In general, a scuba belt consists of a strap to which different pieces of lead are attached (usually 1/2 kl or 2/4 lb each).
