A buoyancy compensator (BC), also known as a buoyancy Handle system (BCD), may be the tools employed by divers to ascertain neutral buoyancy underwater and beneficial buoyancy in the floor, when wanted. The buoyancy is normally managed by adjusting the volume of gasoline in an inflatable bladder, that's crammed with ambient tension fuel through the diver's primary breathing gas cylinder by way of a lower-tension hose with the regulator initially phase, directly from a little cylinder focused on this function, or through the diver's mouth throughout the oral inflation valve.
