A BCD’s primary function is to help a diver control his buoyancy both underwater and on the surface.
A buoyancy compensator also called a buoyancy control device, BC or a BCD is valuable scuba diving equipment containing a bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy on the surface, when needed. The buoyancy is controlled by adjusting the volume of air in the bladder. The bladder is filled with gas from the diver’s air tank or from the diver’s mouth.
Providing your own BCD means that not only you’ve known where it’s been and you’ll be the only one using it but also you won’t have to wear a BCD that’s been used multiple times by different people and it’s much nicer having your own equipment!
