A scuba divers’ buoyancy compensator, which is also called a buoyancy control device, is to help them maintain neutrally buoyancy through the dive.

Other names fora BCD or Buoyancy Control Device include BC, stab jacket, buoyancy wing or ABLJ. Although I don’t think you can get an ABLJ any more as this is an old style buoyancy device.

The reason for needing a BCD is because of the density of water, which gets greater the deeper you dive.

A buoyancy Control Device has an inflatable bladder inside that is filled with air. As you descend on a dive you add more air to this air-bladder. This extra air compensates for the fact that you become less buoyancy the deeper you go. The reduced buoyancy in due to the water pressure around you.
