Definition:
A Buoyancy Control Device (or BCD for short) is the jacket that scuba divers wear. It serves a few basic functions:
- It contains an inflatable bladder which you can add or subtract air from, allowing you to change your buoyancy in the water.
- The dive cylinder is attached to the back of the BCD using a tank strap.
- It allows the diver to carry or attach all of their accessories using its inbuilt pockets and D-Rings.
