WHAT DOES A BUOYANCY CONTROL DEVICE LOOK LIKE?

Understanding your equipment

Your buoyancy control device includes an inflator, which is used to inflate / deflate your BCD through its connection to your regulator.
It also has a so-called “slow”, more precise purge valve (also known as a dump valve), as well as 3 “quick” purge valves, including:
- one on your shoulder, to be used in a vertical position (head up): the ‘upper purge’
- the other at the base of your back, also used in a vertical position, but this time with your head down: the ‘lower purge’
- a third valve (known as a ‘Fenstop’), operated by pulling on the inflator in case of emergency.

Any of these purge valves will enable you to deflate your BCD and therefore lose buoyancy. However, it’s better to use certain ones in case of emergency. It’s also very important to be able to locate your purge valves quickly and easily while underwater.

              The buoyancy compensator or buoyancy control device, called a "BCD" in diver-speak, plays more than one role in the water: it keeps the tank on your back, helps you adjust your buoyancy, helps you to get back to the surface effortlessly and even keeps you up there. Check out our simple and practical guide that will help you choose your buoyancy compensator.

              I’m a diving equipment product engineer at Subea. I began diving as a teenager, but it was only after I started my job that I really developed a passion for it. I decided to get certified and go through the various levels of training, and now I’m a PADI Rescue diver with “Deep” certification.
