For the uninitiated, a Buoyancy Control Device is simply a harness/vest type thingie you wear when scuba diving. It holds your air tank and, more importantly, contains an air bladder which you manually inflate and deflate. This controls your buoyancy underwater, with your goal to be neutral - free floating, like being in outer space.

This is my BCD. I love the Cressi name but went into the store with an open mind. After trying many BCD's on, I found this one fit me the best.

It is a rear-inflation BCD, meaning the air bladder is on your back, not wrapped around you. This eliminates the 'squeeze' feeling you get from jacket-style BCD's. It also provides more lift and allows for more maneuverability underwater. It can hold up to 20 pounds of emergency-release weights, 10 pounds of non-dump-able weights, and has 2 zip out and hang down pockets for small items. Plenty of D-rings are pre-attached so you can attach a compass, underwater slate, ect. very easily.

I recommend this for all scuba divers.
