The AB-911-BCD without a nylon ring is intended for sport divers who will never go below 130 feet and will not be diving in currents or with equipment. It limits the air supply to just enough to get back to the surface.
You see it here mounted on a buoyancy compensator.

The AB-2000-BCD with the colored nylon ring (green in picture) is the new model intended for divers who may go deep or may need to breathe under stress. That may be because of returning against a current or carrying a weight such as a camera or even their buddy. It is a high performance, nitrox compatible, alternate air source and can supply more air than the diver may need. It can be used to fill lift bags and other work uses. | |
The BCD-Air Buddy will mount on any standard size quick connect hose on your buoyancy compensator.It is out of your way until you need it.
It swivels in any direction, so it is just as easy for you as your dive buddy to use.
It functions equally well upside down as right side up.
To get your supply of breathing air, just bite it gently with your teeth and feel the air flood your mouth. |
