Standard Features

WARNING: A Buoyancy Compensator (BC) is NOT a life jacket! It is
not designed to provide face-up flotation in all situations, and it does
not meet U.S. Coast Guard regulations for a life preserver or personal
flotation device (PFD). If you become unconscious in the water without
a buddy present to immediately assist, you may suffer serious injury or
death from drowning.

used to manually inflate or deflate your BC. The power
inflation valve is connected directly to your regulator’s
first stage, and can be used to inflate your BC with the
push of a button.

the upper shoulder unit of the integrated inflator, is
connected to the lower Power Inflator by a cable located
inside the corrugated hose. This valve can be opened to
