ABSTRACT:
Diver's gear including a unit having front and rear panels and at least one built-in dual bladder or cell assembly which includes a cell within a cell. The diver's gear also includes a back rack to carry a tank of compressed breathing gas and at least one vacuum tank. A suitable arrangement of hoses and valves is connected to the tank of breathing gas and to the outer of the two bladder cells. Another hose and valve assembly is connected from the vacuum tank for deflation of the inner of two bladder cells. The valves may be manipulated to apply pressure and vacuum in suitable combinations to the specially constructed bladder or cell assembly to provide balanced and precisely controlled buoyancy for the diver.
