A diving-tank-pocket buoyancy compensator has an expandable diving-tank pocket ( 1 ) that envelopes a diving tank ( 2 ) which the diving-tank pocket is articulated for containing in addition to at least an inflated buoyancy air cell ( 3 ). The buoyancy air cell is in fluid communication with a cell end ( 4 ) of a buoyancy compensator (BC) tube ( 5 ) which has a tank end ( 6 ) in fluid communication with an inside periphery of the diving tank through a regulator tube ( 35 ) and a regulator valve ( 7 ) on the diving tank. An adjustable pressure valve ( 8,38 ) intermediate the tank end and the cell end of the BC tube is provided to maintain a pre-determined pressure and resulting constant volume of air in the buoyancy air cell for maintaining a desired constant buoyancy.
