Abstract
A diver's buoyancy compensator that allows greater design freedom in the placement of the air-containing buoyancy chambers to better suit the needs of the diver. A preferred embodiment of the invention comprises four distinct surfaces, two of which make up the two halves of a floatation chamber that provides primarily back mounted floatation and the other two of which provide the chamber for more forward front mounted floatation under the arms and over the shoulder. After the two halves of each such chamber are joined to one another, the chambers are joined to each other with interchamber passageways providing free passage of air into both bladder chambers, whereby inflation and deflation in both chambers occur substantially simultaneously through a single valve or hose which may be connected to either such chamber.
