Diver flotation apparatus including buoyancy compensation apparatus in the back pack over the diver's back, and including an inflatable portion connected to the diver's air supply through a diver operated valve for filling the inflatable portion to achieve buoyancy compensation. The back pack incorporates internal weights, the amount and character of which can be changed to adjust the center of gravity of the diver and equipment. This allows a diver to easily adjust and maintain an optimum buoyancy and attitude relative to the water surface.
