DEPTH AND ASCENT CONTROL FOR SCUBA DIVING

摘要

A combined digital depth control and rate of ascent control device to be used by scuba divers. The device comprises a sealed housing (10) attachable to a buoyancy compensator so as to be submerged in the water with a diver. The housing has an inlet (11) connectable to the pressurized gas tank, an outlet (12) connected to the buoyancy compensator, a control passageway between the inlet and outlet, being automatically displaced to open the passageway upon sensing the predetermined depth.
