<p>A versatile underwater breathing device which comprises, a pressurised gas reservoir or tank (21), a buoyancy bladder (72), bladder inflation control means (76), a breathing regulator (32) in communication with the gas reservoir; and a flexible adaptable carrier having straps (88, 90) for securely attaching the carrier to the back of a diver, which carrier wholly contains the buoyancy bladder and the gas reservoir. The bladder inflation control means operatively couple the buoyancy bladder to the reservoir so that the bladder may be inflated and deflated to control the buoyancy of a diver, and the breathing regulator is also coupled to the gas reservoir to permit the breathing of the contained gas by the diver. The flexible carrier is adapted to be carried on the back of a wide range of differently sized divers so allowing a single piece of equipment to be used by a variety of people.</p> |
