that connects to a valve inlet 94 of valve 96 scuba diver 12 can selectively control the inflation and deflation of air cell system 16 via valve 96 as is well known thus diver 12 can control his descent ascent or neutral buoyancy while under water as illustrated air cell system 16 includes an air cell 98 that is selectively inflatable air cell 98 preferably has a pair of inflatable legs 100 in fluid communication with and connected by an upper inflatable crossover portion 102 and a lower inflatable crossover portion 103 a mounting panel 104 extends between inflatable legs 100 and is designed to permit air cell 98 to be securely attached to back pack 18 mounting panel 104 is not inflatable and is sealed from air cell 98 by a perimeter seal 106 e g a heat seal or adhesive seal that extends about the perimeter of mounting panel 104 a perimeter seal 107 preferably extends about the exterior perimeter of air cell 98 thus a variety of holes can be formed through mounting panel 104 or a variety of mounting fixtures can be attached to mounting panel 104 without risk of rupturing air cell 98 mounting panel 104 could.
