Spare Air - The life-saving mini SCUBA tank.

Submersible Systems, over 45 years of saving lives 1979 to 2019

A skydiver wears a reserve parachute, a SCUBA diver should have a reserve breathing system. For 45 years we’ve supplied divers with the smallest, most-compact redundant system available for out-of-air-emergencies. The patented SPARE AIR should be a standard piece of SCUBA diving equipment for the safety minded diver. In an out-of-air-emergency, why would you trust your life to anything else? Read stories from divers who are alive because of SPARE AIR. SpareAir.com is the official Spare Air mini SCUBA tank website for divers, snorkelers, boaters, and any short term emergency air needs.

“While diving in Aruba, I was given a newly serviced tank. Someone had used the wrong size o-ring for the valve. The result was that after a few minutes, and at 95', the O-ring blew, emptying my tank in seconds. The young lady that I was asked by the local school to supervise did not have an Octopus and was on her third dive! So I had to rely entirely upon my SPARE AIR.”

Frits A. Louw, Netherlands

“This is to inform you that your SPARE AIR has saved another one. At 12 ft. I probably could have surfaced without any breathing air but the possession of an emergency backup kept me from panic. The bottom line is that I got my investment back in a few precarious minutes. So many thanks to you and your company."

Ernie Miller, Baton Rouge, LA
