A skydiver wears a reserve parachute, a SCUBA diver should have a reserve breathing system. For over 35 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? Explore the wealth of information about our product, and read stories from divers who are alive because of SPARE AIR.
