Spare Air was patented and was shown at its first trade show in 1979.  Since then over 200,000 units have been produced and sold world-wide.  The first "testimonial" letter the company received where someone saved their life with the product was February 1983.  The testimonial letters poured in over the years, with over 100 letters received so far.

Soon after the success in the dive market, Spare Air was modified and sold to the military in 1984 under the name Helicopter Emergency Egress Device (HEED) to help helicopter personnel from almost certain death in the event of a water crash. It is now used by most military and government organizations here in the US and in most developed countries around the world. Spare Air has been used in a myriad of movies such as Jaws, Waterworld, Spy Kids 2, Baywatch, The Fugitive 2, Sphere, and Perfect Storm. Spare Air is also used at aquariums around the world.
