Founded by Larry Williamson, Spare Air has been saving lives for many years. Williamson created the product from his near-death experience. Williamson ran out of air during one of his night dive, at around 140’ with no back-up air supply, he raced against time to reach the surface. He blacked out near the top and was lucky enough to have been plucked out of the water by the dive boat. Since then over 300,000 units have been produced and sold world-wide. Submersible System’s goal has always been to save lives and will continue with that moto. They are one of the top leaders in the industry for emergency breathing devices. Products are manufactured and made in the USA.
