Spare Air provides a totally redundant air supply back up in case of an out-of-air emergency. There's no buttons to press or knobs to turn. Just bite the mouthpiece and inhale when you need it.

With 3.0 cubic feet of air, your Spare Air pony bottle gives you approximately 57 surface breaths (actual breaths vary by individual and depth). It’s easy to refill your Spare Air from a full 3000 psi scuba tank using the refill adapter included with every unit.
