Emergency backup air

Spare Air is not a substitute for your primary SCUBA air supply, dive planning or training. Check pressure before every dive. If the unit is emptied underwater, refer to the manual for servicing before refilling.

Understand your available air

The current 3 cu ft diving models contain 85 liters of air; the 6 cu ft models contain 170 liters. Depth, breathing rate, exertion and stress affect duration. No fixed number of minutes or ascent depth applies to every diver.
