Product Information
The Spare Air 600PK is a 6 cu ft / 170 liter redundant mini-scuba cylinder charged to 3000 psi / 207 bar that lets a diver reach the surface safely in an out-of-air emergency. It weighs 3.4 lb. uses a balanced single stage regulator and is user-refillable in seconds from any full scuba tank.
Who it is for
The Spare Air 600PK is built as a self-contained, total redundant back-up scuba system for divers who want an emergency air source they can carry without adding bulk to their gear. It is designed to be small enough that a diver barely notices wearing it, yet it provides roughly double the air of the standard 3 cu ft Spare Air for the trip back to the surface.
