The 1.7 Spare Air Package is the smallest portable air source in the world! Designed to get you to the surface in the event of an emergency, yet small enough to not even know you are wearing it!

Spare Air is the preferred choice of both professional and sport divers for a very good reason....It saves lives! Self-contained and user-refillable, it is a total redundant back-up miniature scuba system. In case of emergency, Spare Air provides you with enough air to safely get back to the surface. Even if you never use Spare Air, it's always there as your backup.
