The Spare Air Xtreme 6 is a complete mini dive & snorkel system. Comes fully assembled, ready to strap on to your waist and jump into the water. The 6 cubic feet tank provides up to 20 minutes of air when diving less than 30 feet. Divers have been asking for a small, portable mini scuba kit but with more air than our traditional Spare Air model provides. Weighing only 5 pounds, this simple mini scuba system is ideal for shallow water diving, boat maintenance, or treasure finding.
