Spare Air 3.0 cu ft Nitrox Package # 300PK-N00327910S


Nitox ready up to 40% EAN


Years back in Grand Cayman I had a deck hand change my reg between dives, he just cracked the air a bit, no more. For whatever reason I had not checked my air valve like you always should and I dove in. 2 minutes later I had no air and wished I had one of these for a few breaths to figure out the problem. That feeling is not something I wish on anyone. (Wayne, CEO)
