The Catalina 19 cubic foot compact scuba tank is engineered to maintain slightly negative buoyancy underwater...even when empty. One bonus is that you can shed a pound or two from your weightbelt or BCD pockets. Comes with a 3300 PSI rated K-valve.
Every Catalina cylinder is produced from high strength aluminum alloy 6061-T6. Available in yellow. All seamless aluminum alloy compressed gas cylinders are manufactured in accordance with U.S. Department of Transportation (DOT) 3AL and Transport Canada (TC) 3ALM requirements.
