    Abstract: An improved underwater breathing apparatus includes a net bag suspended from an interior portion of a donut-shaped float with a compressed air diving tank being supported within the bag. One or more breathing hoses may be attached to the tank, and each hose may be of a fifty foot length or more. Conventional second stage regulators are attached to the free ends of the hoses so that divers may perform shallow water dives without the necessity of carrying compressed air cylinders on their backs.
