ABSTRACT:
An underwater breathing device used by a swimmer, fisherman, or the like. The device eliminates the need for an oxygen system and provides a float section which holds a pair of breathing tubes upright in the water. One of the tubes has a double-acting valve system which automatically closes when water pressure is applied to the float to keep water from entering the tubes and then to the swimmer's mouth.
