Abstract
An underwater breathing apparatus well suited for beginning snorkelers, having a mouthpiece, a floating air pickup, and a flexible breathing tube connecting the two. The mouthpiece has a one-way inlet valve and a one-way outlet valve. Air flow is thus rendered unidirectional. Air flows in from the pickup, through the breathing tube, and then to the mouthpiece. The inlet valve prevents the breathing tube from collecting water. The outlet valve discharges spent air and collected water to the exterior. Air thus expelled simulates scuba breathing. The flexible breathing tube enables a novice to enjoy snorkeling without being obliged to hold a rigid breathing tube upright. The floating air pickup has angled, swiveling connection to the breathing tube, thus rendering the float more stable. In alternative embodiments, the breathing supply is manifolded to supply more than one user. In further alternative embodiments, the apparatus includes a hook or eyelet for retaining small personal articles on the float, and includes indicators for observers above the water level to monitor correct breathing procedure. The float is brightly colored to enable an observer to locate the apparatus at a distance.
