Valved Snorkel

This elegant design is for a minimalist valved snorkel for swimming practice in a pool or ocean. It uses multiple valves for separating inhalation from expired air. The valves are overly large and cut from silicon sheet and can be assembled in minutes. The parts are glued with either E6000 or loctite superglue. Please see: https://www.instructables.com/id/3D-Printed-Snorkel/ for details on assembling and testing. This is another design from the ones listed and separates the two valves into an input valve on top and output at the mouthpiece. This allows for better protection of the opening from accidental water input. The tubing used is easily replaced CPAP tubing and held in place with E6000 The clips on the snorkel stabilizer bar can be readily adjusted for the swimmers face and preferred mask and then SuperGlue in place. You can do flip turns with this model without water intrusion and is easily cleared with blowing out. (Semi-Dry)
