Used Mares Avanti Excel Scuba Fins - White - 42-43 - 8-9 Mens Snorkel Accessories The Atomic Aquatics Scupper Valve

The Atomic Aquatics Scupper Valve snorkel design is based on the same principle as the one-way Scupper Valve used in boats

The colder it gets the more heat you lose from the head by radiation

The diver simply exhales through the nose into the mask as needed to keep equal pressure on both sides of the ear drum

The unique round shape allows the regulator to be stored in a gently rolled position
