The Atomic SV1 Snorkel features the latest snorkel technology. SV, which stands for Scupper Valve, is a small watertight tube located inside the snorkel body. The purpose of this feature is to keep the breathing airway free and clear of water. This works by allowing water to drain into a lower reservoir each time you exhale, and results in easier clearing without being uncomfortable to use.
Atomic Aquatics SV1 Snorkel – How It Works
Just like the one-way Scupper Valve on a boat, the lower section of both the SV1 enables water to be easily expelled. An internal tube located inside the main snorkel body contains a small one-way Scupper flap valve designed to allow water to flow past the mouthpiece and out the purge valve without collecting at the bottom of the breathing passage. The diver simply exhales a small burst of air to clear any water trapped below the mouthpiece, and the internal tube airway is kept dry.
Every snorkel model in the SV Series utilizes the Scupper Valve on the bottom mouthpiece section. Then, Atomic gives divers a choice of tops to best suit their needs. The SV1 design has a conical flared top to deliver maximum airflow. The SV1 is the optimal choice for calm waters or for strong swimming situations. Even though water may enter the open top, the internal tube airway remains dry. Any water trapped below the mouthpiece is easily cleared with a small burst of exhaled air.
