Atomic SV Snorkels - How they Work
Just like the one-way Scupper Valve on a boat, the lower section of both the SV1 and SV2 (semi-dry) enable water to be easily expelled. Any water entering the top of the snorkel (1) bypasses the mouthpiece completely and exits out the purge valve (4). If water did enter the internal tube (2) located inside the main snorkel body, it contains a small one-way Scupper flap valve (3) designed to allow water to flow past the mouthpiece and out the purge valve (4) 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. It’s so simple and so effective we have a patent pending!
Features and benefits of the Atomic SV Series high performance snorkels
The Scupper Valve (SV) design is self-draining and delivers crisp, effortless clearing. Posi-lock flex retainer secures flex section and mouthpiece. (1) Dual silicone mouthpiece prevents over-clenching of teeth that would restrict air flow. (2) Rotational mouthpiece with ratchet indicators. (3) SV1 has a conical flared top for high performance breathing. SV2 Semi-dry top is designed to limit splashed water from entering the breathing tube.
SV1 Flex: High-Performance Design with Conical Flared Top
| SV2 Flex: High-Performance Design with a Semi-Dry Top - The SV2 includes a Scupper Valve lower section with a sleek semi-dry top. The SV2 semi-dry top employs horizontal vents engineered to diffuse splashed water that would normally freely enter the snorkel top. The small gaps between the vanes of the vent restrict water speed and droplet size and permit most of the splashed water to exit the special vents without entering the breathing tube. The end result is less water in your snorkel. The SV2 is perfect for rough or choppy water conditions. |
