The Atomic Aquatics Scupper Valve snorkel design is based on the same principle as the one-way Scupper Valve used in boats. If waves or splashes enter the boat, a one-way rubber flapper located on the deck near the rear of the boat opens to drain the water then quickly closes to prevent backwash.
Atomic Aquatics only designs and releases new products that we truly believe redefine a category and solve a diver need. Did something as simple as the snorkel really require new thinking? Well...yes. More and more divers were choosing to enter the water without a snorkel because the size, unwieldiness and poor performance just wasn’t worth the hassle. Yet, the use of a snorkel during a dive can help you save precious air while hanging on the anchor line waiting to descend. There are numerous situations where a dependable, high-performance snorkel is a valuable dive tool. The new Atomic Aquatics SV Series truly redefines how a snorkel works and helps divers extend their adventure.
SV Series — 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
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.
