Reviewer: Peter Weber  -  View all my reviews
I have used an SV2 for years and always enjoyed it. The purge valve remains pliable and seals well. Bought the SV1 for my wife to use for snorkeling in calmer water. Both snorkels have an easy to use adjustable slide that can be slipped off a mount that fits over most mask straps. It also has a very comfortable mouthpiece.

Excellent snorkel for free diving. Purge valve makes it easy to remove water from barrel with one puff. No water enters mouth. Can adjust in three directions for perfect fit. Robert, San Jose, CA.

Questions and Answers for Atomic SV1 Contour Snorkel:

  • Dale:

    Whats the difference between the SV1 and the SV2 snorkel and is the contour one preferred by more customers?

    Darrick  (Certified Scuba Instructor at

    Hello Dale, the SV1 is a contour with a open bore tube. Where as the SV2 is a semi-dry that will block some but not all of the water from going down the tube. If you have any other questions or would like to place an order please feel free to give us a call at 1.800.347.2822.

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 of the 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. 

SV1: High-Performance Design with Conical Flared Top

Every snorkel model in the SV Series includes 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. The flexible lower section drops the mouthpiece out of the way when not in use.

Atomic even designed a better snorkel keeper

Quick disconnect snorkel keeper includes 30 degree rotation.
Sliding snorkel keeper range adjuster allows for accurate placement without constant re-adjusting each dive.
Atomic Aquatics’ international and award winning styling team makes the SV1 and SV2 high performance snorkels something you would be proud to use.
