Atomic Aquatics Snorkels — Engineered for Airflow, Built to Last
A snorkel is a simple piece of equipment, but Atomic Aquatics still applied their characteristic engineering attention to getting it right. The result is a three-model lineup — the SV1, SV1 Contour, and SV2 — each with a distinct design approach and a specific use case, all sharing Atomic's commitment to quality materials and long-term durability.
At DiveCatalog.com, we carry the full Atomic Aquatics snorkel range as an authorized dealer, along with multiple colorways to coordinate with your mask and fins.
The Atomic Snorkel Range
Atomic Aquatics SV1 Snorkel — Maximum Airflow Open Design
The SV1 is Atomic's flagship open snorkel — no splash guard, no purge valve, just an optimized tube designed for maximum unrestricted airflow. The top features a conical flared opening that widens at the mouth of the tube, increasing the effective cross-section available for air intake and reducing breathing resistance during surface swimming. The SV1 is the choice for divers who prioritize easy, natural breathing feel and don't want any mechanical components that could add drag or restrict flow. Available in Clear/Black, Black/Royal Blue, Black/Yellow, Black/Silver, and Black/Red.
Atomic Aquatics SV1 Contour Snorkel — Shaped for Comfort
The SV1 Contour shares the open snorkel design philosophy of the SV1 — no splash guard, unrestricted airflow — but uses a contoured tube shape rather than the straight flared profile. The contoured design follows the natural curve of the head and jaw more closely, reducing the leverage the snorkel exerts on the mask strap and sitting more comfortably during extended surface swimming. An excellent choice for divers who find straight-tube snorkels create pressure or wobble against the side of their head. Available in Clear/Black, Black/Yellow, and Black/Red.
Atomic Aquatics SV2 Snorkel — Semi-Dry with Scupper Valve
The SV2 adds two features over the open SV1 design for divers who spend significant time on the surface or encounter chop and wave action. A semi-dry top limits splash water entry during surface swimming — not a fully dry valve, but a deflector that reduces the amount of water that enters the tube in rough conditions. A Scupper Valve in the lower section of the tube allows any water that does enter to drain out naturally without a full clearing blast, making the SV2 easier to manage in variable surface conditions. The SV2 is the better choice for open-water swimmers, snorkelers, and divers who make long surface swims before or after dives. Available in Clear/Black, Black/Royal Blue, Black/Yellow, Black/Silver, and Black/Red.

Open Snorkel vs. Semi-Dry — What's the Difference?
An open snorkel has no splash guard or purge valve at the top — air flows in and out freely, which means minimal breathing resistance but also means waves and splash can enter the tube. A semi-dry snorkel adds a deflector at the top that redirects water away from the opening without fully sealing it — it significantly reduces splash entry without completely blocking airflow. A fully dry snorkel uses a valve that seals when submerged — useful for snorkelers who dip under the surface, but adds weight and can restrict breathing feel at the surface.
For scuba divers, an open or semi-dry snorkel is almost always the right choice. The SV1 and SV1 Contour suit calm surface conditions; the SV2 suits choppier open water.

Frequently Asked Questions — Atomic Aquatics Snorkels
What is the difference between the SV1 and SV1 Contour?
Both are open snorkels with unrestricted airflow and no splash guard or purge valve. The SV1 has a straight tube with a conical flared top for maximum airflow. The SV1 Contour uses a curved tube profile that follows the head shape more closely, reducing leverage on the mask strap and feeling more comfortable during extended surface swims. Airflow performance is similar — the choice is mainly about fit preference.
Does the SV2 keep water out completely?
No — it's semi-dry, not fully dry. The splash guard deflects water away from the opening and significantly reduces how much enters in choppy conditions, but it won't prevent water entry if you submerge. The Scupper Valve in the lower tube drains any water that does enter without requiring a full clearing blast. For a fully sealed dry snorkel for freediving or frequent submersion, a different design would be needed.
Which snorkel is best for scuba diving?
For scuba divers who carry a snorkel primarily for surface safety, the SV1 is typically the best choice — it's lightweight, simple, and breathes easily. If you frequently encounter wave action during surface intervals, the SV2's semi-dry top and Scupper Valve make surface breathing more comfortable.
Can I match my snorkel color to my mask?
Yes — Atomic snorkels are available in colorways that coordinate with Atomic mask colors. Check the available colors in the product listings above.
