DiveCatalog.com Basic Black Silicone Snorkel

A classic open-top snorkel is a simple tube, the most reliable design, but it takes on water when a wave passes or you duck under. A semi-dry snorkel adds a splash guard at the top that deflects surface chop, though it still floods if fully submerged. A dry snorkel adds a float-operated valve that closes the top when submerged and keeps the tube mostly dry, at the cost of more moving parts and a little extra bulk and buoyancy.

A purge valve is a one-way valve in a sump below the mouthpiece that lets water you blow out drain away instead of sitting in the tube. It makes clearing easier, since a short sharp breath clears the snorkel with much less effort. The tradeoff is one more part that can foul with sand or grit, so rinse it and check that it seats cleanly.

Snorkels attach on the left side of the mask with a keeper that grips the mask strap, leaving your right side clear for the regulator hose. Position it so the mouthpiece reaches your mouth with the tube running alongside your head, without twisting the strap or pulling the mask skirt off its seal. Many keepers are quick-release, so you can remove the snorkel without disassembling the mask.

It depends on your training agency, the dive operation, and the diving you do, since some courses and operators require one. A snorkel lets you breathe at the surface without using tank gas, which matters on a long surface swim or in chop while waiting for the boat. Follow your instructor's or operator's requirements, and consider a folding snorkel if you want one stowed rather than on your mask.

A snorkel that is too long or too wide increases the volume of air you rebreathe and makes clearing harder, which is why recreational snorkels cluster around similar lengths and bore sizes. A flexible lower section lets the mouthpiece drop away from your face while you are breathing from the regulator. Mouthpiece comfort matters more than any other feature, so pick one you can hold without jaw fatigue.

Rinse the tube, mouthpiece, and purge valve in fresh water after each dive day, then let it drain and dry fully, because standing salt water in the sump grows mold. Check the mouthpiece for splits and the purge valve for trapped grit, both of which are inexpensive to replace. Store it out of direct sun so the silicone stays soft and clear.

No. This is a classic open-top snorkel with no purge valve and no dry valve. The tube is a plain J-shape, so you clear it with a sharp breath out and there are no moving parts that can trap sand or grit. That simplicity is the point of the design, which is why open-top snorkels remain popular for training programs and backup use.

Yes, it is built for exactly that. The simple open-top J-shaped tube and silicone mouthpiece give straightforward surface breathing with nothing to learn or adjust, which is why it works well for beginners, training programs and rental fleets. If your course or dive operator requires a specific snorkel style, confirm with your instructor before class.

It is offered in black in a single configuration, SKU DC-SNK-BASIC-BLK, so there is no size or color choice to make. The uncomplicated black design keeps it consistent if you are outfitting a class, club or rental fleet with matching gear. Call 888-701-4017 if you need help with a multi-unit order.

It attaches with a keeper that grips the mask strap, so it mounts to standard snorkeling and scuba mask straps. Most divers mount the snorkel on the left side of the mask so the right side stays clear for the regulator hose.
