Scubapro Trinidad Adult Scuba Diving 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.

Length depends on the color you choose. The Black Trinidad (item 26.070.000) measures 18.5 inches and the Clear Trinidad (item 26.070.900) measures 20 inches. Both share a 1.25 inch large-bore barrel; Scubapro lists an overall product weight of 0.328 lb. Both versions use the same flexible corrugated lower section, which drops away from the face when not needed.

Yes. The Trinidad uses an ergonomic silicone mouthpiece that Scubapro lists as replaceable, so you can swap it if it splits or hardens over time rather than retiring the whole snorkel. The mouthpiece is made from high-grade silicone for comfort during extended swims, and it sits above the angled purge valve that clears water with a short breath.

Yes. The Trinidad has an integrated whistle built into the snorkel for surface signaling, so there is no separate accessory to add or lose. It also uses a quick-connect clip that attaches to a mask strap and releases easily, so you can move it between masks.

The Trinidad Adult Snorkel is offered in two colors: Black, item 26.070.000, UPC 4048336414388, and Clear, item 26.070.900, UPC 4048336414395. Aside from color, the main difference is overall length, 18.5 inches for Black and 20 inches for Clear. Both versions share the semi-dry splashguard top, angled purge valve, flex lower section, quick-connect clip and integrated whistle.
