What to Look for in a Snorkel? Snorkels allow you to peer beneath the ocean's surface without having to come up to take a breath, saving you time and energy.
Today's snorkels come in the following styles:
Purge Snorkel - These snorkels allow ease of clearing the snorkel of water. There is a one way valve at the bottom of the snorkel, so less air is used to clear it.
Semi Dry Snorkel - At the top of the snorkel, many manufacturers offer a "deflector" type device that discourages water from entering the snorkel.
Dry Snorkel - 100% dry snorkels have a self regulating valve that senses the difference in weight between air and water, so the snorkel top "shuts off" when submerged and automatically "opens up" when you surface. It is a fail safe and time tested device that allows a snorkeler or diver the benefit from never having to clear a snorkel of water when it is in use.
