  6. 6. The Snorkel Dry Snorkel - There is only one 100% dry snorkel on the market, the Oceanic Ultra-Dry Snorkel. It has a patented self regulating valve that senses the difference in weight between air and water, so the snorkel top &quot;shuts off&quot; when submerged and automatically &quot;opens up&quot; when you surface. It is a fail safe and time tested device that allows a diver the benefit from never having to clear a snorkel of water when it is in use. This snorkel is guaranteed to be 100% dry Semi Dry Snorkel - At the top of the snorkel, many manufacturers offer a &quot;deflector&quot; type device that discourages water from entering the snorkel. 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.
