Snorkel lock for Oceanic Snorkels. The Snorkel is a necessary piece of diving equipment that encumbers us during most of our dive when not in use. However, Oceanic's patented swiveling Snorkel Lock allows the user an easy put-on/take-off method for their snorkel. The durable, corrosion proof and impact resistant plastic Snorkel Lock uses industrial strength hook-and-loop fastener for a strong and secure attachment.
