The Impulse 3 Flex scuba diving snorkel took our best-selling snorkel and improved upon it either further with a two-valve system. In the event a wave breaks over the dive snorkel, the patented, upper, annular valve directs water out before it reaches the mouthpiece. Any water that does get past the annular valve drains out the lower valve, while the reservoir located below the mouthpiece keeps breathing path clear of excess water. Featuring our patented Comfo-bite mouthpiece, it does not require the diver to clench their teeth, helping to eliminate jaw fatigue.

• Keeps Water Out The Impulse has two valves: if a wave breaks over the snorkel, the upper valve directs most of the water out before it reaches the mouthpiece. But if water does get past the first valve, it will drain out through the lower valve.
• Clears Easily In the unlikely event that you would need to clear the reservoir below the mouthpiece, all it takes is a gentle puff of breath.
• Eliminates Jaw Fatigue Our patented Comfo-Bite™ mouthpiece does not necessitate clenching your teeth, reducing fatigue, even after hours of adventure. Mouthpieces are replaceable. (Available in two mouth sizes.)
• Easily Switch to Regulator If you select the Flex model, the lower unit drops away so you can use it with a regulator.
