The Impulse 3 uses a two-valve system. If a wave breaks over the snorkel, the patented, upper, annular valve directs most of the water out before it even reaches the mouthpiece. Any water that does get past the annular valve drains out the lower valve The reservoir located below the mouthpiece keeps breathing path clear of excess water. In the rare event that you need to clear the Impulse 3 Snorkel, almost no breath is needed, all it takes is an easy puff
Patented Comfo-bite mouthpieces, which does not require the user to clench their teeth, eliminate jaw fatigue

Comfo-bite mouthpieces are replaceable
The flex model allows the lower unit to drop away for use with a regulator Also available in a non-flex, standard version
