Description Since their introduction in 1989, our Impulse line of scuba diving snorkels have been the best-selling in the world. We at aqualung believe it’s the right thing to use a snorkel when diving so you can conserve energy and air while at the surface, and we’ve designed the Impulse 2 dive snorkels with several options to keep you safe and comfortable. Features 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. Flexes to fit : The flex section allows for easy positioning and will drop away when not in use
