Its popularity is due to the highly efficient upper valve system, which guides excess water away from the main airway preventing water from reaching the mouthpiece. The Impulse 3 is an improved, more streamlined version of the original!Since Aqua Lung introduced the first patented IMPULSE snorkel in 1989, it consistently has been the best selling snorkel in the world. Today, after continued refinement and evolution, the Impulse 3 is more streamlined and produces a higher performance than its predecessors, the Impulse and Impulse 2.To provide the driest breathing snorkel possible, 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 usually 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.The unique design of the Impulse 3 snorkel, with its large bore, delivers extremely low breathing resistance while the body of the snorkel creates little drag.Available in a FLEX version that allows the patented COMFO-BITE mouthpiece to drop out of the way while switching from snorkel to SCUBA.The non-flex version has a swivel design that allows optimal mouthpiece positioning.
