Reviewer: DAVID V.
I used this snorkel while scuba diving. It was great. Hardly got any water in it except when I was covered by the huge waves. The water was quickly drained and it was back to dry in no time. I would recommend it to anyone looking for a snorkel to scuba dive or just snorkel.

  • Carl:

    I purchesed a Aqua Lung Impulse 3 snorkle 734425 a solid piece not with a flexeble hose. What is the diferent between the two? Which is the best fins is for snorkling? Thank you Carl

    The solid work great for snorkeling. The flex tube is designed to drop out of the way when using a scuba regulator, but can also be used for snorkeling.

  • Mark:

    I have a Aqua Lung Impulse 3 Flex. A crack developed on teh flex at just a year of owning it. Can the flex be repalced? If so, Where is the flex available?

    We do not carry replacement parts for these snorkels, you might want to contact the manufacturer to see if this something they will cover under warranty.

The Impulse Snorkel continues to be the snorkel of choice for divers all around the world. 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.

Patented Comfo-bite mouthpieces, which eliminate jaw fatigue, are replaceable and an optional, smaller size is available

Removable keeper allows easy attachment or removal of the mask.

Available for shipment to U.S. zip codes only
