About Aqua Lung Impulse 3 Flex Snorkel

The Impulse 3 is more streamlined and higher performing than its predecessors, the Impulse and Impulse 2. Since its introduction in 1989, the Impulse Snorkels have been the bestselling snorkels in the world. The Impulse snorkels feature a patented design, with a patented upper valve, a two-drain system and Aqua Lung's patented Comfo-Bite mouthpiece. The Impulse comes in Flex and Non-Flex versions. 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. An optional, smaller size Comfo-bite is available. 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.

Could be better

I had rented an Impulse 2 before on vacation and decided this one could only be better. I'm not so sure thats true, when I had used the impulse 2 I never had a problem with the snorkel getting water in or purging, but this one was a lot more difficult to use, but still did the job. If I was to buy a snorkel again, I would get an Impulse 2.


Most Liked Negative Review


Way Oversized...

This snorkel is way, way, way too big. I was constantly trying to get out of my face. It's like strapping a dumbbell to your head, to be frank. I understand the wide bore idea, but it's getting outrageous. I haven't noticed a big difference in breathing capability anyways. It's still a snorkel, and it's still not all that efficient. I should also mention that it flooded rather easily in open water during swells ranging from 3' (feet) to 6'.

Aqua Lung Impulse 3 Snorkel


from Agua Dulce, CA, US

For me, the best snorkel ever made. I guess Leisure Pro needs an overly elaborate review. Keeping it simple and to the point doesn't go over well here.


Clears like a dream


from Stevens Point, WI, US

The Aqua Lung Impulse 3 Snorkel clears with hardly any effort at all. the upper valve keeps the waves out of the snorkel. I have used an impulse snorkel for years. When my wife wanted to try snorkeling she borrowed mine and she had no problems at all.


Perfect equipment, perfect price


from Aurora, CO, US

These snorkels are absolutely the best; they clear so easily and feel so comfortable.


Excelent quality !


from Georgetown, MD, US

This snorkel is very special. Superior quality and ergonomically, perfect.


Great Snorkel at a great price


from Toney, AL, US

Bought one for my daughter and another for myself. Work great, stays dry and half the price of my local dive shop!
