I know neither but if you have looked this closely the only thing that will now matter is personal feel. Any chance of getting them in the pool?

Kaiviti:What about the Impulse Flex 3. I am down to choosing between the impulse and the barracuda?
SwimsWithSharks:I never thought I would have a strong opinion on snorkels but I recently was teaching a class where one of the students had purchased a Riffe snorkel. At first, I had a hard time telling if she was clearing the snorkel correctly because the snorkel clears so easily. I went ahead and picked up one up and it is the easiest clearing snorkel I have ever had. YMMV.
CrazyScuba:The Impulse 3 Flex is NOT a "DRY" snorkel. It does NOT have a valve for stopping water from entering the barrel. The Barracuda is a dry snorkel. If you're looking at Aqualung, you would have to look at the Impulse Dry Snorkel. The Impulse Dry Snorkel dry valve is larger than the one on the Barracuda and functions better. It is a larger snorkel than the Barracuda, which is much more streamlined.
If I was in rough water I'd use the Impulse 3 Dry, if in calm water I'd use the Barracuda but use a Neoprene snorkel keeper in place of the one that comes on it.
Hope this helps you decide!
Damselfish:I know Walter always states flatly a simple J is the best, I disagree. Certainly nothing wrong with a J if that's what you like, and they're cheap, but there is no best of anything for everyone and every situation.
Purge valves and deflectors are very nice if you are actually snorkeling and I don't find them any harder to breath, actually easier since you're not dealing with water. I do agree that too much bulky junk on a snorkel is a drawback for diving whether you wear it (ugh) or stow it. But there are some snorkels that have fairly small purge or deflector designs that don't get in the way but are enough to help a lot.

...and I'm willing to bet it's a rubber snorkel.Walter:I'll be happy to teach you to use a simple J.
