snorkel differences..real or imagined?

Another vote for Tusa Hyperdry. I've been using an Imprex Hyperdry ( the current version is Imprex II TUSA Imprex II Hyperdry Flex Snorkel ) for a good 15 years or so and it hasn't failed me yet. Purge never leaks, and the simple baffle at the top does a very good job of keeping water out. I like it enough that I got them for both kids and my wife when they needed snorkels

I also have a Tusa Hyperdry that still is and has been, my go-to snorkel for around 15 years. Just bought the new model for a trip to Hawaii and expect that will be my new travel snorkel.

My fave too. I can snorkel with any tube but I like the Hyperdry. And it comes in combos with my favorite mask the Tusa Imprex Hyperdry for about $50 for both on Amazon

Even the Tusa Hyperdry has some breathing resistance built into it. The Scubapro Shotgun snorkel doesn't have resistance built into the design, as the air pathway is clear. Below is a diagram explaining that concept. Here's the patent on the Shotgun Snorkel concept:

Here's a photo of me on the hoist under the HH-34 helicopter, when I was in the 304th Aerospace Rescue and Recovery Squadron (Reserve), Portland Air Base, Oregon. Note the orange top of the snorkel showing in the photo (about 1972-73 time period).
