My husband and I are going to start scuba classes in a couple of weeks, and we are looking into snorkels. We are interested in a "dry" snorkel, ie, one that seals up when you go under water. The only model we've seen so far like this is the Oceanic Ultra Dry. We are going to buy new, but trying to conserve our $.
Any reviews? Other product recs?
Thanks in advance!

Hi Chantal--
The only reference to this snorkel I could find was on the Oceanic web site -- it's apparently very new. And I can't tell from there how it's supposed to work.
However, assuming it's designed for scuba, I'm pretty confident it doesn't seal up when underwater. Somebody correct me if I'm wrong, but that would be a very
bad thing under pressure underwater... basically the whole snorkel would collapse (can you imagine what would happen to one of those caged ball-valve thingies?), not to mention some weird buoyancy issues.
Face it, your snorkel is going to flood when you're underwater. But it'll drain as soon as you surface; worst case, you might have to blow it out if you don't want to surface your face above water for some reason.
Most "ultradry"-type features are those that keep water from splashing into the top of the tube while you're using it. Everything's got a down side; I imagine any baffles would cause increased breathing resistance. There's something to be said for K.I.S.S., especially with snorkels.
I'd personally be a bit leery of a purge valve on a snorkel too... just something that can go wrong.
Plus, I'd bet this Oceanic one is pretty expensive!
For what it's worth...
