I have just done my Padi OWD and love it. So am looking to buy my own mask and snorkel. Decided on the Mares X Vision, as gets loads of good reviews. But can't find much on snorkels.
Have been looking at anti splash types like the Mares Stream Dry or the Cressi Aplha 1 or 2.
Will be wanting the snorkel for diving but also snorkelling.
If the vote goes for Cressi. Then Alpha 1 or 2?
Any suggestions would be appreciated.
First, there is only one thing important about a mask. IT MUST FIT YOUR FACE. Reviews mean
nothing.
My favorite mask is a cheap, black-skirted double-lens that is extremely low volume. The reason I like it, however, is that it seals real nicely without a lot of pressure on my face. I have a ScubaPro "wide view" mask and that works acceptably for me too, but I still prefer the other one.
All other considerations are secondary. If it does not seal properly and likes to leak, you will be MISERABLE. Been there, done that, have the T-shirt and it BITES.
As for a snorkel, are you going to snorkel or dive? Seriously.
If you want one, I would buy one with a straight barrel, perhaps an anti-splash (but not "valved") top, and a bottom purge. And get one with a significant-size barrel.
Just understand one thing about snorkels - other than the "valved" type they will ALL leak LOTS of water in if you are in rough open water. Further, if you're face down you will NOT see the wave that is about to curl over the top and flood the snorkel, making it real easy to get a breath full of water instead of air. The valved ones will simply CUT OFF the air when a wave breaks over them, which is bad too, as they will not "open" again until you stop sucking, which of course is the last thing you're considering doing when you try to draw a breath against a vacuum!
In rough open water if you cannot breathe off the tank (its empty!) you are, generally, better off inflating your BC fully and using it like a raft while floating on your BACK. This takes practice, so get some in a pool if you must. Also, a steel tank helps as it provides a "keel" - an AL tank will try to flip you over as its positive and under you, which is not good.
In calm water, for snorkeling, well, snorkels are very nice. They're ok for long surface swims in calm water too. Just don't be sanguine about using them in open water under less-than-calm conditions.
