Hey, not to rain on your parade, but I'm leery of the transmitters that come with htese types of computers. I love dive gadgets - and the premise sounds great - a wireless 3-mixture nitrox-capable little wrist 'puter.
So if you use this thing wirelessly, is it easily switchable manually without the transmitters? My wife has an earlier Oceanic computer that she can never remember how to set the nitrox % - it's not very intuitive.
I have seen the wireless units work flawlessly, but there have been more than a few dives where someone was left sitting in the boat because their unit would not sync.
The idea of one less hose is great, but the sending units always seem to start acting up in direct proportion to the distance from the nearest repair facility.
Plus if you're doing a 3-gas nitrox dive - something like 28%, 50% and then 100%, that's three transmitters you have to trust your life to.
Absolute, unfailing reliability is pretty important to me so I put up with an HP hose.
Just a wrist-mount computer though, the Atom looks pretty cool. It's got a 152-page user manual though - that would take a week to get through.
I've bought stuff from Leisurepro, but something like this with a factory warranty that I'd want in place - this I'd get from an authorized dealer.
Now the next 10,000 posts will be from people who have each used a wireless computer for a minmum of 20,000 dives and never had a problem. Which is great for them, but the people I've seen sweating on a rolling boat trying to get their system up might not agree.
