Well I got it yesterday...
The software is really nice, you can download it for free and check it out.. it comes with a couple "sample" dives built in. The device works exactly as stated... the memory dump takes about 20-30 seconds. The dives are automatically logged with date and time, it displays surface intervals, and calculates SAC if you give beginning and ending tank pressure. It also gives you all the raw data from the device and it's available to copy and import into excel. Each dive also has an extra info page that lets you put down buddy, location, etc. The website also has a developer's guide so you can program your own software if you like.
It looks and works exactly as expected. The dive module is extremely solid and looks pretty indesctructable. It has exposed metal contacts, but they're big and round and shouldn't be a problem as long as it's rinsed regularly. They're really large so they can always be filed down a bit to remove oxidation, too.
It's entirely nifty.. and apparently it was pressure tested for integrity, as it has a pair of 270 foot 8 hour dives in 79 degree water already on it...
