Yup. I bought it on Craigslist. Only had 4 dives logged on it from 2000! But it was cheap and worked for my first DC. I think it's the original Cobra and not the 2 or 3.
We all went out on the boat together, but a few of us at the start of the week did a couple AOW certification dives.. like where you go to 100 feet and crack the egg and look at the color bars and take the math test. I think it was Brad, Jonathan, Brian, Nisha, and Matt. I don't remember how many of these AOW dives we did until we all started diving together.
Given that Subsurface was written by Linus Torvalds and Dirk Hondel, there are some really messed up UI/UX things that are driving me absolutely bonkers. Maybe they're good back-end guys, but the user interface really needs help.
