Took the plunge on the OC1 LE/SE/Pioneer. Took it to the pool today and it performed great. I've seen complaints about it being complicated, but I don't see it. Once you learn the menu structure its simple. The manual sucks, but the Oceanic rep on SB is very responsive if you have any questions. I had concerns about whether the transmitter would function well because I situated it on the right side of my reg and the computer was on my left arm, but it worked great. Never lost signal. Nice book comes with it and the computer is very nice looking. Small enough to be a watch and I think I'll use it as such when I travel. I switched off the titanium band and will probably just keep the rubber band on it. Re the compass, I didn't buy it for that, but it seems to work fine. It's kind of crazy -- you can adjust for local declination and I'm not sure why you would ever do that when you aren't navigating against nautical charts, but whatever. Anyway, I'm pleased -- certainly at the sale price.
