Input from the dark side .... staying within no decompression limits? If so, then I would agree that the Oceanic would be perferable to the Sunnto due to the Sunnto's conservatism. My brother-in-law uses the Atom. I use a Vytec. How he sees the data on that thing is beyond me - I'd go with the VT3 instead of the Atom. I had one of the wrist watch computers and it took me about one dive to decide it wasn't gonna fly. Throw in some light deco diving and I would opt for the Vytec. The Oceanic can only compute deco stops to 60 feet and doesn't compute deep stops at all. Better yet, I'd forget about the Vytec and go with the new Sunnto Helo2. In some informal tests run by some divers here on Scuba Board, the Helo2 set at conservatism -1 was about the same as the VT3 set in normal mode which means the "Sunnto is too conservative versus the Oceanic"arguement no longer holds water. If you ever advance to Trimix, your covered for Trimix dives down to 200 feet or so (see complete review of Sunnto Helo2 over on York Shire Divers) since the Helo2 can also handle Trimix as well as air and nitrox. I believe the two main compaints about the Vytec (i.e. conservatism and the computer unnecessarily adding deco time have been addressed in the Helo2). Mine's on the way. I realize the OP didn't mention deco diving. Just thought I'd offer up these comments as food for thought.
