I dive with an Atmos 2 (console mounted) and my Girlfriend dives with an Atmos 2 (wrist mounted). For the price it is very hard to beat the Atmos II. I have had no problems and I love the quick disconnect of the console mount. Currently I only dive air, but having the Nitrox feature will be usefull later down the road. The display, backlit, audible alarms are really nice on this computer. One of my normal Dive Buddies use a Oceanic Versa Pro (wrist mounted), which is the same as the Atmos II, but the numbers are in different locations.
The numbers on the Oceanic Versa Pro are slightly larger, and would only consider that an issue if you have any eye correction requirments.

Anyone considering a Oceanic Versa Pro may want to consider this excerpt from a review on Divernet.com:
The display is big, well-lit and easily read. The Versa Pro looks great in its brushed aluminium and thermoplastic finish. It has a removable Perspex shield to protect its screen and it has a great strap. All in all, it's a very desirable piece of kit, apart from that one exception, the clue to which lies in the Safety and Reference Manual provided alongside its instructions.
Page seven of this states: ÒThe decompression model used by an Oceanic dive computer is based on the no-decompression multi-level repetitive dive schedules successfully tested by Dr Ray Rogers and Dr Michael Powell. These tests did not include dives deeper than 90 feet (27m) or decompression (stop) dives.Ó
Decompression-stop dives are the type of dives I commonly do, and I took the Versa Pro on a series of 12 such dives (many repetitive) alongside a Cressi Archimede and a Suunto Vytec.
Only once did the Oceanic momentarily show me entering deco-mode, though the other two had me into deco-mode on nearly every dive.
Not only that, but the discrepancy between the amount of no-stop time remaining on the Oceanic Versa and the deco-stops demanded by the other two was alarming.
A diver has to rely on the deco information provided by a computer. You can never tell how close you come to getting bent. Some might say that the Suunto RGBM100 model is far too cautious. Many different computers on the market, including the Cressi, use the readily available Buhlmann ZH-L16 model.
They might all be wrong and the Oceanic right. I can't tell you.
However, I can state that there were times on dives when the Suunto and Cressi were showing the first stop at 3m while the Oceanic Versa Pro showed 45 minutes of no-stop time remaining.
On one particular 38m dive, the Suunto showed eight minutes and the Cressi five minutes of total ascent time needed, while the Versa Pro still showed 15 minutes of no-stop time remaining.
On the last notable occasion towards the end of my trip, when I still had the three computers side-by-side, I did two consecutive dives, one to 42m and the second to 32m, with only a one-hour interval. At the time I began my ascent, the Suunto showed 18 minutes and the Cressi 10 minutes of total ascent-time, while the Oceanic Versa Pro was still displaying plenty of no-stop time remaining.
So who is this computer for? Surely it's not merely for those who do short shallow dives well within normal no-deco limits?
Could it be for those vacation divers who never go past 27m and never stay in long enough really to need a computer? If you think long stops are boring and unnecessary, the Oceanic Versa Pro will suit you.
