Thinking of purchasing the Oceanic Geo to get my through my DM Course & IDC this winter on Roatan, any thoughts on it's appropriateness. I found it at a good price & just wondering if I should buy.

I own a Geo and think it's a great, straightforward, inexpensive computer. I'm not sure what if anything usage during a DM & IDC training might require beyond regular use -- assuming nothing, my guess is it would be a fine choice as would a number of other computers. Here's a review I posted a while ago:

Catt99:
I recently went shopping for a computer and had three-and-one-half concerns (in no particular order): (1) wrist; (2) nitrox capable; (3) user-replaceable battery; and (3.5) low profile so I wouldn't feel I had a breadbox on my wrist during SI or while having a beer after the last of the day's dive. Within this framework, I wanted to pay as little as I needed to -- and of course I wanted to be sure I was focused on basic fundamentals such as readability at depth, manufacturer with prior dive computer products, etc. To date I've been a warm-water vacation diver and I didn't have any interest in springing for things like wireless air integration, digital compass, super-sophisticated download capabilties, etc. -- basically a simple, wearable, computer. The user-replacebale battery became one of the defining requirements in my search.

I ended up selecting the Oceainc Geo and used it for a dozen+ dives in Belize recently. Worked very well. The manual isn't the most well written, but it provides enough to familiarize oneself with the functions and display screens. Couldn't really play with the dive mode screens until a dive, but when I did on the first dive it was intuitive and easy. The display was clear and easy to read (I was in tropical waters) and the buttons easy to control (no gloves). Encountered one warning on low NDL time and the alarm warning was quieter than others' computers' warnings I had heard on the dive but loud enough to get my attention; also experienced one "fast ascent" warning and again was not overbearing but enough to attract attention. The dive log / history function was adequate after the dive (I didn't spring for the download-to-computer capabilities so have no sense of the nature of the desktop software for dive profiles). The computer's profile over-all is not much more than a sports watch.

I'll dive Monterey soon; hope I have no issues with visibility / readability of the comp (really have no expectation of same) or with operating buttons with gloves (we'll see). And I figured (and continue to figure) when making the purchase that if I ever wanted a more complex computer I'd have the Geo as a backup. So end result is that I feel it was money well-spent and would recommend it to others looking for a straightforward and very economical wrist computer based on my limited experience with it thus far.

I've since used the Geo in Monterey, CA with a drysuit (used homemade bungies as a strap) and added:

Catt99:
Today I dived in Monterey, CA in a dry suit and 5mm gloves. I was pleased to find that I had no trouble operating the buttons during my dives. The early morning dive also happened to be rather dark at times in the kelp forests (plus overcast, so not much sunlight, and not too long after sunrise, so oblique angle of sunlight) -- I had no issue at all in reading the display with a quick glance. My previous review (a number of posts up) was caveated as to these two issues given that I had only worn my GEO in warm, clear water with no gloves. I'd dispense with the caveats at this point as it was no issue for me.

So, I think you'd be happy with it even if after Roatan you end up diving colder climes. The Oceanic's algorithm is more aggressive than some other manufacturers (I believe based on others' posted experiences with it and other computers) - but you can of course make it more conservative if you desire. On a final note, if you anticipate needing a multi-gas computer in the near future, the Geo won't do it for you; it'll handle air and nitrox to 50%, but not different gases on the same dive. If that's not an issue, then I'd say it should serve you very well.

I'd be happy to come down to Roatan and fully brief you on its use and walk you through it's features over a dozen or so dives if you'll spring for my expenses :eyebrow:
