Good choice. Check out the video(s) on how to use it. Did it come with a manual? If not you might be able to find a pdf. That said, you'll still probably have to watch the videos.

thx to all for the replies and suggestions...I ended up buying a slightly used Geo 2.0
I really love my Cressi Archimede II. it is very simple and large enough for me to read the digits. At +2.0 now, I won't be able to dive with modern handwatch-sized comps. The only thing I do not like is that once in the water, "Time" mode is switched off but the comp does not show any useful information. This makes timing of long surface swims when shore diving impossible. But maybe for you this does not matter.In the past I've borrowed, rented, or gone w/out a dive computer, but I plan on doing a lot more diving than I have in been (recently retired), so for many reasons clearly I need to buy a computer.
Since I don't need "the latest & greatest" in dive computer--and I'm not opposed to saving money --if possible I'd like to buy something used, preferably here on scubaboard's classifieds, though I'm open to ebay or whatever. However, since I'm not up on the different makes & models of dive computers, which have a good reputation, etc., I'm hoping I can get some suggestions from those of you w/ more knowledge & experience than myself advising me on which would be a good computer to buy, what's a fair price to pay, etc.. In exchange for your advice you'll receive my sincere thanks and a couple round of drinks if I should run into you somewhere!
Basically I just want something that's easy to use, easy to read, reliable, and durable. I don't log dives, don't download data to a computer, etc., so nothing high-tech needed. I'm open to either a wrist or console computer, I imagine there are pros & cons to both. Air integrated I assume would be a nice feature, but don't know if it'll be with the $$$ to me.
Feel free to ask questions if necessary, but "I don't know what I don't know", so I'm not sure what else I can tell you. Otherwise, thanks in advance for your advice and suggestions!
YouTube is free.
I HIGHLY recommend you pay the $7-8 or whatever it is to learn how to use your dive computer at the below link. It has many video modules that shows you what the actual screen will look like in different scenarios and even has a dive simulation. It is super helpful. I know it looks stupid but it is a really good website. You will know exactly how to set all settings in your Geo 2 and what your computer is trying to tell you on a dive. They do a lot of other models as well and I thought it was an excellent supplement to the somewhat poorly written Oceanic manual (I have a backup Veo 2.)
How convenient is a transmitter? seems like one more thing to go wrong, but I don't want to miss a good deal on a used computer with the optional transmitter.
