Do you folks that have the Geo2 find it easy to read underwater?
I have an Atom, which I believe is basically the same, but with AI. I wear reading glasses and I have gauge reader lenses in my masks. BEFORE I got gauge reader lenses, I could read the Atom display just fine for the actual data (i.e. depth, NDL, tank pressure, etc.) - presuming we're talking about dives in reasonably clear water. In the local quarry with a stirred-up bottom and 1' of visibility, not so much. But, it was hard for me to make out the little labels that tell you what each piece of data is. That didn't really bother me, as I knew which number was which anyway, without needing to read the labels.
I did not find the Atom hard to learn at all. The buttons are basically Up and Down on the left side, Menu/Select on the top right and Backlight on the bottom right. I never felt any need for an online class.
I expect the Geo2 would be pretty much the same in all respects.
I suspect Garmin will be disappointed in sales and will cut back that development budget but I could be wrong. It just doesn't seem like a huge market.
My impression is that most everything about the Descent, except for the pressure transducer and some of the software is pretty much the same as their Fenix line. It doesn't seem like it will be that expensive for them to keep it going. The big question mark is AI. If they put out their own transmitter, then I think they'll fail before long. I think that will represent a much bigger investment and will increase sales very little. But, if they add the capability to use the PPS transmitter, then I think their sales will increase quite a bit. If they did that, I would buy one. A Descent with PPS AI would be the realization of the dream I had when I bought my Seabear H3. A watch-sized (reasonably close) computer that is very readable in low viz, supports multiple gases and trimix, and uses Buhlmann w/Gradient Factors. My ideal companion to my Perdix.
If that were available, I would dive that plus my Seabear for recreational dives and Descent plus Perdix for tech dives. I would appreciate the redundant tank pressure display on tech dives. On rec dives, I would prioritize having the smaller, more low-profile (i.e. not a brick on my arm) computers.
Plus, I would always rather have 2 totally different computers running the same algorithm, particularly on tech dives. Shearwater is awesome, but EVERYONE makes a mistake every now and then and you only have to look at Shearwater firmware Release Notes to see that even they do make mistakes every now and then. Having 2 identical Shearwaters means that if there is a firmware bug, you have it in both your computers. With 2 totally different computers, there is at least a chance that a bug in one will not exist in the other.
