I am thrilled with my Mosquito. I have been diving it for 2-3 years as a backup to my Cobra Air-Integrated. I started 10-12 years ago with a Cochran Commander+ Nitrox as my first computer. It was great but rather bulky and the computer interface and software was really bunk compared to the Suunto. I liked the idea of air integrated but I wanted to have a backup at all times. I've got a spare SPG on my primary Reg (an ATX-200) and can easily move the Cobra to my backup in 5-10min (doing a careful job) if necessary. It works well and as there is already an SPG there, all good.
The one or two times I've had to go to my backup regulator (and ATX-100 masquerading as a Zeagle Flathead -- from the days of Zeagle whitelabelling Apecks) I actually have not bothered moving the Cobra and just dive the Mosquito.
The good thing, imho, about using these 2 same gen-Suunto computers is that the tables are the same. Should they not very closely resemble one anothers output when I check post dive, I know something weird is going on. I keep the Cobra on a retractor zipped in around my cumberbund (where I can just look down and see the LCD, rarely have to move around to see it) and the Mosquito tends to live on my wrist; there are sometimes minute differences in readings if I didn't spend the whole dive planar (who does?)
Honestly, I'm unaware of any reason to get a new or different computer (until one dies
both work really well, I'm not dead and have never seen the inside of a chamber as a patient. I wear the Mosquito as a watch on dive trips (sometimes just around town when I want waterproof or not fancy) and I always know my SI and No-Fly times, etc. On a liveaboard its really nice.
The Mosquito does tend to get caught on jackets and shirts as I'm getting dressed/changed and using as a regular watch. The rubber face protector is of dubious value. After 3 years its still on there and the face is not scratched but on several beach dives it has gotten sand caught in there and I worried enough to take it apart UW and "rinse" it. Silly, but thats Type-A me. Mosquito takes some figuring out and the manual is nice to keep around. Its not the most intuitive UI. The Cobra, you just dive with and look at. Even Nitrox/mixed gas adjustments are easy.
I really don't see the value in a flashier/metal cased dive computer/watch or a newer Cobra2/3 computer. I haven't seen a table of features I'm missing or anything...
