I bought a Suunto Vyper wrist for my first computer, even before I bought my BC/Reg. About a month later, my LDS offered me a package deal on a complete setup, which included a computer; an Aeris Atmos 1, which was mounted in the console.
Another month later I did 10 dives in Hawaii with my new gear. I only used the Vyper for information and was very happy. After I got home, I decided to compare the info stored in my Vyper with that of the Atmos 1. They were nearly identical, with one exception.
I did 10 dives in Hawaii, but the Aeris only stores info for 9 dives. My first dive was dropped from the log when the 10th dive occurred. It maintained info for my last 9 dives, while the Vyper kept it all.
I was surprisingly pleased with how simple the Aeris was to use. It was easier to retrieve info from it than it was with my Vyper. If you're looking for simplicity, this is it. Leisure Pro sells them for about $175.00.
