I’ve been diving with analong gauges until about a month ago, when I finally swithed to a computer. I went with the Suunto Vyper 2. It does everything I want it to plus a little more. Cool thing is, I can adjust how conservative it is based on my needs and ability. At the end of the day though, don’t come to rely on the computer too much. It can fail, just like any other electronic device. Learn your tables, and learn to use the computer as another tool. Should it fail, you should be able to safely complete your dive no matter where you are.
Good luck.
