Do I dive with a computer? Well, actually, I dive with three of them -- a Cobra (air integrated), Mosquito (primary source of depth info) and the one above my neck (te overall coordinator of what I'm doing).
Having just finished my first "DIR" (well, maybe DIR -- at the very least baby DIR) class, I was interested to hear the instructor say, NO COMPUTERS -- COMPUTERS BAD! "NO" I quickly shout -- he glared (well sort of). But he was/is exactly correct in his criticisms of the use of computers -- and, to my always humble mind, many of the replies on this thread support his belief.
As with any thing else we do in Scuba, a computer is merely a tool -- and it is as good of a tool as our understanding of it. IF you actually have not spent the time and effort to understand deco (and I have certainly NOT) then relying on the computer to keep you safe is the ultimate in trust me diving.
However, DarkP -- as much as you (and yours) say you don't "rely" on computers, I really think you do -- they just happen to stay dry -- and then you rely on the one above your neck to remember and follow the plan the dry computer provided you!
BTW, I have two primary reasons for continuing to use my Cobra:
a. I really like the close to real time "air time remaining" feature -- it saves me from doing Scuba Math and is a good cross check on how I think I'm doing; and
b. On trips to the tropics (and do I LOVE warm water) when I'm on a charter, I can answer "YES, I'm diving a computer" and they don't hassle me about bottom time.
