thank you guys for all the feed back...I love my "birick", never had a problem with it....the reason I want to change computers is to have one less hose across my chest which is the best way for me to be trimed

in_cavediver:I agree with Perrone, the backup, be it 'paper' or 'puter' is your reference for how to bailout. Its not the only word and shouldn't be treated as such. Hopefully, your either a rec diver and within limits (or very close) of your backup or a tec diver and have a clue where you are and should be to get yourself out of the water safely.
Blackwood:That didn't really answer my question about how you deal with changing paradigms.
Say you are on a somewhat deep rec dive. Your primary computer's algorithm credits you for deep stops. This computer fails mid ascent and you bail to your backup, a buhlmann model which wants to push the gradient and thus dings you for your deep stops and jumps into obligation mode. Do you listen to it and hang shallow until your drain your tank? Or do you use your "clue" and continue the dive with a reasonable profile?
If you listen to the backup, why isn't it your primary? If you continue ascending in the manner suggested by the failed primary (which I hope is an algorithm you have faith in), what's the backup for?
If don't see any redundancy if you can't simply switch seamlessly from one to the other.
Note: my question involves algorithms, and thus computers set to gauge mode aren't considered "backup computers" in my questioning.

in_cavediver:Beyond Adv Nitrox, you ought to know enough to get yourself home from your dive plan.
Many people have posted this "dings you for your deep stops" canard, but I've never been able to find a profile that does this.Blackwood:Say you are on a somewhat deep rec dive.

Blackwood:Beyond BOW you should know how to get home from your dive plan (too much to ask in the real world, I know).
My initial post was with respect to your average diver who has two conflicting computers and calls it redundancy, something I still don't understand.
