What I want, and I bet I'm not the only one

I'm a dozen years older than you with at least ten times the dives. I'm very happy with my current diving and don't anticipate any significant changes. I dive nearly entirely within recreational limits, very occasionally below 130 feet, about 1%. The vast majority of my dives are no-stop, about 5% with very light deco. Nothing is certain, but it is very unlikely that I will pursue additional training /technical diving.

That being said, even though I wouldn't need it, I'd be glad to use a computer with the capability and simply not use it. I don't need the 3 gases my current VT3 has.

Most [not diving] studies I see citing oxidative stress seem to be done on 100% O2. All I see about mild hyperoxia is it is "usually well tolerated by humans". Nonetheless, if I had a choice -- all other things being equal and all that -- between 36% O2, 63% N2 or 20% O2, 63% N2, 16% He, I'd choose the latter.

Edit: -- on dives with long SS/shallow tail end anyway. I got a bit carried away on narcosis and toxicity there and didn't think of the longer off-gassing time.

My dream computer:
Uwatec Pro Nitrox with gauge mode and no stupid start up program after change of battery.
I don't mind the oil because I don't have to worry about flooding after messing around with the battery. I don't need AI, multi gases or He, colour display, background light etc etc.
I just need a simple computer to do a simple job.
