And this seems to present the question: why does a nitrox capable computer even have an "air" mode?
It shouldn’t really be that hard to check and change your gas mix settings. If it is, the UI needs work. I would agree that reverting to normoxic Nitrox after a certain period isn’t necessary, and shows a lack of faith in the users. Which, to some extent, I get, but it’s not the responsibility of the computer manufacturer to babysit its customers. It’s their responsibility to make a computer that is easy to change those settings that are frequently changed.Which really sucks on a liveaboard, but better than reverting back to 79% N2 and 50% O2 like they used to. That’s the whole reason I got rid of all of my suuntos
I typically only dive Nitrox when doing 3 or more in a day. Then if I am going back to 2 dives a day I'll just use air.
However I will dive Nitrox one day then dive 2 tanks air daily for a week but have to set for Nitrox at 21% not set for air.
