I disagree. Changing a gas mix shouldn't be complicated. I realize with some computers it is, but that doesn't appear to be the case with the AW Ultra. Seems to be easy. If a diver shouldn't worry about Nitrox settings, then they shouldn't worry about diving with a computer. It won't do them any good if it's set wrong.In my opinion, newer or infrequent divers are probably better off not having to worry about Nitrox settings.
The problem with separate Air and Nitrox modes is what happens after you do an air dive and want to switch to Nitrox. In many computers, it won't let you do that. The longstanding workaround has been to just use Nitrox mode and set the mix to 21%.I am fine with separate Air and Nitrox modes as long as the app can be configured to default to Nitrox mode with whatever appropriate O2% and ppO2 settings for those of us who choose that.
That's how my dive computers work. I don't have separate Air/Nitrox modes. I just set the gas mix for what I'm using. If air, I set it to 21% O2, and it works just fine.
