Is that not what Rick was saying. When you put in a fo2 you are switching to nitrox mode. I asked earlier what the differences were when a fo2 was put in as opposed to air. All my computers allow me to go to air after a nitrox dive as far as i know, I will have to recheck to verify this.

Perhaps it is again timne to reask the question, What is the difference, as far as the computer goes, in diving with air or diving with 21%? Is it only a display difference or are there other things that change???
Mine dont have any "nitrox and air modes", you set the o2 percentage and off you go and it can be set higher or lower at any point you want. It also allow gas switching during theh dive...
