A while back I did a thread about the pros and cons of diving nitrox (32%) but using an air computer. The idea was......a lot of people say they are less tired with nitrox....and using an air computer would add an additional safety margin. There was a lot of good discussion on that. (my lds hates nitrox and when I asked the question there, the owner indicated it is the only way he would recommend diving nitrox)
But, my question here is.......if one does dive nitrox in the main tank.....is it ok to still just have "air" in a pony bottle? And, when I say pony bottle I dont mean a deco stage bottle.....just a small 13 cu ft bail your butt out of a jam bottle.
Would switching to the pony in an emergency and breathing air after having breathed nitrox for a while cause any problems?
(my thought is it wouldnt....you breath "air" when you surface, but there might be something I am missing there.)
