Is there any use buying an o2 analyzer if you strictly dive air? I never exceed 110' depth and only dive air but wondering if there is any use getting an o2 analyzer to make sure overseas dive ops are actually giving me air. Am i just being paranoid?
I'd buy a CO analyzer first. CO is a huge issue irrespective of air vs. nitrox. I would definitely use a O2 analyzer if I fill in a place that fills nitrox/O2 tanks and there is a chance that they would put in a higher O2 % mix in my tanks. If I want air, I want to make sure that it is air indeed in my tanks. Nitrox in my Tank with MOD shallower than my intended depth can be a killer.
