Just want to let you know my experience, I took the IANTD course and did my (2) dives with out the instructor (stupid I know but he told me it was no big deal) and it turned out that we had bad fill with compressor oil getting into the tanks. My father and brother did (2) dives with this bad mix because they thought that it was just the "taste" nitrox (even thought we were told there was no taste) I was a little smarter with my buddy and called off the dives. If we would have had the instructor with us he would have set everyone strait about the bad air.
