IDS_Bill:When we analyzed it, it was 96%!!! Kinda drives home the point of analyzing your gasses!
What do you mean? Is this a point of discussion?!?
Any moron diving nitrox without first testing the O2 level by himself, should loose his certificate at once! (before loosing his life...)
I did the dives, but would have been bored to death had it not been on a nice Egyptian Reef.
Understanding the principles, doing the calculations AND being told to do the O2 tests should do the trick I think.
I feel that combining Nitrox with the OW-course is not an option. OW-students are usualy too much busy to just 'survive'. Give 'm some time to get used to diving...
