I have already asked this and I can ask again: how a 70 ft dive is different from a 50 ft dive, except for the numbers given in dive tables? In fact, the answer to this question is already given de facto by dive operators in resorts in Cozumel, Roatan, GC etc: they will take any diver with any kind of certification to 70-100 ft (and even deeper; we were freshly certified in a quarry, went to GC, and after maybe 4-6 shore dives at Turtle Farm took our 1st boat dive, straight down to 120 ft) group dives, because they know diving deeper than 60 ft does not require any special skills. However, none of them will rent you Nitrox if you are not Nitrox certified because they know that using Nitrox does require special skills.I reject this "if" statement. AOW is a perfectly valid course, if taught to standards by a decent instructor.
