What would you do about the young thing that got her 100 dives for instructor by doing 20 20 minute dives per weekend over 4 weekends in 22 feet of water off the dock? What would you do about the quarry divers who haven't gotten their gear salty yet, yet have hundreds of dives? I'm not arguing with you, nor do I necessarily think that quarry divers are bad divers, but there is wayyyy more to it than a minimum number of dives. The young thing was, by the way, "doing" her instructor. What they were doing, I don't know, but since she certified before me, she got the opportunity to staff the final NPS mission to Bikini Atoll for Department of Energy. She was not an NPS employee, but we Department of Energy types were allowed to staff and support the mission if we were DM certified. Since I wasn't able to provide the extra-curricular activities she was for the instructor, I wasn't picked to go. I finished my 60 dives the old fashioned way, by diving.
The point is, you can find good instructors and you can find instructors who just want your money. The training agencies don't really care, they get your money either way.
