Popeye once bubbled...
I spend a lotta time in quarries. I'm with you all the way. Gilboa wasn't bad when I was there (Sat), but it was in the Spring. I think relating to the owners is a good idea, but a first dive is always gonna be a first dive. The local quarries (Nashville Knoxville Huntsville) are all the same way.
This is my point exectly and is the first thing that MUST change. Everyone believes it but it isn't true. If a student can't yet stay off the bottom they are not ready for open water. The sad part is many of these divers never learn to stay off the bottom. My own OW student complain about the mess they see divers make as they hover and watch them wallow in the bottom.
Reference the Jan/Feb issue of "sport Diver"magazine page 44. There is a two page picture of a blatant standars violation. All these student have dangling alternates and gauges and are being taken into the water by an instructor that I believe is incompetant to the point of being dangerous. There is no excuse for it. If these idiots can't afford the stuff to secure this equipment I'll sent them some bungie , snorkel keepers, tubing or whatever for free.
BTW, I didn't mean to say that accidents (no matter when they happen were the fault of bad training I said they were due to poor skills which certainly indicates poor training.
