Some very valid points but it does not change the fact that while the safety info is exactly correct there are still boats leaving to dive the Blue Hole every week...
I'd suggest to you that the manner in which a dive is conducted by the boat operator (however "safe") cannot account for how a diver will be affected by narcosis. There is not one "expert witness" that in court will side with the operator in case of an accident. Deep diving over 130' requires further training and experience without exception.
If you drive on the wrong side of the road on your way home this evening and are finally stopped in your driveway, I hardly think that a statement to the police that "no one was hurt" will be held to be a reasonable one. Breaking the rules and getting away with it doesn't mean it's morally right or even a smart thing to do from a business perspective.
All it will take is one death and the dive operator and the attending DMs will be eaten alive. I wonder if the DMs doing this dive daily realize that their liability insurance isn't worth anything in the event of an accident. Why? Because it's unsafe practice!
