I have taken fairly new divers to the Blue Hole - but only if they are certified and have done at least one day of diving the reef here with me. Then I insist that my experienced dive buddy and I stay right with them. We explain narcosis because they will most likely experience it.
Even with all these cautions we almost lost one gal. She broke away from us so quickly and dove straight down. Her husband went after her and got her just before she reached 200 feet. Back on the boat when quizzed she said she just wanted to go down and see the pretty sharks. Of course, once back on board she realized how dumb that was.
One thing I tell everyone - "I won't die for you." You want to do something stupid and die or get the bends you can do it by yourself.
I can't believe that a dive master would consider doing the hole without a computer. The deco and safety stops are so important.
I still do the Blue Hole occasionally even though I now find it rather boring - The next two dives are what makes the trip worth while. Even better is going out to Long Caye for a few nights. This way we dive Turneff on our way out and way back, are at the hole first thing in the morning before the day boats get there and get to do some of the other really great sites along the west wall of Long Caye.
The east shore in the cove by the dock is where the spotted eagle rays sleep.
