Ive been there, and it is a blast. Comment from the tour guide to the newly wedded couple before the trip was to the bride "do you have insurance?"
Also he mentioned that they use plastic cages , so as not to hurt the endangered species of shark, Lol this was a joke of course.
I looked at the welds on the cages that we climbed in, Made of Rebars and not very strong. All added to the experience, glad you enjoyed!!
Ah brilliant! Our guy was telling us that they use the birds to find out where the sharks are. They were throwing pieces of bread into the water and if the birds took the bread, we moved on to another spot. When the birds refused to take the bread from the surface, thats when they put the cage down. Pretty clever :-)
