I haven't done that much diving in Florida, but each time I have been at Ginnie, it has flummoxed me as to why anyone uses that place for OW training. The river run itself is extremely shallow, so in order to get enough depth to do any "diving", the instructors seem to take the students down the vertical part of the Ear, and into the round basin of the Eye. Going into the cave from the Eye is clearly a major change, but to go from the chimney at the Ear into the cave is a very subtle change. I could see a student, having been there before and done the chimney, ending up in the cave almost inadvertently, and looking around and thinking, "Hey, this is COOL!"
I think there have to be better places to train OW students than Ginnie.
I totally agree! I did my rescue course at Gennie and Devils Den because the LDS grouped it with an open water class. There is a total lack of room for open water classes with all the other divers in the water. The allure I guess is 70 deg water in the middle of winter instead of the 50 degree water at Lake Rawlings. It was my one and only trip there.
