That really is Cold Bob3!!
My primary dive partner Ice dives. He, like me dives wet. The coldest water I can handle effectively is 48F (9C).
Next month we're going cave diving up in North Central Florida, "Cave Country." Some of the best dives are Diepolder III, and EN. The water is 70F to 71F (21C), much more comfortable than Ice!! I almost get hypothermic just thinking about it!!
