Really....There's plenty of single tank Intro. to Cave divers out there. Why wouldn't they be allowed in a cave as long as they dive within the limits of their certification/experience??
There might be plenty of them out there, but realistically, there's not many diving in the common FL caves. I've been cave diving about three years now, averaging about one trip every couple weeks, and I don't think I've ever seen one yet.
In my opinion, it's another one of those ideas that sounds great in theory, but doesn't work in the long run, kind of like the people who get into BPW's and figure they can get one wing that works for both singles and doubles. That's why you see people selling their Y & H valves on a regular basis. They realize that if you are going to cave dive, you need two tanks.
