Single tank, OW gear, at the beginning of the dive. We left the cave and entered the open sea to admire the reef.Presumably that was with single tank, open water gear. I don't think you and the trained cave divers on this thread (I'm one) are talking about the same thing at all. Cave diving involves traveling thousands of feet back in underwater river systems with absolute darkness and complex navigation to return to the exit, and is always done with specialized gear and extensive, cave specific training.
You might very well feel comfortable in the confines of where you were diving and there is a certain stability to cavern and cave zones. But what you're talking about is very different than actual cave diving as defined by the various cave training agencies.
