I have my open-water cerification too (PADI). Fairly new at it, though.
It's interesting, near the end of the video, they mention depths of over 200 feet? Indeed, as they said, that requires specialized training,
experience and equipment (I'm thinking NOX.... or maybe re-breathers).
In any case, it's puzzling --- the connection to the Maya... exactly
how they accessed those caves....certainly not by diving; they
didn't possess the technology, nor is it lkely to be humanly possible without assistance.
Someone mentioned, there must be above-ground entrances somewhere. Surely, after all these centuries, the opeings must be well-hidden, perhaps in
jungle growth (or maybe in Mayan ruins??). Further, the cave complex could not be intact, anymore...cave-ins and such.
Still, for archaeologists, a tremendous find.
