My first cavern dive was with a VERY experienced cave cartographer (Yucatan Cenotes, https://www.filoariannadive.com/alex.html ). Cavern is where technically "you can see the light", but if you turn a corner and can't see the surface then it converts into "cave" diving.

For the rank amateur that I was, being able to turn around, orient myself and see a sliver of light ~100ft behind me... yeah, "technically a cavern dive".

I tried to do a "buddy check" w/ him before beginning the dive and he almost pushed me away... the stories of him diving with side-by-side tanks, then pushing each of them through a gap in front of him, one by one, and then wriggling his body through. :insert-shocked-emoji:

Always remember: "Are you a diver, or a dummy?" ...what would a DIVER do? [don't panic, fall back to your training] Good to have that sense of self an security in lots of cases!
