I take it you meant to say: Mexico guided CAVERN dives where the guide takes the OW customers into the no light zone..Originally Posted by Kelly Jessop
can not see anything dangerous in guides taking trained cave divers into the no light zone?
Would that also include Blue Grotto (beyond Peace Rock)? That was one of the first "deep dives" I did after my OW cert. It was done both for my AOW and also for my basic Nitrox cert. To me, it was a "cave dive" disguised as a deep dive. This was, of course, before they opened up that new "real cave dive" section.
What, IYHO, are some of the main things that might be missed in those systems due to that "complacency" or "repetition?" I can think of a few...
1) Not paying attention to changes in current/flow and thus, adjusting the gas plan (i.e. greater conservatism than 3rds)...
2) Not paying attention to the lines and making note of any lines either "in" or "close to being in" disrepair (i.e. loose lines, etc.)...
3) Viz changes and/or silt outs (from a recent diver)...
That, and making visual jumps, in spite of the fact you know it isn't recommended. I hear things like"This is Ginnie, it is safe here" all the time, but there have also been fatalities due to unexpected siltouts, or buddy separation.

I enjoyed watching this documentary...
We could back to the DV3X days, there were quite a few Hindenbergs. You always wondered when you got on the trigger if you would have a 4th of July display

That was a Salvo Mojo in the now remodeled "Andrew Ainslie" suite.

In France you have the 'Bial' cave. The entrance is mostly no mount. A couple of times a year people need to dig the entrance out. After the first 7-10m the cave widens and is beautifull. Sadly the first sump is short (80m), but to go the second sump is not that difficult. Most divers never do this cave because of the entrance. The gravel will make it zero viz too. This cave is on my personal list of 'dangerous'. I like it, I dive it, but sometimes I think when I am in the entrance why am I doing this? After the entrance I like it again.
But yesterday, I read that the exit from Catfish to Manatee is now almost blocked so become really dangerous.
Cavediving at all is for outsiders listed as dangerous and diving, even open water diving too. Horseriding is dangerous, skiing is dangerous, driving a car is dangerous. Even staying in bed can be dangerous. My nondiving collegues don't understand that I like cavediving.
Funny that the video was not the Devil's System. It was actually Devils Den in Williston. FAKE NEWS
