I have tried to watch the video a couple of times. I can't seem to make myself watch all of it. The sound you hear is the regs. The tunnell is tall there and the diver isn't close enough to hit the ceiling. There was questions abut them pulling on the line, well that line is actually a thick cable anchored in the ground. Without some heavy bolt cutters it isn't gonna break. I have even used it as a method to conserve gas. Hetland the info you post about his supposed 232 minute dive is interesting. A dive to 140 ft there is only about an hour dive, maybe an hour and half if you play around some. Not enough to poke in at that depth to justify that kind of run time. I kinda think that dive log entry is highly padded or bogus. There is no gear, trim or techniques in this video that show anything but reckless diving. As it was pointed out by Cave Diver, conservation is any true cave divers number one concern.
Thanks for clarifying about the "guideline" really being a cable and not easily broken.
