Last night I watched a program on OLN about cave diving in the Yuccatan. The program was about the cave systems explored by Mike Madden, Lara Popyack and a guy by the last name of Zinczenko.
Several oof the video clips from inside the cave showed a canister clipped off to the line that had been laid. Can someone tell me what those canisters would be and what they are for?
The show kind of made me want to do some cave diving--truly beautiful video.
