NonAccident Analysis

William Trubridge does 280' no fins freedives, he's totally within his comfort level on that dive to 180....probably a higher danger for his diving safety divers than himself.

Skip, what are you driving at? "... the mistake of carrying one spool." I don't carry ANY spools. I prefer reels. And what's wrong with carrying just one if you dive plan is no jumps or gaps? My training said, "Number of reels carried equals number of reels you'll need plus one." Staying on the mainline, I carry one reel. (This does not include the primary reel, which is not "carried.")

I think two makes more sense and gives you more options even on the main line.

For example, you are on the mainline, and find a broken/missing section that requires a spliced section of line. If you only have one spool (or reel) your options are to 1) leave it unrepaired - a potential risk if anyone is in the cave ahead of you - or 2) use line off your safety spool (or reel) to make the repair, creating a risk with a shorter than normal safety line.

Carrying an extra spool is no big deal and I can't come up with a good reason not to always have at least two on a dive.

How about being lost off the line in zero vis. A high stress situation in which it is entirely possible to fumble/drop/foul a spool/reel while attempting to initiate a lost line procedure. Now you have to spend time groping for the lost spool/reel, if you can even locate it, or attempt to unfoul it. I have seen students do this numerous times during drills. It is much quicker to just deploy another safety. I teach to always carry two extras.

Of course you could argue for three or four or twenty, lol, but two seems to be the best solution.

YMMV

If I carry spools I always carry two because one invariably comes unclipped and I find it on the exit. I only carry one reel 'cause that never self-detaches.

How about this? theses guys go on a 300-400 meter penetration and swim right by the warning signs we put in place totally ignoring them.

Well, Phillip, "comments" for this video has been disabled, so they probably already know what we would write.

I just noticed that, the dive shop that took them on this "tour" was Scuba Fun in Bayahibe
