I realize this is quoting an old post, but think it bears mentioning. There is a third option. Rather than swim along side the rocks or try to chase the group through a maze of turns, you could go above the rocks and likely either see them from or their bubbles from the higher vantage point...

I've always found storing them in my brain to be fairly convenient.

Child's play

The GUE swim requirements aren't particularly herculean. The pace of the rec requirement is 1.2 kph / .73 mph. I believe it's meant to be attainable to people who don't swim regularly as a form of exercise. In 14 minutes, it's 275m for rec classes, 375m for level 1 tech/cave, 450m for level 2...

That regimen maybe. I just swim through (generally all freestyle), though. If I'm in the water by 12, I can do 1800y, take a quick shower, stop somewhere on the way to pick up lunch (calling ahead as soon as I get out of the pool) and be back right around 1. It is more than an hour with the...

Where do you swim? You still at NG Redondo? I'm in the R9 building. I swim at the pool by hawthorne highscool at lunch time (lap swim opens at noon). Want to join sometime? It's about time we actually meet.

I swim 3-4 times a week, generally a mile each time, sometimes more or less depending on how much time I have. That and weight training.

Like the myriad of complaints about "DIR", I think people assign too much value to what dive classes or philosophies are called.

And, I believe that most agencies have text akin to "or equivalent" in their requirements, for which experience often counts. I have at least two certs which directly require "advanced open water or equivalent," and both instructors accepted experience in lieu of that cert (which I do not hold).

Just to be clear I wasn't arguing your point; I think it has a lot of validity. Just wanted to say that the boat and the diver both being there isn't enough ;) We finished the deco. With O2 it was only circa 15 minutes. We didn't have the upline though and surfaced much further from the boat...

In my scenario (which is posted a couple places), I simultaneously lost the upline, my light (primary died because the connector detached from the battery; dropped a backup) and my dive team while diving with an obligation at night in poor viz (roughly a foot where we were decoing) with heavy...

That may have been an impetus to split what was once a 5 day class into two 3 day classes (without an additional charge): get the blind stuff out of the way before going into an overhead. It also facilitates teaching the commonalities between Cave and Wreck at the 'Protocols' level and leaving...

I'll add my 2 cents. At least in my experience, the mechanical skills such as using a reel were the least of the course. Fundamentally, Sheck Exley's rules for survival + 1 are taught, as are protocol for blind communication on a line, lost buddy, lost line, etc. But once you hit the water, it...

I imagine every situation is different. I've only felt anything approaching panic while diving once, and I don't know if that experience would in any way play into another.

Fortunately not any more. But I am lucid enough that I'd take a free trip to the red sea in exchange for a questionable open water class. After all, I'm a certified diver ;)

ZING! And, no. I've been busy with this little guy

Dumbest thing I've ever read. :P

It's explained in this old thread: http://www.scubaboard.com/forums/basic-scuba-discussions/164988-pressure-depth-cave.html

I use my suit for comfort. My wing is for buoyancy.

I was just going by a quick web search. YMMV
