DIR: God's gift to diving or Hell spawn?

[Boogie711]

A) Pipedope, I don't have any rights to ask anybody anything. I was simply, humbly, asking. However,

B) GJ62 and I have actually been known to agree on things. Unlike a few members of this board, I have a few little smidgens of respect tucked away in the cold dark recesses of my hardened heart for him. And on this "you don't need to buy Halcyon" point, I'll back him up on that.

Pipedope, that's nearly a marriage proposal from Boogie - I'll take what I can get...

DIR is the mis-application of cave diving protocols to non-cave diving.

The term DIR was stolen from early cave diving, which formerly meant "two of everything."

You mean he was so hung up on it that he wouldn't take in a bunny dive in paradise?

Yes, unfortuntly. And the topic is why people get turned off by the subject, not whether DIR is good or bad.

He made a really poor spokesperson, turned me off (and many i worked with). They way he talked, and represented what DIR was, did not impress. Fact several people got this impression.

enough to differentiate between the message from the messenger.

I wish that I believe that. It seems to me to be more like, that presentation makes the argument. this is the premiss of advertising, fashion, car styling, cosmetics, and may other endevors.

In any case, that said, several (4 or 5) engineers at a well known eneineering firm did not seperate the message from the messanger and thought that DIR was a fools game, because a fool was touting it, and there was no one else to defend it.

LOL just when you go to hit "report a bad post"... someone does it for you.

 

[pipedope]

With passion and commitment, but NOT with personal insult.

Thank you for keeping the focus on the discussion at hand.

But you gave this in an earlier example of the things GUE did come up with. Jeesh!

You misunderstand. They did not come up with the concept of having enough gas to get you and a buddy back. That concept goes back to the days when Seck Exley began analyzing cave accidents and wrote a book called "Basic Cave Divingand a Blueprint for Survival". They began to use the rule of thirds fo gas management.

GUE modified it to be more appropriate for OW diving. The idea is to still have enough gas for two people to end the dive on but in OW the rule of thirds is sometimes overly conservative. They call the gas needed for ascent (for two people) rock bottom. Everything else is usable gas. If you must get back to the entry point you turn at 1/3 used max which is the rule of thirds from cave diving. If you would like to get back to the entry point but it isn't critical you can use half the usable gas. If you can surface anyplace you can use all of the usable gas but you still have enough reserve for two divers to ascend on.

Do you understand GUE's contribution? They didn't develop the concept but rather the application/clearification/simplification. ok?

Not really. The DIR which is applied at the DIRF level doesn't have a thing to do with cave diving. It's just diving with a mostly hogarthian configuration, solid basic skills, good buddy diving habits and good dive planning methods. Simple.

In fact, most of what's taught in a DIRF is skills that divers should be learning in OW like hovering, trim, finning technique, how to plan a simple OW dive and how to keep an eye on a buddy. The class is really just meant to get your basic skills to the point to where you're teachable.

Read the standards for the class. It reads like an OW class with the addition of deploying an SMB/lift bag. They just try to get you to do it well as apposed to just giving it all lip service.

The term DIR was stolen from early cave diving, which formerly meant "two of everything."

I've read almost every cave diving text there is back to the very first. I have never seen the term DIR in any of them other than the GUE cave text which is a "recent" book realtive to cave diving.

I've been told by several people who should knw that the term was first used in a NAUI text though I haven't seen that text. Somewhere along the line members of the WKPP started using the term.
