DIR procedures forum?

Frank O · December 22nd, 2005, 04:34 AM

I was thinking of posting a general question on the DIR approach to bubble checks. It's not specifically DIR-F/recreationally oriented, nor is it tech per se ... nor does it fit exactly any of the other forums I see listed.

So, given that there is ample forum coverage here of DIR equipment, how about a "DIR procedures" forum? I.e. a place to talk not only about bubble checks but also S-drills, the finer points of clipping off gear, etc, etc -- all of the procedures generic to DIR diving in general. I don't really see these as fitting in any of the existing forums.

Frank - my initial reacion is that's not a bad idea - it gets round the point madfe yesterday by someone that there is not anywhere where changes to proceedure can be made available to everyone quickly and easily.

What does everyone else think?

I think it is a good idea.

I think a "DIR proceudures" forum is a great idea!!

To answer the bubble check question, I have found that the attention to detail varies considerably. On a wreck dive, we tend to stop at 6m on the way down, get neutral and bubble check each other one-by-one. It's much easier to see any leaks at 6m than in the darkness at 60m!

On a cave dive, bubble checks are done on the surface, this tends to involve a detailed look at the manifold area but often neglects a good look around the pressure gauge, stages, argon bottle etc.

It's much better to detect any problems at 6m or on the surface. At least you get a chance to fix them and then continue the dive.

I think it is a good idea as well. We could split it up into Overhead and Open Water? How about a review from a GUE Instructor just to make sure all the "i" and "t" are dotted and crossed?

OK - it's bugged me for a while that we have two tech forums.... so I propose that we lose the top one (I'll move all the threads) and make it a proceedures forum.

For those of you who check the forum using the "new posts" option none of this will affect you

Sounds like a really good idea to me

and an interesting comment on bubble checks while we are at it

We always do them on every dive, but recently a few cases have come up that re-inforce that you really need to pay proper attention to them

1) I had brand new Explorer 40 where the weld on the corrugated hose did not go all the way around. Gas would come out at a great rate, but *only* when I was in certain orientations under water. Had we just done a cursory check at the surface we might have missed it

2) both me & buddy have acquired multiple pinholes in pioneer singles wings (next time i will get the eclipse or similar) *but* unless you poke around with the wing a bit, and move the diver around, the leaks are almost impossible to detect.

When did you catch the leaks? What orientations were they exposed at? Could you have caught them on an S-drill?
