Near-DIR diving: Are there DIR things you would probably never do?

[grazie42]

You have to start somewhere. (it is a drill after all)





So...if you know your right post is leaking, do you go for your isolator? (because thats how you did you drills)

You quoted me before I had time to moderate my own post but nvm...

To answer your question: If I knew that my right post was leaking and I had no other issues then I´d have the time to "stop, think, react" and I would close it first.

If the failiure was part of a cascade of failiures that left me "deep in the incident pit without a shovel" then I think (haven´t been there in diving) I´d go for the isolator because that is how I´ve trained and it would be "automatic", to not do it in the sequence I´ve practiced would require mental effort and thought...This is my experience from other analog pursuits...that is the "point" of drills after all, to ingrain responses so that they become automatic...

I recently had occasion to use a regular length hose to use while doing air-share drills...I still ducked my head to clear a non-existant hog-loop...And it took a whole bunch of repetitions before I stopped and every sucessful repetition required me to "force myself" not to duck. The moment I stopped thinking about it, I´d start ducking again...

My POV is that I train for what´s "right" in the worst case scenario and "suboptimal" in less-than-worst case scenario. I´m comfortable with the trade-offs that strategy results in and not comfortable with the trade-offs of the dir-strategy. It doesen´t bother me that others feel differently about it but it won´t change the way I do my drills...

Then, as far as muscle memory goes. Your drill and my drill is the same. There will always be a real life situation that can be different than the drill. So to talk about drills means nothing.

So, the real difference is why DIR goes for the right post as a last resort vs the isolator is the meat of the matter. (which is what you stated below)

Otherwise I think I´d go for the isolator because I know it would save the gas I need to complete the dive on my own BG and free mental resources to handle all the other issues that I may be going thru. To me this is part of planning and training for "worst case" and as doing it any other way would only save gas that I don´t need, I only see increased risk for little added utility.

I think this discussion has been had repeatedly in this and other forums but I think I´ve clarified my POV now...at least I hope so...

The difference is really on how you play the odds. There is no right or wrong answer, but there can be a DIR answer and a non-DIR answer. We both understand that they are not the same thing. Right?

Going to the Isolator first absolutely guarantees that you will save 1/2 of your gas.

The reason DIR goes for the right post as a last resort is that it is almost always the culprit. And if by chance I was totally wrong, my buddy should have gas for me.

So, if I was a solo type diver (or semi-solo). I would go to the isolator first too.

I´ve re-written my post again...I´m afraid....maybe it´s more clear now JeffG...sorry

I agree with your basic premise though...It´s how you view the odds and the consequences of different outcomes...There is a right and wrong, for the individual, but that is obviously not a "dir-answer" and while I respect that, it won´t change my mind...

EDIT: Since I am planning for multiple failiures...and team failiure is one such POSSIBLE failure (even for a dir-team)...I wouldn´t practice something that leaves me without the gas I need...

I also realize this violates the "number of sucessive failiures to plan for" but as it´s "free" I´d rather do it, than not...I don´t think I have a lesser expectation of team-cohesion than most dir-divers but separation is an integral part of all cave-training (even gue- cave training I believe) so it seems not even they see it as an unreasonable failiure...

DIR: Just a bunch of frog-kicking automatons.

and there is nothing wrong with that. Most times there are more than one way to skin a cat.

Even one that´s holding an ak47 with autofire?

Those kinds can never be skinned. Too mean.

The threads in the DIR forum are so full of trolls that the mods keep moving them to other forums. In fact, this thread was one of them.

Actually, mods generally do not move threads from the DIR forum if in fact they belong there. Even when those threads are rendered hopelessly convoluted by SB participants who either do not understand or who refuse to abide by directions to only respond with DIR answers.

We only move threads from the DIR forum that had no business being there in the first place.

Why aren't mods keeping posts from getting hopelessly convoluted?

Or just angle the compass so the lubber line points ahead even when your arm isn't orthogonal to your body. Seriously, I know a lot of us are reading our compass with our can light in the left hand and NAILING our navigation. Maybe you just need to practice?

What, I need to practice navigating without being able read my compass? Seriously, seeing in the dark is not a skill you can work on.
