Come now kids....lets all act like adults assuming you are over 18!! :shakehead:

It does appear as though the 'Non DIR' divers are taking a lead in this very non scientific SB poll. ;)
 
You have touched precisely upon one of the many major flaws of GUE-DIR: the lobotomic application of "standardized" procedures without the allowance for individual applications of judgment, thought, and freedom by any of the herd of sheep. The top leadership of GUE-DIR may be allowed to do the thinking for them and promulgate newfangled "standardized" protocols, but the sheep must follow obediently, even when it leads them to the chamber.

What makes you think we don't make allowances? Do you simply follow the deco schedule that V-planner spits out for you? Or do you give some thought to the circumstances of the dive that V-planner simply can't account for ... such as water temperature, current conditions, and how you're feeling on a given day ... and adjust the schedule based on your understanding of what will make you feel better at the end of the day? Applying ratio deco isn't any different, ya know ... you just do it within the tenets of rules that make it simpler to follow if the condition of the dive requires you to make that decision during the dive ... when you don't have access to your laptop and dive program.

I really have no idea what the top leadership of GUE-DIR think ... I don't interact with them.

I read this and reflect upon my Rec Triox class, and there is such an enormous disconnect between the belief and the reality that I can only shake my head. NOTHING I've learned from GUE has been written in stone, except the basic equipment configuration. With regards to deco, for example, we were told about Buhlmann-type programs, about ratio deco, about deep stops, about the oxygen window . . . And then we were shown how GUE's approach incorporates portions of each of these to create a useful deco strategy. We were also told about factors that should be weighed in deciding how to create a schedule (like cold and current) and also advised that very experienced deco divers learn over time how to tweak a schedule to best fit their own physiology. No sheep, no shepherds. Thinking divers.

Heh, heh.

Go into Extreme Exposure sometime and buy a mask (or something), and watch the sub-species interact... tell the guy behind the counter that you know AG... show them your NAUI Instructor and Trimix cards when you rent a couple of tanks... try not to puke when you leave.

If the best you could do before was to tell me that your deco on the fly simply equals the equivalent of +2 on V-Planner, then it seems self apparent to me that your deco on the fly is too aggressive for all divers.

If now you are adding to your story and saying "Oh yah, we can make it more conservative if we want," then that is inconsistent with your first story.

Even so, either way, I think you should trash deco on the fly completely, and stick with computer programs that generate profiles planned in advance. Not that it truly concerns me, however. In fact, it would be better if you simply keep doing what you are doing. It gives the local chambers more practice, that way. They need practice. They are not getting much practice from anybody else.
 
Indeed, even as I have listed its strengths, supra, juxtaposed beside its self-evident weaknesses.:D

BFD. Until you can show WHY and HOW they are weaknesses, then they are just more BS strewn about this board that are useless to everyone.

:shakehead:
 
Yep another vote for 'no deco on the fly'....better ways to to plan staged deco dives....course this is just my thinking....I know a few divers do it another method and live to tell. Heck fire I use GUE's Deco Planner and customize as I feel appropriate in my planning. :)

I guess I am just getting old, and these newfangled terms are escaping me. When I learned this it was called either hypoxic trimix (%O2 < 21% + HE), or normoxic trimix (%O2 > 20% + HE), or nitrox (%O2 > 21% without HE), or air (21%O2, 78%N2, 1% other), or 100% O2.

What is Rec Triox? Forgive me.

As long as you are diving NDL with GUE-DIR you should be ok since they have excellent NDL protocols.

It is their deco on the fly that is questionable, if not hazardous. Once you get to that point in the program, it is time to re-evaluate for yourself. As I am sure you will see.

You remind me of the guy on shore leave at Subic Bay who would not bring condoms with him because no one could "prove" to him they were a good idea. He had to find out for himself. It was a really big needle too, so in the end (no pun intended) he finally got the point (no pun intended).
