Hello,

OK i'll make the easy choice for you. Look at both sides of the issue(s) then make up your mind and go with that. Right wrong or indifferent. About the only words anyone could give is be as safe as you possibly can within reason.

OH and VTWarrenG, I find your horrible critic skills highly offensive, degrading and insulting. Seems to me you have some strange desire to start a topic and get everyone up in arms over it and then walk away. What a shame. You must feel proud.

Warren good description of yourself.
However I do not choose to be your babysitter

I believe the discussion will continue as long as we are breathing air at the surface. It is your choice to join in or not.

I do take offence of your judgmental opinion of me personally. I do find that when " a roomful of two year olds hopped up on Coca-Cola" run out of intelligent things to say they generally resort to name calling, actually maybe they would need to be at least six.

In the future warren any posting you see from me you can regard as directed at the rest of the people here and not directed at you..... You win... so take your ball and go home.

I for one find the balance of this discussion interesting. I am about half way through Lost Yoopers links and find a few good ones in there. Even if most of them do speak to both sides of the issue.

As far as the links I have read so far go they basically describe the description, signs, symptoms, and effect of Nitrogen Narcosis.
The one from Jacques Cousteau's book, The Silent World is the most interesting and probable most accurate description of being narked. It makes it that more interesting because of who wrote it, when they wrote it, and how indecent they were when they wrote it.

They all say you are narked at 2ata 33 ft.. Bad news for you END at a 100 people. Now you got to have an END at 30ft. or have you acclimated yourself to diving drunk

Another thing I am finding interesting. In order to strengthen my argument that deeper END are ok I have been running profiles and find that staying at 100 doesn't really lend itself to much more deco time. What’s 20 minutes when you've been there two hours already? As long as you can carry all that gas.

I personally try to keep my END at 130 but maybe a little shallower wouldn’t hurt

LY
ANDI's non helium based classes have a max of 165.. The web site hasn't been updated, there are a few other mistakes.. The 190 originally came about upon the insistence of one of the ITs and even then it required special permission from hq.. It hasn't been authorized in quite some time and has offifically been removed..
The extended range class doesn't extend depth it just introduces unlimited deco and unlimited gas switches...

This is a very good link.
Except that I don't think anybody's brought up decoing on air. now that is stupid.

Darn it, that's the second time in a week I've had to clean my screen...

Why don't you and blacknet just cut to the chase, talk external catheter sizes and get it over with.

In my case the higher o2 content on deep dives isn't an issue.. I dive a ccr so my po2 is whatever I set it for.. The draw back is at times I have an END that is deeper than Air, thats why I will not go beyond go beyond 200, when keeping the po2 reasonable say 1.3 I'm only at 18.4% so my n2 is 81.6, so my PN2 is around 5.8 if I allow of Po2 of 1.4, my o2 is 19.8% and my PN2 is around 5.6. 200 is my planned absolute max (for an excursion if something warrants it) but realistically I'm going to shoot for the shallowest point I can do the dive at. I have hit PN2s in the past considerably higher than this though I'll never do it again... air at 200 would be 1.5 po2 and pn2 is under 5.6... I know there are probably some rounding errors so don't get anal on me.. at this point it doesn't make much of a difference..
and believe me I have been trying various ways to get helium for my trip to truk..
one of the only possibilities I had was to buy a k cylinder in guam for over $400 (assuming they have one to sell at the time, then find someone who wants it or pay a disposal fee after its used) and pay $1.10 a cuft and buy 240 cuft of gas.. so far 664, plus shipping which they couldn't guarantee ... Then get kiss the captains ass to get the He on board.. All hope is still not lost, I'm working on trying to get a single 80 filled with 100% He, That will be more than enough gas for 10 days of diving..
and If it doesn't make it the loss isn't that big..

this one is very good and to the point on the whole subject of tech diving

Lost Yooper,

You truely amaze me.

Please inform us as to which thread you lied on. Either:

a) this thread

I should say that I, too, have done my share of deep air diving and never had a problem with narcosis -- nothing ever went wrong on those dives.

b) this one -> http://www.scubaboard.com/showthread.php?s=&threadid=5966&perpage=15&pagenumber=3

Personally, I consider sub DCS as being "bent". I was getting "bent" (very tired, sluggish, etc.) on every deeper dive I ever did on air and using a computer for deco.

Seems to me you have some double talk going on. Either you have had problems or you have not. It's like pregnancy, you are or your not. Care to clarify?

Ed,
In the first post LY is clearly stating that he never had a problem with narcosis.... but that is because nothing had gone wrong... if something had gone wrong then his diminished capacity to handle problems would have become apparent.

He was lucky.


In the second post Y is clearly stating that he had problems with subclinical DCS and he is attributing that to AIR and Deco Computer.

He was stupid.

To help you sort this out:

No problem with narcosis because he was lucky and didn't have a situation that needed thinking.

Had problem with Sub-DCS because he was stupid and used air and deco computer.

Uncle Pug,

Thanks for verifying my understanding that LY's two statements were perfectly clear and weren't in any way contradictory.

Though you made one small mistake. For the first statement you said that LY was lucky, the second stupid. I think for the first statement that he was both stupid AND lucky.

I know that’s how I refer to myself when discussing my deep air dives.
