It is easy to state that you can develop a narcosis tolerance. That may be when all is well and all you have to do is maintain your buoyancy, frog kick and remember which way is out. What about when the sheet hits the fan? Your brain processing skills are already significantly reduced at those depths on air and sharing air, gas loss management, searching for lost or broken line in reduced viz or towing/being towed would send that developed tolerance right out of the cave.

It is similar to the person who says they can drive drunk because they have a developed tolerance. Meaning they can stay on the road and not run into the car in front of them. When those signal processing skills are needed they won't be there.

These are just my opinions.

I have had to bail out another diver below 200' on Air on more than one occasion.

Like I already said, I'm older and smarter now. I haven't used anything other than Nitrox or Trimix for ANY dive in several years.

Enough said about that.

It is amazing just how much stress and task loading can add to that equation. After doing a number of dives to 175 while spearfishing, with no problems, I found myself narced big time at 150 during a class. The more I tried to figure out what the instructor was signaling me about, the worse it got. I had some congestion that had caused me problems clearing that weekend which may have added to it as well. Bottom line is every dive is different.

Hey Knuckle Heads!!! ( I mean that in the most loving way)

Rennekar banks 21/30 (duh). A lot faster and easier than working up a mix. If you work it right, a backfill later with air will still get you some benefit from the remaining helium plus two dives for a little less $$$.

I thought that was the case I Pm'd Speloe that since they have it as a set price item at .25 per foot on the computer.

Thanks, Angie. I wasn't aware that Bill was pre-mixing 21/30.

DeWayne, my Air narcosis tolerance varied, depending on the visibility. I've been narked in murky water at less than 150', and I've been pretty clear-headed in clear water at more than 250'. Some days were better than others.

I remember making a wall dive in 1990 at Andros Island to 270' and getting narked, then doing another wall dive the next day to 281' and being clear-headed. Those days are gone forever for me.

Hahahahahahaha. Wow! I start feeling drunk at 90' (1 martini). By 100-110' I start losing short term memory. I 'don't remember nuthin' about depths sans helium greater than that. Then again, I'm a cheap drunk too - unfortunately NOT a cheap diver.

So you dive mix at Little River and Cow?

i was gonna say, i'm glad i can deal with some depth, i couldnt imagine paying for mix everytime i wanted to dive to 100ft.

A bit because not needing testosterone to make good decisions, my 'stones' are not proportional to size of my brain. I actually acknowledge that it is better to be a straight diver than to be afraid of ridicule. My buddies can count on me to have a clear mind and a 'stone cold' attitude when the feces hit the fan. I'd say that's worth the extra bucks. 8)
