Bobb,
The basics of this issue ARE suposed to tought in o/w course. I'll give you a schem of things, anyone else may add to it or reffer to it ofcourse.
Deapth
meters
0 -Surface.
6 -No decompression depth (to shalow to develop DCS).
18 -Beginning of Narcosis, unfelt by most people.
30 -Narcosis get's up another stage,functionality is reduced.
42 -Every one is narked here, rec. dive limit.
55 -Nark is STRONG, I had halucinations.
70 -Risk of O2 tox.
Deep diving:
It is highly none-recomended for none very experienced divers to go beyond 30 meters. Narcosis get's strong, and inflicts there everyone. Beyond 42 meters the risk of narcosis is VERY big.
About no deco times:
If I remeber correctly, there are no deco time up to 70 meters. It stays 5 minuets, but only getting there will take a few minuets.

Dear Bobb:
What happens when you go beyond the deco limits? Well, this is what the early compressed air workers found about 150 years ago. This was before decompression procedures were really developed and there were many on-the-job mishaps.
These early caisson workers started to encounter problems with pain in their joints and some of them even died. Yes, actually, dying was a real problem with the early construction workers on the Mississippi River Bridge at St Louis and the Brooklyn Bridge in New York. It still can occur!
Decompression is something that needs to be treated with respect. :nono:

I understand your wanting to hit 100'. My first year diving the deepest I got was 90' because that was the bottom of the lake. When I did get to 100', I didn't get ecstatic. It was more of a little "Cool" shrug. It was important to me, though. Then again, as a teenager, I HAD to peg the speedometer too! I can't remember the last time I drove faster than 85 mph. It's just one of them thar things - you can't explain it rationally.
To answer your actual question, 1-130' is supposedly safe for any AOW certified diver. Depths of 130.1' and beyond are mystical and reserved for the annointed few - so don't ask.

Being trained in the Navy in 73, one correction, max no deco (USN) is 190ft/60m, but as all have stated, there's plenty to see and do above 130 (and a lot longer to do it)
And as all have stressed, education and training is vital to safe diving, at any depth.
Being calm and cool is easy as long as nothing has gone wrong, learn and practice for any and all situations, you might save your buddies and/or your own life.

I'll echo my Texan friends here and say that there is more to see and do in the shallower areas. Plus it's safer and your air lasts a whole lot longer when you motor around at 60 feet or shallower.
Like Texass, I get a bit of a (cheep) thrill by discovering whats at the deep bottom of the local lakes. Usually very little and it's much darker and colder than above 60 feet.
Sorta by definition, recreational diving is supposed to be no-deco diving. So I encourage you to stay within the no deco limits proscribed by the tables and the computer.
Your question seems to be one of how do you handle things when you do bust the no deco limits. This is where a good diving computer will help you. If you do bust the no-deco time limit, most dive computers will assist you in getting back within the NDL (by moving to a shallower depth).
And take your time between training cources and pushing yourself to the next level of diving. There is plenty to do and see at your current level. And those advanced items will still be there next season. Ensure that you got your current level of training and skills down cold before you move on. And don't be afraid of seeking help from an instructor as you need it. (you wouldn't beleive how much free instruction I get when I start off a conversation with, "Here's a beer, and I've been meaning to ask you about......")
