An age-old question: ways to 60m.

And narc is a bit nice one you learn your style and ease into it (again I've never stated i don't get narc'd but that I'm not heavily affected by it).

For other readers coming here to learn:

Narcosis is not a “style” to be adopted by a diver. It’s a physiological symptom resulting from increased absorption of nitrogen from breathing compressed gas at depth. Choosing air to get a euphoric effect is a choice but not a prudent one.

Nitrogen Narcosis: What Divers Need To Know

What is nitrogen narcosis? What does it feel like? How long does nitrogen narcosis last and what is the treatment? Your questions answered.

You all get so bent out of shape when people do things under less than ideal (subjective) conditions.

No. We get all bent out of shape when people advocate for others to do stupid shift. Like deep air.

You can do whatever fills your boots. I really don't give a f. It's when someone asks the best way to go deeper and the joe boys say that deep air is an option that I get concerned.

It is an option, one that you don't partake in. Berating those that do shows true colors. Deep air is an option and the risks can be mitigated over time. Train as you would otherwise and know the constraints of the gas.

This is an illusion or just a lie. Gas density doesn't change through make-believe.

You really are a choice piece of work. It is not an option. Deep air is stupid. I did it. I realized it was stupid. So I stopped. Now I have little patience for those that preach to others that it is an option and I will, with extreme prejudice, pound down you and who ever else shows up saying that deep air is an option.

I only did one deep dive on air to 55 meters/180 feet on the Warren wreck (overshot it). I was diving with two other guys. One guy was so narced (and denied it afterwards) that he couldn't signal back "okay". His head followed my light on the bottom like a cat following a laser pointer circling on the wall.

I realized that if anything happened, we were incapable of dealing with it. Narcosis is a neurological syndrome in which no amount of diving/training will alleviate. I was trying to move so very slowly and deliberately to minimize my exertion as I understood that any increase in respiration would be problematic.

I tried to thumb the dive as my buddy was completely unresponsive to a simple okay signal. The other guy waved it off as he was determined to see the Warren wreck. Needless to say, I never went on another dive with those guys. We were extremely fortunate that we had no equipment issues. I am quite certain that if we had a LP hose burst (or burst disk failure), one or two of us would have drowned.

It appears that the only teacher here is going to be Darwin and there's nothing we can do about it.

someone who has done the training, has read the books, but hasn't given up the $$

I have total admiration for you and your honesty dude despite the bombardment from those with different ideas
I was wondering, if there was anyone left in USA that could think and do without having to ask others permission

OP already stated he does not feel good with doing deep dive to 50m on air so wants an alternative.
Enough wiith the bickering already. OP has been given options for different agencies that teach Trimix to 60m.

Some people recommend divers use Trimix and not Nitrox for dives deeper than 30m. That's fine

But I would rather do Nitrox to 30m, air for 35m - 45m. Yes I know Nitrox 32% MOD is 34m but I tend to cap it at 30m.. Just to be on the conservative side. If I want to do 35m - 40m I might do nitrox of 27% at PPOE 1.4 I don't use 1.6 which would allow deeper MOD.

I will dive 21% to 45m and do deco on air when no other gas is available. BSAC training I did before nitrox or helium was use for non commercial diving.

All diving has risks. We have just seen news of a very capable diver drown at 2m depth in Malta on a twinset as his gas was not turned on. That's a pretty basic pre dive check but hey, people make mistakes. A good friend of mine was at the site scouting location for social media at the time. He just moved to Malta and wants me to come visit and go diving there with him.

So yes for those who want to dive air to 50m - 60m which many agencies have taught, that is their right.
if you disagree with them doing that then that's fiine. They aren't asking you to dive with them.

@iho may have stopped posting and is considering options for deep diving to 60m.

My twinsets give me hours of time and I generally do deco on back gas unless I'm starting to get cold. Then I pull my 50% reg and breath down the 40 to clear a bit faster.

For other readers coming here to learn:

This is more evidence of a clear lack of training. @Boarderguy is basing his gas switch on whether he’s getting cold or not. This indicates the lack of a clearly defined objective that validates the decompression obligation, one that seems to have been generated in a casual way, and also indicates a lack of thermal planning for the known or expected exposure.

A properly trained technical diver defines an objective, develops a focused gas plan for the profile, tracks his decompression obligation, switches to the better gas at the earliest opportunity and plans for thermal needs during the working part and the resting part of the dive.

@Boarderguy You’ve chosen clown shoes and underwear as your costume for this show, not me.

Berating those that do shows true colors.

This thread has become about you and your desperate obstinacy. Two things that are clear to me are that none of us can coach or advise you to graduate from your hillbilly tendencies and you have no credibility in the Technical Forum.

The power to be better is in your hands.

So a diver who gets cold decided to end a dive early and do a deco obligation earlier than planned and that is an issue? I have a dive buddy and he has called dives because he got too cold in his 5mm in 22c water. I was cold but I was wearing T shirt and shorts. I did the second dive after the surface interval but my dive buddy I advised him not to dive as he was still suffering from being cold. He skipped the second dive.

Ending a dive earlier than planned because one is too cold sounds like a good idea to me.
