Diving air to 60m

[Wingy]

Of course Hypercapnia is not normal....!! Does not mean it is not a condition that doesn't affect OC divers who've been put (in my case) into a very sudden stressful situation requiring a very heavy physical workload when a SHTF situation arose. No I didn't see a doctor, I recognised it for what it was and thanks to having a few good mentors remembered my training and dealt with it.

If a diver is getting Hypercapnia for no obvious reason then see a doctor. If you have one chance to fix a fk up and it means you get one helluva headache then do that. I can't see anyone wanting to experience Hypercapnia for the fun of it.

The increase in WOB at 60 meters is hardly noticeable and a load of hype

You cant be serious

While narcosis might be subjective TO SOME EXTENT, gas density IS NOT.

I can only excuse your responses to scientific facts by hoping that you are writing them at 60m... on air

Hypercapnia, a favorite buzz word among divers and a non issue on open circuit, not only did I work hard on air but used crow bars, water lances, cutting gear. lifting bags and laid explosives without suffering as much as a minor headache. Anyone with any symptoms of carbon dioxide toxicity using open circuit diving gear needs to consult a professional it is not normal.

I watched a guy black out in 240' of water on air while he was exerting himself like crazy.

To move the discussion on, should it have been 18/35 or 18/45 in the single 12?

18/45 for sure

I don’t doubt you for 1 minuet but that can happen if you drive yourself past your limits in any sport. I’ve seen people collapse while running and rowing. Obviously you don’t drive yourself to the limit while diving.

Anyone have this book and would like to sell it? It sounds like a great read. I know it's on kindle, but not really my kind of format. Thanks.

Think I found it in Australia in new condition. Fingers crossed!

Now that someone has gone to the trouble of moving all this stuff I’m going to make my position clear. The notion that you are more safer at 60 meters on a rebreather or trimix than you are on air is a myth. It’s not about the method it’s about the person using it.

You better tell that to GUE, IANTD, TDI, CMAS and a bunch of other agencies who apparently have bought into that myth, then.

Or are you just trolling?

Put forward your argument that I’m safer on a rebreather or trimix than I am on air and stop telling me what other people do.

Ok, got it. It's option #2, I understand that now.
