NITROX for any and all dives?

[MXGratefulDiver]

Well... actually... There is an agency called Global Underwater Explorers (GUE) which does this very thing. They advocate helium for any dive deeper than 100 feet. Well within recreational depths.

... they also provide the additional training and experience I was referring to. And although I disagree with their premise, they do provide their students with the requisite skills to pull it off.

Compare that to the IANTD Recreational trimix class I took in 2007 ... the instructor allowed his students to perform skills while kneeling ... in a trimix class ... let that sink in for a moment. If you don't have the buoyancy control skills needed to hold a stop mid-water while mildly task-loaded, you have no business breathing helium underwater ...

I was not aware that there was an IANTD Recreational trimix class--if it involves decompression stops, how is it recreational?

BTW, a recent study showed no real difference between helium and nitrogen in required decompression.

That's why there's gotta be multiple trials, over time the tank chosen for the first dive would approach 50/50 Air vs Nitrox. Just like flipping a coin. You do it 100 times you're going to get heads about half the time.

Explain to me why I have to cut all my dives short so that this question can be addressed. You paying for my diving?

Sure I'll pay for your diving. If your test results show that you do in fact feel better after diving the tanks that are subsequently found to contain Nitrox. If they do not, then you pay me whatever it cost you for those dives.

I'm in favor of those who feel there is no benefit not using nitrox. Those of us who prefer not to dive to the limits can continue using nitrox. Eventually data will show whether Wookie was right or not. As to feeling better, I've heard people with the bends don't feel that good.

I am in a situation where the cost is not really relevant. I have a bunch of family commitments. I could easily pay for more diving then I get done if I could find the time The most valuable part of the process is the time under water. I do good, given blowouts, to get in 5-8 days of NC coastal diving a year. I dive HP100s and find myself often riding NDL with 32%. I would not want to give up any of my precious bottom time even if you were paying for the whole dive trip. But thanks for the offer.

I will add that you need to factor in water conditions. If it was a rough ride in and out I will be more fatigued indpendent of what I breath

 

[dmaziuk]

... helium will bend you MUCH quicker than nitrogen will ...

I thought we now believe there's about as much scientific reason for that, as there's for being less fatigued and having wet mouth after a EAN dive. Has that been re-de-bunked while I was not looking, or am I mis-remembering?

Scoot over @Steve_C ...Great, I'll take those terms. Though if you're paying, I'm probably going to feel better whether it's air or nitrox... Are you buying the post dive margs as well? Just wonderin'...

Apparently there is.

Recreational Trimix Diver although from teh guide it does not mention anything about decompression.

However

Advanced Recreational Trimix Diver Has a depth limit of 48msw and max deco of upto 15mins. (Although this course is in their tech Lite section)

Not every agency has the same delineation of NDL dives being Rec and Deco dives being Tech as PADI do it seems
