OK, before everyone starts screaming "Don't do it!", please give me your thoughts on the comparison between the two. In other words, I am interested in whether you feel that the narcosis level is more severe on CCR vs. OC. Also, I am curious at what depth you personally feel that the narcosis level becomes too severe on CCR.

Just so we are all on the same page, let's pretend we are all diving in warm, clear, still water. Work load will be moderate.

Please no lectures on the disadvantages of diving deep on air. I think that everyone on this board is aware of any issues with deep air. I am just interested at what depth level it becomes unmanageable for you on CCR and how that compares to your OC experience.

Thanks in advance,
Randy

Hi.

I do not feel any difference, but I am concerned about the WOB on CC. If you get a CO2 build up, in my experience, the narcosis level quickly rises (and maybe to an unmanageable level!)

So as I see it, you can go equally deep, but CC may quickly bite you somewhere unpleasant

if you are in the extended range region or below.

Best regards
Morten
