| Re: CCR Trimix on an Air Dil Cert I added helium while on mod 1 certification because I nark badly and at 38m on air I can be too slow to fix problems succinctly. I did view sticking to the no-deco limit as staying within the intentions of the restriction.
I now have mod2 and, OK, I have put a hypoxic mix in it when I've been at 60m as I can see a DIL flush being a problem. I'd like to do mod3 some time but my seasickness problem means that I miss a percentage of dives on any trip so there are problems planning here. It's not that I want to go deep but I gather there are some good get-out-of-jail-free skills to learn. |
