Thanks

Never !

Start with heliox 6/94 and finish with it

PpO2 varies not the dil, are we on CCR Yes or No

Just go to O2 at -12 or -6 on OC depending of the cave config

Aldo can you had a line in your pool options, as:

"Never"

Ciao

Hi Jerome
it had to be anytime, but I have been wrong.
How do I do to correct?
I have tried but without success.
Thanks

Aldo

Never, like Dr JM (décidément !

), except it's héliox 10.

It's still a bit down the road for me, but i can't see why i would be changing dilluent if not in a bail out situation.
Heliox 10/90 would pretty much cover anything i could ever 'dream' up, and would only change to an off board dill, if i had to bail and go SCR...........don't say a word Dr.Mike|!!!

I use 10/52 during the entire dive...

Is there any particular reason you use t/mix as aposed to heliox?

Aah ok, so it's a logistical decision rather than a technical one?
