Hi All
I get my Evo in july and will do my MOD1 and advanced recreational trimix at he same time
I have been reading the manual as you do
If you have the trimix software and want to to use say nitrox 32 as a diluent can you set your gas mix 32 O2 He 0 N 68 and put the same mix in your bailout or do you have to have both bit of software in the hand set many thanks

The Tirmix version replaces the Nitrox version, you do need to buy both

Yes, you can set the diluent to 32/0/68 on the Trimix version & use as either a diluent or if you go OC. What you have is a gas list of six gases, that can be used as diluents or OC.

But why not use air diluent & let the Rebreather make the loop up to 32%? A question for your instructor

I dont understand why with a Trimix unit that you would use 32/0/68. This seems a waste to me. Sure you would want to reduce the N2 component or else you might as well use air as a diluent.

Sorry if I am missing something.

I'm not Trimix certified but am Advanced Nitrox certified, however to me Trimix is only valuable when diving below 40m.
Using a high O2 mix means that if you need to bail out to OC then you are putting yourself in danger of a >1.6 pO2 situation if you use that mix. This limits your max permissible depth to 40m.
Personally I would be more conservative and run a pO2 max or 1.4 but i know that when s**t happens that you push the limits but I wouldnt want to do that by design.
If I bought the Trimix software (as I might) as and when I buy a Vision for my Classic then I woudl run it in standard mode (a waste I know) or else do my Mod2/3 and use trimix to dive in teh >40m range with full trimix.

Sorry if I misunderstood your original question and confused the issue. I'm still only 1 year into rebreathers ;-) but 16 years of OC does have its uses.

Maybe rocket is thinking of 32% dil as an advantage in an OC onboard bailout situation as long as the profile is within the MOD for 32%... ? -Andy

Hi andy part of my line of thinking is I could hand of my bailout to my OC buddy and he will get the mix he was on the other was not to by nitrox software only be thas out the window thanks rocket
