    Post Trimix calc

    Hey,

    Could someone help me with calculating my trimix mix. I am so bad with these. My answer was 14/47 but I am not sure if it is correct.

    depth 90m
    1 ATM / 10m
    p.p. O2 1,4
    narc O2 = narc N2
    narc H2 = 0,24
    END 40m

    14 / 47 is correct acc. Vplanner but i'ld recommend 14 / 55 which correponds to END 30m.


    I'm not good too but I think Vplanner is a good investment.
    There's also other cheaper or free calculators available on the net.
    Most offer also smartphone apps.


    By the way, welcome to rebreather world.

    I use CCR mixer when playing with mixes, good little app. Also run ddplan on my phone too. Both free.

    Hi,

    For 90m dive, Tx 14/47 or 14/55 is a bit too much o2 for ccr diving...
