    Another query on this. If there is IP over compensation using an environmental seal and pressure transmitter as you say, then would 2nd stage regs using environmentally sealed 1st stages not free flow at a certain depth due to this over compensation?

    Ok a little bit of a high-jack - but how do you deal with O2 IP on a 150m/500ft dive? yes I do dive that deep (from time to time) so its a legitimate question.

    Plug in rich BO to offboard addition block and use that when below the O2 cutooff depth.

    Just curious how many people use this method for deep dives and how do they rate this method.
    Cheers
