    I'm shopping around for dive computers and have a quick question that I haven't yet found in the manuals...

    When you turn on the Perdix AI, what is the default gas mix setting? Is it the same as the last time you used the computer, i.e., if I dove EAN 32 last week does it come up the same, or reset to air?

    I typically dive the same mix over and over again, whether it's an hour or a month between dives. I've been burned by other computers that reset the mix after some non-diving interval.

    It stays on your last-entered info, just like it should!:)

    Last active gas is what it stays set at.
    Whatever you used the last time is always what it defaults to on turn on.
    Nice thing is you can set up your gases, then switch them on or off at will.
    So an easy, quick, switch if your last active gas is not the one you are diving with now.

    Recreational computers resetting gas mixes behind divers' backs might be the number one cause for lock-outs on liveaboard trips, truly an awful idea!
