Missed deco stop, lock out?

Discussion in 'Advanced Scuba Discussions' started by scubadada, Sep 21, 2018.

If you miss a deco stop and surface, will your dive computer lock you out?

    Tracking nitrogen exposure and using that for future dive planning has value under any situation. For a skipped a deco stop, that behavior would be applied to any subsequent dive. There may be very large differences between a big deco dive vs. a light deco dive. The calculation of nitrogen exposure over time would still be the major determinate of risk for DCS

    Garbage In, Garbage Out. For example if missing a deco stop results in larger bubbles and larger bubbles take longer to eliminate, then that results in slower off-gassing. Which has to be factored in, or all subsequent calculations are off and all your computed nitrogen exposure over time is garbage.

    So, besides SW and Garmin, which other computers do NOT lock you out?

    How about Scubapro, Sherwood, Aqualung, Ratio, Cosmiq? Looks like us SBers pretty much only use SW, Oceanic and SUUNTO.

    I personally use a Scubapro 330 Bottom Timer.
    It doesn't do anything, including lockouts :)

    Cost me just over a hundred bucks and is still running after 12 years of vigorous abuse.
    I'm happy with it.

    :shakehead: It’s a bottom timer. Not a dive computer.

    Obviously :)
    The point is, the problem posted is solved with a Bottom Timer.
    That's the only reason I brought it up.

    Happy diving :)

    Pretty sure my Oceanic PPX will not lock me out if i miss a deco stop or a deep stop. However my Suunto vyper did

    Your PPX will lock you out in violation gauge mode for 24 hours for a missed decompression stop, see pp 39-41 of your manual.

    The deep stop and the safety stop are optional, there is no penalty for ignoring them, see pp 20-21 of your manual.
