    Forrest, sensor is the same as the ones in your sidekick, r-22's. Easy to replace

    for those that need CO calibration, if you are nice to your local fire department, and they have a bauer fill station, there should be 0 and 20 ppm CO cal gas along with a regulator on the compressor side of the fill station. That's where I calibrated mine. For a short fix, just exhale into it and tell it that it is 20ppm, you will get some wonky CO readings but it will work

    Why? The CooTwo instructions say 10, 15, or 20ppm.

    You're right, but the link you posted was for 100ppm

    Ah, thanks!

    I am going to send the whole thing back to DiveNav, and have the O2, and CO sensors replaced, and calibrated. They will also update the firmware free. I can research the right bump gas next year.

    Good call. The new firmware is much more useful.

    Sounds like a pain. I'll stick with separate units. Cant beat analox (i know they dont make co anymore) and oxycheq

    Well, you have to understand that I got mine from the kickstarter program, and they have come a long way since then.

    FWIW, I used to have separate units, but tended not to actually use both each time I tested.
