    BW Technologies GA24XT-M Nice auxiliary warning

    I buy one of these every 24 months. They are accurate (compared with handheld meter) and the alarm can be heard in spite of cockpit noise and noise canceling headsets. Also has flashing led alarm signal.

    In reading the manual I see the battery is replaceable and they are available for less than $5 on ebay.
    I wonder if the calibration is really needed as these are certainly far more accurate than the stick on patches.

    I bought this, and unfortunately, it worked. It alarmed, showing about 15 ppm during initial climb, then decreased to zero during cruise. I have a Cub with an Atlee Dodge hot rod muffler. I suspect exhaust coming in the door. Anyone else with this experience?

    Can someone explain the life cycle of these devices?
    They say 3 years and I see some actually have a built in clock. So will that make them inoperative when the time runs out.

    Smoke detectors work by either a change in ionization or light thru the smoke. CO detectors are chemical, just like the brown dot types. They do quite well lasting as long as they do.
    What's a go-around?

    Yes I had a drager and after 750 days it won't read CO.

    I bought a new one $200 and checked the CO in the cub yesterday. Normal cruise the reading was averaging 12ppm. I pulled cabin heat and the reading went down to 10 ppm, likely due to more flow of air thru the cabin..?

    I reduced power to 1700 rpm, flying tail low at 55 mph for a few minutes and the reading dropped to almost zero at times.....thinking my CO is entering at the tail like MTV mentioned and when the tail drops below the stream of exhaust my numbers come down...not sure. I didn't think of 'standing' on a rudder to see if that would also make a difference.

    I will look into sealing the tail area and see what the numbers do.

    I took the RV8 into Wichita a couple days ago and while taxiing with a tail breeze the numbers came up to 25-30 ppm but once i got to rolling for launch the numbers went to zero and stayed there the entire flight.

    I have this deal in my 180, shows 20 in a hard climb, 14 in cruise but goes away if I open the side vent a bit. Same with the heater on or off, so I ordered a tail pipe extension from Texas Skyways, now I just have to convince myself I can put that round hole extension over the oval tail pipe and get it to seal up without a bunch of tape.

    In the cub I have the CO probe (located under the panel) on the CGR 30 and with the AD Hot Rod exhaust it would show a bit, especially in a climb, changed to Sutton with the longer tail pipe for other reasons and have never had anything above 1 since.

    Are the readings in your 180 with cabin air on or off? What exhaust do you have?

    I had about the same readings in my 180 with stock exhaust. I Pponked and put a new AWI exhaust on and my readings are zero.

    The exhaust is Kinsley and the muffler is pretty new. The readings were cabin air off (it was bloomen cold) and with the heater on or off. Went away with cabin air on about 1/4” of the vent open. There is exhaust staining trailing back from the cowl flap and wrapping up to the bottom of the passenger door making me suspect the door seal. We put this deal on this morning that should get the exhaust further out but it’s too gooey today for a flight. Click image for larger version.

    You have to call them, basically it is an STC’d ceramic coated elbow/extender. You remove it to pull the lower cowl.
