I bought one of the Aeromedix units for $99.

Works great (no I don't work for them, own stock, or any of that other
disclaimer stuff).

Very interesting to watch it operate. In the winter, when you typically
don't have any vents open, on climb-out the unit will start chirping at
about 500' AGL. Mine starts chirping at 10 ppm. Gets up to about 55 ppm.
This occurs because, since no vents are open, there is actually a slight
vacuum in the cabin which sucks in exhaust from the tailcone area.

You have a leak, get it checked out.


If you crack ANY air source, including from the heater itself (i.e., wrapped
around the muffler), the reading goes to "0" in a minute or two. Any vent
source that will pressurize the cabin will do.

Very sensitive. About the only bad thing (if you want to call it that...) is
that you cannot leave it in the plane all of the time. If it regularly gets
"baked" at temps over 120F (i.e., in the spring/summer months if you leave
it in a sealed-up plane) the sensor life is dramatically shortened.

Anyone know if there is any problem in buying a battery operated "home" CO
detector and mounting it under your seat or somewhere inconspicuous? What
is the difference between a "home" unit and an "aviation" unit?

Now before you get crazy and call me cheap...I know that the credit card
pill type is only a couple dollars, but it does not provided an audible
alarm and a problem may go undetected for some time. Any other "aviation"
detector with an audible alarm is near or over 180 smackers. This is in
contrast to a "home" battery operated CO detector that you can buy for 6
to 12 dollars. What is the difference other than one is marketed to
aviation consumers and the other is targeted to home-owners?
