I really like the one I got from Aeromedix. It has a memory feature which I
check before every flight. The highest previous reading, how long ago it
occurred, and how long it lasts are displayed. CO is most likely to show up
slowly as an exhaust system crack or other problem develops. We get a pulse
of 30 many times when the engine starts and exhaust swirls around the
motionless plane but it last 0 hours. If there is ever any change in this,
I'll know to start checking the exhaust system.

I'll try to remember to push the test button the next time I fly and let you
know if I can hear it.

Anyone try any of those battery powered carbon monoxide detectors I see in
pilot shops for about $50. Are they worthwhile? The reason I am asking,
is
that I'm wondering whether it is possible to hear one go off with headsets
on in a relatively 'noisy' G.A. aircraft? Recommendations?
