Mine had been beeping occasionally due to a low battery warning (I
have the Senco model offered on Aeromedix.com). I could hear the beep
fine, but it would only beep occasionally. Took me a while to figure
out what it was, actually. But I could definitely hear it fine when it
did beep.

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?
