Ben,

I agree with Jay, the CO Experts unit is excellent. I've had mine for
some time now, I have it in my flight bag in the house as a detector
and then it goes with me in the airplane.

Using it I've found that a number of airplanes have CO in the cabin
but not from a bad heater. The exhaust travels along the belly and
enters near the aft portion of the tailcone. The airflow within the
tailcone is forward, so the CO comes into the cabin. In one of the
airplanes I fly the baggage compartment contstantly has a measurable
level of CO. If the heater and all the vents are off, there is CO in
the entire passenger cabin. With the heater and/or vents on, the CO
is pushed aft and remains only in the baggage area.

Now I'm looking for a way to seal the baggage curtain to keep the air
from the tailcone from coming into the cabin.

All the best,
Rick

I ran into a guy with the cowling off his 182 the other day. He had
gotten one of those units and discovered that his heater was producing
some CO. He was very happy about the ability to measure low levels (not
just thresholds) and move it around the cabin to find where the CO was
coming in.

Oddly his exhaust had pressure tested good (and this is on a freshly
overhauled engine) so just as a precaution he was replacing all the
vent related SCAT tubing.
