What
is the difference between a "home" unit and an "aviation" unit?

There's a lot of what appears to be useful information at
http://aeromedix.com
under the description of their "CO Experts Model 2004". Of course, it's
not an
unbiased source.

The gist of it is that the home units are typically set to alarm at levels
(75-100ppm?), even though impairment begins at much lower levels. They also
have a 1-minute or longer sampling frequency so they will not react
immediately to changes as you make them (such as shutting off the heater or
opening a window). Aeromedix claims this is useful because it can allow you
to troubleshoot what is causing the CO infiltration more effectively. As
Dave points out, Aeromedix is not unbiased.

My opinion, which is worth every penny you're paying for it, is that the
Aeromedix detectors are probably quite good, and at $180 are perhaps a wise
idea particularly if you fly up high where there's less O2 to begin with,
but if you're not going to spring for it, you're better off with a Wal-mart
unit than the credit card or especially nothing at all.
