That's what led me to a domestic CO detector that is right for my aircraft and that I have a high level of confidence in.
The basis of Mike's criticsm of domestic CO detectors is they have an alarm threshold of 70ppm after 4 hours, which he says is too high and I don't disagree.
That high alarm threshold may be true of all domestic CO detectors sold in the US, I don't know, I haven't studied their specifications. But it's not true of the domestic CO detector that I have in the RV, nor is it true of any CO detector that complies with the European standard, which will alarm at 50ppm after 60 minutes or at 300ppm in less than 3 minutes. Certainly more sensitive than 70ppm after 4 hours.
My CO detector is designed for mobile use (boats, campervans etc) so it's robust and a much better alternative to the black spot type. For less than $50 I think a domestic CO detector with appropriate alarm thresholds presents a compelling safety argument for renters or owners not wanting a panel mount.
Coincidentally, the CO detector in my RV alarmed for the first time today. The engine was not running at the time. I was about to take an aircraft mechanic for a local flight and as he was climbing into the passenger seat the CO detector chirped twice. He had just come from ground running a radial engine and I'm assuming he brought a cloud of CO along in his clothes. That's sensitive enough for me.
