Last week my Aero-152 detected CO in the cabin, and displayed as high as 6 on the display. I have found the problem (exhaust flange leak, and firewall not
totally sealed) and got it fixed.
Thank you,

Dear Sir,
In the last edition of "Consumer" which I received, you have as recommendation to get the AIM 95 or equiv model as the only portable/digital reliable CO
detector around. I have to disagree. I had done a review on the AIM 95 and at first gave it a good rating. Over the next few months I have had three units fail
and go into permanent alarm mode, even whilst flying. What triggered the alarm was a relatively low CO level associated with gear retraction and lowering.
Whilst it caused me to clean up some leaks in the plane, the AIM 95, which is specifically sold as the aircraft model is way too sensitive and has no way to
shut off alarms. The model you indicate, the 696 may be a standard household unit and in that case is set to 100 ppm and again has no way to disarm it.
The aircraft unit will trigger at 20ppm or thereabouts and appears not to like hot weather (more sensitive 80 deg F) as all three of my units have now failed
and I have finally got rid of them.
At Arlington EAA I found the CO Guardian, manufactured by CO Guardian LLC out of Tucson, Arizona, http://www.coguardian.com, and obtained one unit
from Ash Vij, the President. It is now a permanent installation in my 210 and has a varied level response with different colors at lower levels, going to an
auditory alarm at danger levels. Even if triggered at a high level in the alarm it can be disarmed by pulling the breaker as the installation recommends a
unique breaker, safer than an on/off switch. Flying with this installed I have peace of mind and no false alarms. It runs a test cycle on every start up. The AIM
continued to beep (loud) through three days of camping at Arlington, heard even through being buried in some clothes in the back of the plane. You may
wish to check out and review the CO Guardian, I am extremely pleased with the unit and had it installed before two treks to the north this year with our
touring company.

Dear Rosa and the team at Co Guardian,
I thought you would like to know the new unit you sent me works well.
The other day it started to register 130 ppm so I landed to check and found a fault on the exhaust manifold.
This has now been repaired and if had not be for the Co Guardian I may not have known until it was too late!
Thank you and best wishes

Ash, I would like to thank you for making such a wonderful product and backing it up with customer service that is second to none. I have had a CO
Guardian 252F in my airplane for several years. Last week my wife and I were flying to Florida when our CO Guardian started beeping. At first the alarm was
only for trace amounts of carbon monoxide, but after an hour the numeric indicator had creeped into the danger zone. I landed and after a an hour search
found a hole in the exhaust pipe where the EGT probe had been. The CO Guardian identified a carbon monoxide leak that would likely have not even
registered on a less sensitive detector. As a result, it may have saved my wife and me from an ugly accident. Thank you again,
Matt Hapgood
Last Fall while assisting another pilot who was repositioning his aircraft, I needed some heat. When cabin heat was applied, the detector alerted me to an
otherwise undetectable problem. I shut down the cabin heat and opened all the fresh air vents and windows. The detector then indicated a normal condition.
When back on the ground the A&P checked the condition of the exhaust system, now being advised to demonstate great suspicion, he found an almost
undectectable crack. This problem was warned of and successfully relieved only because of the timely warning provided by your device. I have flown with
the little dots. I find them useless. Your device works flawlessly and without any monitoring on my part. Nice going.

I thought you would like to know your Aero-152 unit may have saved us possibly twice. The first time was last October on a cold trip at 8000 FT, the alarm
sounded. At first it was thought to be a Palm making some king of reminder but we soon saw the light on the detector and found that there was a problem.
The ship replaced the "collector" and for a while all problems seemed to have been fixed. Then in April the alarm was heard again. This time it was the rest
of the muffler (which probably should have been replaced the first time). I would expect there was a real risk of more serious consequences if there had not
been a audible alarm.

Ash,
It was good speaking with you earlier about the carbon monoxide entering my new Columbia 400 through the newly certified air conditioning system.
Specifically, I got the CO alarm climbing through 10,000' in normal climb, while using the air conditioning. We aborted the flight and returned to the airport.
After a normal inspection of the firewall, we carried a portable CO detector on the next flight. Same outcome: we had a climbing level of CO while the air
conditioning was turned on. When we turned the a/c OFF, the CO level began to decrease.
However, when doing stalls, we got a large amount of CO, with the max being 245 PPM, this time without the a/c even being on.
After that flight, the Lancair company test pilot flew the plane, and got levels in the mid 150 ppm range.
I returned to my home in TX without the Columbia 400, as the factory continued to "scratch their heads".
I hope we haven't got a design problem with the new air conditioning systems.
Thanks,
Bill Orcutt
