Peace of mind - especially during cold temp flying. Even though my Sentry ADS-B in receiver has a CO detector built in the redundancy of a 2nd source of detection is nice. These are inexpensive and can be placed anywhere in the cockpit.

Nice detector card. Like the one year life. Hope it lasts a year so I can stick a new one on every annual. If it doesnt last a year they are cheap enough to replace.

Richard D Verified Purchase

ASA Carbon Monoxide Detector

Perfect piece of mind.

I purchased one of these for my Toyota SUV that has over 400K miles on it. Weve been using these in our airplanes over the years. They used to be the primary CO detector, now we use them as a backup to the CO Detector on the Sentrys. The Toyota still runs good as ever and I like to have this in the cabin with our two year old daughter riding in there now. It gives me peace of mind.

This is a great device, especially in areas where its sometimes too cold for the electronic ones to work. I remember years ago they had similar ones in the school buses. They shipped it first class mail, so the shipping rate was reasonable. Thank you very much Aircraft Spruce and Specialty Co.

good product

Great product in its own sealed packaging so it doesn’t accidentally come open during shipping.

It’s a simple easy to use safety device, to alert you of a silent killer!

I have had these on my Cardinal. Im no longer flying, but put one on my Toyota.

just what I wanted.

Product as shown and described, fast shipping and well packaged. Would buy again.

x

I use this in addition to having a battery operated Foreflight Sentry CO detector. Just in case the battery dies I then have a simple backup. Make sure you integrate looking at this detector as part of your instrument scan!

Good tool to have in the cockpit.

Great product

As with all products I have purchased from Aircraft Spruce, they are great quality at a very good price. I will keep buying from them.

Twice in my flying experience one of these has saved the day, both times due to an exhaust leak brought in through the cabin heater. Smelled nothing, felt no symptoms, just noticed the dot was turning black. I immediately shut off the heater, opened the cold air vents and landed ASAP. Both times the dot had resumed its normal color by the time I had landed.

Every cockpit should have some sort of carbon monoxide detection.

Great unit thanks

These work as expected.

Ronnie H Verified Purchase

ASA Carbon Monoxide Detector

Works as expected.

Michael L Verified Purchase

ASA Carbon Monoxide Detector

One of these probably saved my life once on a long winter flight. Yawned, by habit looked over to detector, was very dark in color. Shut off heater, opened window and all vents, and landed at nearest airport. Hole found in muffler. Only negative, besides lack of audible warning, is that it must be changed often. Never fly without a CO detector.

Robert L Verified Purchase

ASA Carbon Monoxide Detector

The new detector keeps falling off of the instrument panel. Ill need to get some double sided tape. Otherwise, the detector is OK.

Havent installed yet.

Simple, inexpensive. No immediate alert for spike in CO level.

Doesnt work as quick as the electronic ones, and its sensitive to hot temperatures. For the price though, it does the job.

Though I didn’t expect to use the poorly placed adhesive strip built into the unit, I thought it would at least hold itself in place for a minute while I measured for the improvement I improvised. Why bother putting anything there at all? Save us all a few cents and let us invent our own methods.

Rob B Verified Purchase

ASA Carbon Monoxide Detector

Not bad for what it is. Since C02 will first make you stupid and sleepy before it kills you I REALLY doubt one would notice the darkened spot before the final spin-stall. My last two arrived spoiled. Since my life depends on the thing I decided Id rather have an electronic CO2 detector with an audible alarm and have ditched the stick on things. Dont be cheap, buy a real detector.

Product will probably work fine and indicate the presence of CO in the cockpit alright. But as Ive read in other reviews . . . the sticky tape to hold it in place is essentially non-existent.

Why is the sticky pad so ineffective? I was disappointed in that. Otherwise, its a cheap detector, I assume it works as advertised.

Didn’t last 12 mos as expected - good for about 8 mos

Just good for few months 3-4

These are worth what you pay for them :( short term piece of mind.

Aircraft R Verified Purchase

ASA Carbon Monoxide Detector

Never got to use it. The adhesion strip on the back is paper thin almost ensuring it won’t adhere to anything with any wave. They should make this with a padded adhesion strip and it would accept all situations

Great idea, however the double sided tape that comes attached doesnt stick worth SQUAT!!

TWO COMPLAINTS 1. The tiny strip of two-sided tape thats used to mount the thing is too small to be really effective, and, it wont adhere to the plastic or metals that we have in our single-engine Cessnas and Pipers. 2. There must be a special place in hell for the designers of the packaging. It takes a pair of scissors or a knife to open the package.

Mounting sticker on back does not work. Thing is useless

Michael Verified Purchase

ASA Carbon Monoxide Detector

I ordered two detectors. Both detectors arrived in a sealed package but indicated carbon monoxide. I opened the package expecting that the indicator would turn white once exposed to fresh air but neither cleared. It costs more to ship them back then it cost to purchase them.
