Just wanted to shoot out a quick email to you. I’ve been using the Illyrian you sent in my personal plane and I have to say, it’s pretty cool. I really like it even thought my little plane can’t get up to where it could be a problem. It’s nice to have to demo to folks and I always have my flight bag at work with it attached to my headset.

This morning we launched from Missoula in Miss Montana enroute Normandy to participate in the 75th anniversary of DDay celebrations. Onboard we have an Aithre Shield CO monitor developed by a fellow RV10 builder. We love it, the ability to move it around in our large DC3, read and store results in the app, and have confidence our 75-yr old airplane is safe. Great product.


Just as I was departing to the practice area while keeping an eye on the Shield, it goes red.  That's it, I've got a confirmed exhaust leak.  I immediately pull a tight right to re-enter the pattern while closing the heat control and dumping some fresh air in.   After the flight, I realize I've got a bit of a headache that I know came from the CO levels.  THANK YOU for this wonderful little device.


Aithre has achieved a wicked risk-mitigation solution to the carbon monoxide threat in the everyday general aviation pilot world.  Aithre didn't just talk about future improvements, they did something about it in quick fashion.  When it comes to CO awareness I trust my life and my family's lives to Aithre.

Just a quick note to say what a great product!  I’ve been using it now for a couple of months, and it’s so good it’s picking up the CO levels in the L.A. basin (1 to 4 PPM depending on where and what time of day)!  It was reading the *ambient* CO in the air in L.A. correctly!  Actually, *very* accurately…impressive!
