Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.

Jason Y. from Arizona

 Fantastic customer support!

Jake M. from Arizona
Cessna 172G

Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!

Bill M. from Connecticut

Met all my requirements; great support.

I have worked with your products before and I like them.

David K. from New Mexico

Have had EI instruments in my past plane and current plane and they always performed flawlessly.

Gary M. from California
Cessna 182Q Skylane

Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.

Logan from Montana
Cessna 172B

I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.

Don K. from Wisconsin

Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
