Beautiful graphic display, easy to use, perfect automatic dimming!
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Installation was straightforward; great quality all around.
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
We chose your product because of the great support and reputation your company sustains.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Customer Service is far superior… with an excellent record of resolving … technical issues.
Great product. So easy to read compared to the originals.
