Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
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.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
Nice unit. EI is the best!
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Very happy with our new tachometer!
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
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.
Beautiful graphic display, easy to use, perfect automatic dimming!
Works great!
