Excellent installation instructions [&] recommend[ed] by others.
Very happy with our new tachometer!
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
Very easy to install and directions were straight-forward.
Great service. [I replaced/upgraded] unit in aircraft.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Nice bright display.
