Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Excellent installation instructions [&] recommend[ed] by others.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Excellent tech help…
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
The layout and quality is impressive.
Good engineering support.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
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.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
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.
