Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.

Larry K. From Kansas

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.

Awesome Tech Support. Like the functions it supports and the fit and look in the panel.

Brian M. from California

Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
