Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
The equipment is fantastic, very intuitive, and easy to use.
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.
Great service. [I replaced/upgraded] unit in aircraft.
Great product. [I chose EI because] you have no competition.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Great product. So easy to read compared to the originals.
[I chose EI because of its] Reputation and value.
I have never had an issue with any EI products… it looks fantastic on the panel.
Very easy to install and directions were straight-forward.
