Customer Testimonials

Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.

William F. from Maryland
Mooney M20C Ranger

I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.

Don K. from Wisconsin
Piper PA-28-150

Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

Eric H. from Mississippi
Beechcraft C23 Sundowner

The equipment is fantastic, very intuitive, and easy to use.

Gregory S. From Brazil
Air Tractor AT-502A

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.

David K. from New Mexico

Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
