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

Love my new engine monitoring system.

Tyler P. from Alberta, Canada

Pleasure supporting folks with like values.

Alan J. From Indiana
Cessna 172H

Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.

Todd M. from Ohio
Cessna 195

Great product at a great price …. (and) reliability.

Paul B. from Washington
Cessna 150

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.

Thomas M. from Arizona
Rutan Model 61 Long-EZ

Awesome Product! Great product and fantastic support!

David B. from Texas
Cessna 182Q Skylane

I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.

Charles M. from South Dakota

It works very well; easy operation.

Denis F. from Alberta Canada
