Outstanding Customer Service!!
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Looks great. Works great.

Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
The tach looks and operates amazing. Extremely accurate.
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.

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.
