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.
