Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

The RPM Isolator Packet contains the essential components required to condition the RPM signal from your Magneto for accurate readings on Electronics International instruments. These isolators are designed to attenuate strong signals that can otherwise cause high or jumpy RPM readings. The kit includes primary ring terminal isolators for the mag switch, along with additional inline isolators to fine-tune the signal strength for various magneto types. This packet is compatible with the R-1, CGR-30P, CGR-30C, MVP-50P, and any system utilizing the EDC-33P.

Good to go! Excellent instructions and easy install. Outstanding instrument!
EI tech support is the best.
The equipment is fantastic, very intuitive, and easy to use.
Works Great! Love it!
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Love the instrument, easy to install, all good
Great product. So easy to read compared to the originals.
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.
Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
Your sales and support teams are very helpful.
