Great product. [I chose EI because] you have no competition.
OLC-2 Connector
The OLC-2 eliminates the need for soldering, crimps, and expensive connectors, all while creating a perfect connection between two wires. The two wires are stripped 5/16″ and then slid into opposing ends of the OLC-2. A set screw on each side of the OLC-2 is gently tightened. The OLC-2 can also be used to create perfect connections with Thermocouple wire, which means no more bulky TC connections.

Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.

Nice unit. EI is the best!
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.

I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.

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.
