Keep it up. I’ll keep coming back.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.

The CGR-30P is a fantastic product and EI has excellent customer service. EI is the leader in engine monitors with a strong track record.

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

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.

EI tech support is the best.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
Love it!
