EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
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.

Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
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.
