The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.

[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.

Works great!

Ronald C. from Colorado

Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
