Haven’t used it yet, but we are excited to & Love the way it looks!!
Good engineering support.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
We have other EI products currently and have always been satisfied.
E.I. Always Exceeds Expectations!
