I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
