Very impressed with the clarity and readability of the CGR-30P gauge.
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
Great Service.
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.
Fantastic customer support!
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Great product, frees up space
Works Great! Love it!
Beautiful graphic display, easy to use, perfect automatic dimming!
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
Great system and great benefit having everything in one place. Love it.
