I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Great product. [nothing else] can compete.
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.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
