I just bought my second Standard Horizon. The first was a CP150 monochromatic screen with external antennae. I sold it with the old boat. So I just received my new CP180i and I have yet to install it but it looks very nice out of the box. Can't wait to get it mounted in the new boat!
My experiences with the CP150 were all positive. C-Map Bizer card slid right in and provided me all the buoys and marinas with phone numbers and so much more. Great purchase!
DO NOT BUY CP180 at a store! Shop online an save huge money. I saved almost $300 Check out
