The x135 is a very good unit. It has high resolution which helps in marking fish. Personally though, I would spend an extra $100 and get a 102C and not the X135. I put a 102C on my dash and one on the bow this year and all I can say is, I NEVER want to go back to grayscale. The color has shown me fish that I would have interpreted as just a bump on the bottom with any grayscale finder. IMO the 102C is worth well more than the $100 diference.
