My old man has it for his C120. Works great. NOAA text forecasts are awesome offshore. Sea surface temps help too. You can purchase a subscription for 6 months too for under $200. Great for if you don't fish year round. On occasion it can be a little slow to load the overlay.
Yup, already have the blue prints drawn. Not breaking ground for a year or two. Town was stuck with the bill for rebuilding the drive on dock. Insurance policy was way out of date and only covered about 1/9th of it!
