So I bought a unit with C-Maps. I just hooked it up and checked a few lakes and was non plussed by the contours. The coast had nothing, ok it’s inland lakes, so I checked out Okeechobee and the contours are in like 3 or 6′ intervals?
So do I need to buy a chip for decent contours? I was also supposed to see Navionics as an option in the settings, I thought it was either or. But navionics is the same, the contours are lacking.
