I have a Lowrance 9 touch. I was going to update my Navionics chip, but started looking at the C-Map. The relief shading looks really nice.
I THINK the shading works on my graph, but wanted to check with others to see if that was true??
Also, the Tennessee one states it has KY. Lake. Does anyone know if it has just the area in Tennessee or all of Ky. Lake, and does it have Barkley Lake?
