I uploaded the Lakevu HD maps last night and was playing around with my local lake, Lake Nockamixon in PA, and it worked. I saw the 1' contours and then discovered the depth shading. After setting up my shading, I went back out to Fishing Chart to look at my work and there were only 15' contours on that lake. Every 15' and zero shading. All the other lakes in the area have the 1' lines and shading except the ONE LAKE I wanted. What happened???

Go back to the Nav Chart instead of the Fishing Chart
