Comments about Navionics Navionics HotMaps Premium Lake Maps:
The contour lines are hard to see from a little distance away. I am running it on a HDS 5 on my bow. Hopefully there's a way to change the color of the lines... Other than that this product is wonderful! I bought it for the Sturgeon Bay HD map which includes Little Sturgeon as well! I found a lot of new structure I never new existed. This would work better on a HDS 7 or larger display.
