Check this out, I have been using it since last duck season and it is UNREAL! I know a lot of you guys use actual contour maps and lake bed maps, and this wont show you that...but as far as pure navigating....this is the best I have ever seen.

Im not sure what all areas they have incorporated into these maps, but Im sure they can tell you if you call em.

Just wanted to share, its helped me tremendously in coastal navigation.
