I'm getting into Ledge fishing and deep water fishing, but what's the best way to find the spots to fish on your gps. I get the waypoints plotted before I go to the lake, and then whats the best way to fish the exact point or ledge you marked on the gps? That may sound kinda confusing, but i've had trouble in the past with staying right on the underwater point,ledge or hump. I use the GPS on my console to navigate so I don't have a gps/sonar combo on the bow. What's the easiest way to stay on that waypoint the whole time and check to see if it's productive?
