A great old adage for finding the best part of any ledge is "ends and bends". Look at a long channel break and look for the ends and bends in it. The end of a creek channel where it meets another channel is an example. A bend in a channel break is another. The end of a channel bend is another. All underwater points are obvious. Maybe too obvious. The great ledge fishermen look for subtle ends and bends that don't show on maps. Like liitle bumps or points that stick out on an otherwise straight ledge. They also possess the ability to visualize what is under water, what they are throwing at and where the fish are positioned along the offshore structure. To get started in your search though, keep ends and bends in mind. Good fishing.
