I would concentrate on the deep edges of the flats. They are very easy to see on Lakemaster because the contours are all stacked on top of each other. You will get fish on top of the flats, but they are not up there very long usually. However, when they are up top, they are usually there for a reason…TO FEED!
Some spots on the edges of flats are good for no real reason. They appear to just be the edge, but usually there is more to it. Usually it has to do with Bug Larvae or baitfish.
There is a lot of edges to the flats out there. Using Lakemaster makes it much easier when you are in search of walleye. Of course, points and turns are always popular spots but don’t overlook any edge. Usually the fish are either there or they are not. It doesn’t take to long to figure that out.
