On a small lake I've fished for years, I always noticed a tree on one bank that someone had painted a 6" circle with red paint years ago. I never gave it much thought until I realized someone had painted this red dot to line up this spot with other markers on the shoreline as a way to locate a fish holding area. Triangulation is nothing new. Some writers have said American Indians used this method hundreds of years ago, as a way to mark productive fishing spots. If I'm understanding this correctly, once you catch fish in a certain spot, line up with three objects on the shoreline. These can be anything. Pick something to your right, to your left, and directly in front of you. Figure the length of your cast to reach the triangulated spot, and try different depths in the water column. If your limited to bank fishing, or fishing a lake where boats are not allowed, it would pay to learn to do this. There's something down there that consistently holds fish. You may never know exactly what it is, or why the fish hang around this area, but there's some structure or objects in this area that they like. It's an old school way to locate productive spots, and by " triangulating" these areas, you can keep these spots locked in for future fishing trips, and hopefully help your catch rates improve along the way.
