Then once you have a grasp of the bottom detail in your head ...visualize the water column separately ...as a semi circle under the boat that is equal to the water depth ...and any target that resides in that "visualized semi circle" will be displayed in the dark water column of the SI image ...


Then once you have a grasp of the water column being a semi circle under the boat equal to the water depth ... Use the shadows on the SI image bottom detail to visualize where that target is in the "visualized semi circle" under the boat ...
