SI is side imaging and looks out to both sides. DSI is down side imaging that produces a nearly picture like image from above. I like the image results from DSI better than the SI, but have wondered whether it is usable to locate fish or just structure.
Often at Lake Powell standard sonar will pick up a blob on the bottom and its difficult to determine what it is. The DSI will give a clear picture of the "blob" tree or otherwise.
