I use my SI solely to find cover. And it is indispensable to me for that reason. I figure a school of suspended open water fish would move by the time I can circle back to it if trolling and it's not very accurate when rigging at slow speeds. I thought DI was great until I realized that it's just pretty pictures. I don't necessarily care what it is that is down there, bus or bush it either has fish or it doesn't. I rarely if ever use it. I am either using SI full screen to from cover or gps/2D on split screen while fishing. Or I'll have my rear unit on full map and my bow unit on 2d. Granted I fish from a stick steer and both head units are on the bow.
