Question for you guys: How many of you use your depth (fish) finder to find fish? I mainly use mine to find the breaks or where the channel drops off or to try to find structure or baitfish. I don't seem to see fish very often on the river. When I'm on the resevour bass fishing I can see on my screen schools of crappie, I can see bass and catch them. I just dont see very many fish on my finder when I'm on the river. Any info?
