I really like to crappie fish, best fish in the lake for frying IMO, and shooting docks is a mainstay on my lake. Has anyone had success with using Side Imaging to locate fish under docks? I've just started trying it and so far haven't had much luck. I think it may be my settings. If anyone does this please share with me the process. How close to the dock, SI range, only right or left side, etc....This would save so much time if it was possible to get really good images by just driving by and checking out a long line of docks.
