I recently bought a humminbird 598 and for the life of me I can not determine what is fish and what is not. Really the only thing I have been able to determine was a couple bait balls that i seen. I just cant tell difference between fish and what may be just clutter. Does anyone have a unit similar to this that can show me what I should be looking for while on DI and SI. I would greatly appreciate any help I can get.
