I agree with several who have already commented that many factors scare the fish. I have witnessed fish be spooky after much pressure on them. I for one cant see myself fishing without livescope. It keeps me from fishing miles of unproductive water. One of the biggest challenges I have had was determining whether I am looking at crappie or white bass. There are times when it seems to more helpful than others. Warning! Livescope can be addictive.
