I love my livescope you may not limit out everytime you go out, but it will put you on fish. I shot docks all the time, what i don't do now is shot docks that don't hold fish. As others have stated it will change your mind on some things you thought you knew about how crappie act. I have seen fish hit my jig, but that will almost at the boat. Under boat houses and docks i don't see the jig not looking for it. Still in the learning stage, there is so much down there need to learn what is crappie, never thought there was that much down there. I thought if they were down there they would hit, not so.
