I have a question on the LOWRANCE 9ti elite. It has side imaging left and /or right and down. I have been using down in conjunction with my sonar to help identify fish. My question is on the side imaging. when I am looking at the side imaging chart. I have read you think about it as the line in the middle is your prop wash. Got it. now looking at my screen how is the side imagining to the left and right of the boat looked at? am I looking at it from a top view like I am flying above the boat and looking down and can see the tops of stuff to the left and right of the boat, or am I supposed to look at it as if I jump feet first right off the back of the boat and am standing under the motor on the bottom of the lake and looking to my left and my right?
