I recently purchased a fish finder and I have never used one before. My only issue with understanding how to use one is that the one I have projects a two dimensional image. I have a couple questions about this.
My first question is since it only projects a 2D image, do I have to position the transducer a certain way? For example, if I point the transducer north, will it give me the reading of the lake bottom pointing directly north (directly where my transducer is pointing?
If I anchor the boat so I do not move, why does the screen still scroll?
