Thread: Interpreting sideimaging

Ive never owned one...but will soon. Of the dozens of photos ive seen of the humminbird sideimaging units I find myself confused on how to "look" at the screen. For instance, the black strip down the middle. I know this is water...but is that water on each side of the boat or under the boat? If thats water to the right and left of the boat then I should tilt my head to the left to see out to the right...and tilt to the right to see out to the left? Right? Wrong? And if thats the case....wouldnt it be better if the screen scrolled across rather than up and down?? Is the water closest to the boat on the outside edge of the screen or inside? Im really struggling trying to figure this out...and I cant find anywhere that explains it. I see plenty of talk about map cards..laptops, networking, PC cables, etc, etc...but never how to actually interpret the screen for a beginner. Maybe Im just too much of a beginner on this...but could someone fill me in?
