Side imaging is quite different than typical sonar systems. A conventional sonar system will move from right to bottom, but the side imaging will show move from top to bottom. The most recent reading will be on the upper part of the display while the bottom is the history of sonar readings. Usually, the boat location is at the top middle point.
