The rows closest to the boat icon at the top of the view are the most recent
sonar data. The information is scrolled down the screen as new data, drawn at
the top of the screen, becomes available.
The side beams operate at a frequency of 455 kHz. It is important to understand
that when the boat turns, the strips to one side will begin to overlap and the
strips on the other side will fan out, providing some distortion to the image.
Side beams look out 240 feet to each side, with a total side coverage of 480 feet,
with a depth limitation of 150 feet, depending on the contour of the bottom.
Your Side Imaging® transducer also provides traditional sonar imaging at
200/83 kHz. Total coverage under the boat is 180°.
