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 360 feet to each side, with a total side coverage of 720 feet,
with a depth limitation of 150 feet, depending on the contour of the bottom.
Please see the side imaging sonar tutorial found on www.humminbird.com for
a more detailed explanation.
Your Side Imaging transducer also provides traditional sonar imaging at
200/83 kHz. Total coverage under the boat is 180°.
