Understanding the Side Imaging® Display

It is important to understand how Side Imaging® technology produces the display. The images you see on the display are produced using sonar technology. The special transducer projects three distinct beams - one beam facing down and two beams pointing out to the side.

Down Beam is aimed directly below the boat and provides conical coverage.

Side Beams are aimed at right angles to the path of the boat. The side beam coverage is very thin from front to back, yet very wide top to bottom. The narrow aspect (front to back) of the beam illuminates a small strip of the bottom perpendicular to the direction of the boat.

Side Imaging® Representation

As the unit pings, a strip of data is displayed at the top of the Side Imaging® view.

Each time the unit pings, a strip of data representing all the echoes received by the transducer are put together on the display to form the image that you see.

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.
