accurate interpretation of bottom contour and structure. For Side Imaging®, the rock and gravel provide a clearer sonar return than mud and sand because better than downward slopes that face away from the transducer. You can find a for accurate interpretation of bottom contour and structure, including the

Side Imaging® Range - Images shown on the right side of the screen are located on the right side of your boat, and images shown on the left side of the screen are located on the left side of your boat. In this illustration, the sonar is pinging 120 feet on each side.

Shadows result from a lack of reflected sonar from a particular area and can be as valuable for interpretation than the sonar reflected by the object itself. Use shadows to help you see the image in 3 dimensions, oriented in space. You can gain insight into the actual shape of an object, or the depth to which it has sunk into the bottom, through shadows on the display. Objects standing on the bottom cast a sonar shadow. The longer the shadow, the taller the object. Fish also cast shadows. You can use the shadow to interpret how close the fish is to the bottom.

Topography Changes - The light part of the display shows where the beam is hitting hard bottom or rising terrain. The dark part of the display indicates soft bottom (sand, mud) or descending terrain.

NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either device is connected to the Fishfinder. If both devices are connected, then only the information from the GPS receiver will be displayed on the view.
