Side Imaging® displays a numberof easilyrecognizable features that allow for accurateinterpretation of bottom contour and structure.For Side Imaging®, the bottom composition determines the intensity of the sonar return. For example, rock and gravel provide a clearer sonar return than mud and sand because of their relative density. Upward slopes that face the transducer reflect sonar better than downward slopes that face away from the transducer.You can find a number of easily recognizable features on the Side Imaging® display that allow for accurate interpretation of bottom contour and structure, including the following items:

8Water column - Shows the relative depth of the water under the boat at a given time. Variations in the width of the water column show variations in the distance to the bottom as the boat passes over.
9Shadows - Result from a lack of reflected sonar from a particular area and can be more 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.
10 Topography Changes - The light part of the screen shows where the beam is hitting hard bottom or rising terrain. The dark part of the screen indicates soft bottom (sand, mud) or descending terrain.

12 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 148 feet |
on each side. |
13 Top of the Display - Information from the side beams are |
displayed at the top of the screen. As new information is |
received, the historical data scrolls down the screen. For the |

1Depth - Water depth; can be set to alarm when the water becomes too shallow.
2Timer - Elapsed time with Speed accessory or GPS Receiver.
3Distance - Distance traveled with Speed accessory or GPS Receiver.
4Average Speed - Average speed reading with Speed accessory or GPS Receiver.
5Barometric Pressure - Requires optional- purchase WeatherSense®
6Temperature - Water surface temperature
7Speed - If a Speed accessory or GPS Receiver is attached, the Fishing System can display the speed of the boat, and can keep a triplog of nautical or statute miles traveled.
