What’s on the Side Imaging® Display
(898c SI and 998c SI only)
Side Imaging® displays anumber of easily recognizable featuresthatallow for accurateinterpretationof bottomcontour and structure.ForSideImaging®,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:

reflected by the object itself. Use shadows to help you see the
imagein 3 dimensions, oriented in space. You can gain insight
intothe actualshape of anobject,or thedepth to which it has
sunk intothe 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
