Selecting a Display Mode The CSH-53 provides three display modes: normal sonar pic- ture, echo sounder combination, and history display combina- tion. Those modes may be selected with the NORM, E/S and HIST keys. Table 2-1 Display mode description Mode Description The sonar picture appears over the entire screen. This mode is useful for detecting and tracking fish schools. The default display area is 1.3 times the range, but it can be changed to 1.6 times the range on "EXT KP/TM DSP" in the SYST

Selecting a Display Range Operate the RANGE control to select a display range. The range selected appears at the top center of the screen. Setting the Tilt Angle The tilt angle shows the direction to which the sound wave is emitted. When the sound wave is emitted horizontally, the tilt angle is said to be zero degrees and when emitted vertically, 90 degrees. To set a tilt angle, operate the TILT lever. R400 Tilt Watch the tilt angle indication at the top right T 15 angle corner on the screen. T

How to discriminate fish echoes from the seabed The figure below illustrates how two fish schools a and b are displayed on the screen using three different tilt angles. Case 1: Tilt angle 30 to 40 degrees. Fish school is obscured by the seabed. Case 2: Tilt angle 10 to 20 degrees. Fish school is located above the seabed (midwater). Case 3: Tilt angle 0 to 10 degrees. Fish school is located close to the seabed. Case 1 Case 3 Case 2 Fish school a Fish school a Fish school a Seabed Fish Seabed
