Selecting a Display Mode The CSH-73 provides three display modes: normal sonar pic- ture, echo sounder (E/S) combination, and history display com- bination. 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 th

SEA SURFACE 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.

» Adjusting the Gain The GAIN control adjusts receiver sensitivity (gain). Adjust it so fish echoes are clearly displayed with minimal noise on the screen. Too high a setting not only displays excess noise and makes it difficult to discriminate wanted echoes but also causes seabed echoes to be painted in strong colors, resulting in echoes being masked by seabed reflections. Normally, set the control somewhere between positions “3” and “7”. Gain low Gain proper Gain high Figure 2-2 Gain settings
