Sensitivity
Controls the level of detail shown on the display.
Too much detail will clutter the screen. If Sensitivity
is set too low, desired echoes may not be displayed.
Colorline/Grayscale
Separates strong sonar echoes from weak sonar
echoes. That makes it easier for you to distinguish
sh or structure from the bottom. A hard return
will be shown as a wide, bright yellow area,
whereas a soft return will be a narrow reddish-
blue area.
Sensitivity set
to 65 percent.
Sensitivity set
to 85 percent.
