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
Helps distinguish fish or structure from the
bottom by showing hard returns as light colors
and soft returns as darker colors. A lower colorline
setting will display only the hardest returns,
shown in light colors.

Auto sensitivity

Keeps sensitivity at a level that works well under
most conditions, reducing the needs for adjust-
ments. Auto Sensitivity is turned on by default.
