Auto Sensitivity
Keeps sensitivity at a level that works well under most conditions, reducing the
need for adjustments. You can make minor changes
to sensitivity with Auto Sensitivity turned on, but
you will have to turn it off to make significant
adjustments.
Auto Sensitivity can be turned on/off by selecting
Auto Sensitivity from the Sonar
menu and pressing enTeR .
Colorline
Distinguishes strong sonar echoes from weak
sonar echoes. That makes it easier for you to
distinguish fish or structure from the bottom.
A hard return will be shown as a wide, bright
yellow line, whereas a soft return will be a
narrow reddish-blue line.
To make adjustments, press the
Colorline
softkey and then press the keypad left/right to
select a desired level. Press the softkey again to
return to normal operation.
NOTE: By default, Sensitivity is set to auto mode. You may
have to turn off Auto Sensitivity to set sensitivity to a desired
level. Auto Sensitivity is covered in more detail later in this
section.
