Grayline scroll bar.
If you have two signals of equal size, one with gray and the other with-
out, then the target with gray is the stronger signal. This helps distin-
guish weeds from trees on the bottom or fish from structure.
Grayline is adjustable. Since Grayline shows the difference between
strong and weak signals, adjusting the sensitivity may also require a
different Grayline level. The level chosen by the sonar unit at power on
is usually adequate for most conditions. Experiment with your unit to
find the Grayline setting that's best for you.
To change the Grayline level, repeatedly press
MENU
until the
G

scroll bar appears.

to increase Grayline,
↓

screen will show the effects of the Grayline adjustment.
If you reach the maximum or minimum level, a tone sounds alerting
you to the limits. Press
PWR
to clear the menu.
