Grayline
Grayline lets you distinguish between strong and weak echoes. It
"paints" gray on targets that are stronger than a preset value. This al-
lows you to tell the difference between a hard and soft bottom. For ex-
ample, a soft, muddy or weedy bottom returns a weaker signal which is
shown with a narrow or no gray line. a hard bottom returns a strong
signal which causes a wide gray line.
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. Experiment with your unit to find the Grayline
setting that's best for you.
