GRAYLINE°

GRAYLINE lets you distinguish between strong and weak echoes. It

"paints" gray

targets

that are stronger

than a

preset

value.

This allows

you to tell the difference between a hard and

soft bottom. For

example, 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.

you have two

signals of

equal size, one with gray and

the other

without,

then the target with gray is the stronger signal. This helps distinguish

weeds

from trees on

the

bottom, or

fish from

structure.

GRAYLINE is

adjustable.

Since GRAYLINE

between

strong

and weak signals, adjusting the sensitivity may require a
