GRAYLINP
GRAYLINE lets
you distinguish
between
strong
and weak echoes.
It
"paints" gray
on
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
boftom 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
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 showsthe difference between
strong
and weak
signals,

the
sensitivity may require
