GRAYLINE®
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
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
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 shows the difference be-
tween
strong
and weak
signals,
adjusting
the
sensitivity may require
a
different GRAYLINE
level,
also. The level chosen
bythe
X-55 at
power
on
is
usually adequate
for most conditions.
Experiment
with
your
unit to find
the GRAYLINE
setting
that's
best for
you.
To
adjust GRAYLINE, press
the MENU
key,
then
press
the
key adjacent
to the "ADJUST
GRAYLINE" label. A screen
similar to the one at
right ap-
pears.
Now
press
theIeft
arrow
key
to decrease the
gray
level.
Press the
right
arrow
key
to
increase it. The
percentage
of
GRAYLINE in use
changes
as
the arrow
keys
are
pressed.
The barchart also
gives
a
graphical
indication
of the GRAYLINE level.
You can see the
change
on the screen
(both
on
the menu and on
the chart
record)
as
you press
the
keys.
After
you've
made the
adjustment,
press
the CLEAR
key
to erase the menu.
FISH I.D.
The Fish l.D. feature
identifies
targets
that meet certain conditions as
fish.
The
micro-computer analyses
all echoes and eliminates surface
clutter,
thermoclines,
and other
signals
that are undesirable. In most
instances,
remaining targets
are
fish. The Fish I.D. feature
displays symbols
on
the
screen in
place
of the actual fish echoes. There are fourfish
symbol
sizes:
tiny, small, medium,
and
large.
These are used to
designate
the relative
size between
targets.
In
other
words,
it
displays
a small fish
symbol
when
it thinks a
target
is a small
fish,
a medium fish
symbol
on a
larger target,
etc.
The
micro-computer
is
sophisticated,
but it can be fooled. It cannot
distinguish
between fish and other
suspended objects
such as
trotlines,
turtles,
submerged
floats,
air
bubbles,
etc. Individualtree limbs
