DISPLAY
INTERPRETATION
Now let's look at the display.
First,
we'll turn on the X-40
by pressing
the
ON
key. The
lights
will
flash for six
seconds. The chart scrolls the return
echoes across the screen and the
digital searches for the bottom
depth.
It's flashes 0 untIl it finds the bottom.
Once it finds the
bottom, the
depth is
displayed.
Here the X-40 has
found the
bottom at
48 feet. The
range
is zero
to
80 feet. It automatically chooses a
lower limit
that placesthe
bottom
sig-
nal near
the bottom of the
display.
The bar at the
top
of the dis-
play is
the
sensitivity
bar. It shows
the
sensitivity in use. The bar extends
from left to right. A very short bar
indicates minimum sensitivity. Setting __________________
the
sensitivity
to maximum causes the
bar to run completely
across the
top
of the
display.
The word STOP indicates the X-40's chart is stopped.
Thetopline
ofthe
chart
isalways adashed line. It
movesfrom
right
to left, showing
the chart is moving. As the chart speed increases or
decreases, the dashed line changes speed accordingly. Stopping the
chart causes the
line to flash on and off.
The
range is both an
upper
limit and a lower limit at the
top
and
bottom of the
display,
respectively. In this
example,
the
range
isO -80 feet.

Operation section of this manual. It
explains in detail all of the functions that are in this section, pIus other
features not discussed here.
The
temperature of water in the lake is seldom constant from
top
to bottom. Layers of different temperatures form,
and the
lunction
of a
warm and cool
layer
of water is a
thermocline. The
depth and thickness of
thethermoclinecanvarywiththe
season ortime of
day. In
deep
lakesthere
may be two or more at different depths. Thermoclines are important to
fishermen because they
are areas where fish are active. Many
times bait
fish will be above the thermocline while
larger
game
fish will
suspend in or
just
below it.
The X-40 can detect this invisible layer in the
water, but the
sensitivity will probably
have to be turned up
to
see
it.
A
knowledge of the water
temperatures
various fish
prefer,
and in
which
they usually remain, helps you get
the most from
your
X-40.
SURVEYING A LAKE
The most
successful anglers on
any body
of water are those who
fish it
day
after
day
and
year
afteryear. Eventually, they
learn
the hot
spots
that produce
fish
consistently. They
discover
through experience where,
and at what
depth, they
can
expect
to find the fish
they
want at
any
season.
And
they
realize that
these
productive areas change throughout
the
year
depending
on water
level, temperature,
food, and other factors.
With the
X-40, anyone can eliminate
guesswork and
concentrate
on the areas where fish are likely
to be. Even if ft's the first time on the lake!
The most efficient
wayto
become
acquainted
with
a
body
of water
is to
survey
it with
your
X-40. Start with a
map
of the
lake, if
possible, and
indicate the promising spots
in relation to landmarks on
shore.
As
you go
about
your survey, your
X-40 will tell
you
the
depth
and
type
of bottom. It will also reveal
suspended
fish. Multiple
signals on the
dial usually indicate a
good school of fish and it's worth it to
stop
and fish
for them. You may
not get
any
further.
Keep a few
Lowrance Fish-N-Floats in the boat, ready to toss
overboard. When the X-40 indicates a school of
fish, throw the buoy
out.
The
string will unwind until the sinker hits bottom. Then, because of the
marker's flat shape, it won't unwind any further. With
the school thus
marked, you can make your
turn and come back to fish in exactlythe right
spot.
This is
essential when
you'refarfrom
shore on
a
big
lake. Unless
you
mark the
school of fish when
you're
over it, you may
not be able to find it
again.
