SURVEYING
A
LAKE
The most
successful anglers
on any body
of
water
are
those who
fish
it
day after day
and
year after
year. Eventually,
they
learn
the
hot
spots that
produce
fish
consistently.
They discover
through experi-
ence
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-25, anyone
can
eliminate guesswork and concentrate
on
the
areas where
fish are
likely
to
be.
Even
if
it's
the
first time
on
the
lake!
The most
efficient
way
to
become
acquainted with
a
body
of
water
is
to survey
it
with your
X-25.
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-25 will tell you
the
depth and
type
of
bottom.
It
will also
reveal suspended fish.
Keep a few
marker
buoys
in
the
boat, ready
to
toss
overboard. When
the
X-25
indicates
a
school
of
fish, throw
the
buoy out. With
the
school
thus
marked,
you can make your turn
and
come back
to
fish
in
exactly
the
right spot.
This is
essential
when you're far from
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.
BAIT
FISH
The
importance
of
bait fish
to
successful fishing
can't be
over-empha-
sized. They are
the
principle food
of
all game fish
in
most waters.
Bait
fish
are
the
plankton feeding
forage
fish,
such as
minnows and
shad. Bait
fish can
also
be
the
young
of
game fish,
such as
crappies,
bluegill,
and
bass.
Most
bait
fish
concentrate within
five feet
of the
surface
where sunlight
promotes
the
growth
of
the
plankton
on which they
feed.
One
method
of
fishing
is to use
the
X-25
tQ
find
the
bait fish first. With
the
Fish ID
feature off,
a
school
of
bait fish will look
like
a
"cloud" on
the
display.
Usually, game
fish will
be
nearby,
often directly
beneath
the
school of
bait
fish.

SPEED/TEMPERATURE
SENSOR
INSTALLATION
(Requires OPTIONAL LST-T Speed/Temp Sensor)
Mount
the
speed/temp
sensor on
the
boat's transom
in
a
location
where
the
flow
of
water
is
the
smoothest.
There should be
a
minimum
of
turbulence and air
bubbles in
the
chosen
location.
The port
(left)
side
of the
transom
is
preferred, however,
the
starboard
(right) side
can be used
if
necessary.
Do
not
mount
the
speed
sensor
behind
strakes,
ribs,
or
thru-hull
fittings. These
will
disturb
the
flow
of
water to
the
speed sensor. In
a
typical
installation,
the
speed
sensor is
mounted
six
to
twelve inches
from
the
centerline
of
the hull. The
sensor must
always
be
in
the
water
to
function
properly.
Make
certain
the
chosen location
is
in
the
water
even
at
high speed
or
when the
boat is
on
plane.
Once you
determine
the
proper
location,
place
the
sensor
on
the
transom.
Make
certain
the sensor's bottom is flush with
the
bottom of
the
hull. Mark
the transom
in
four
places,
two
in
each
slot. Drill a
5/32"
mounting hole
at each
location.
Mount the sensor
to the
hull
with
four #10
stainless steel
screws (not
included).
Use
a
good grade of
caulking compound
to
seal
the
screws.
Adjust the sensor so
it
is flush
with
the
bottom
of
the hull and
tighten
the
screws.
If
the base
of
the
transom
has
a
radius,
fill the gap
between
the
transom
and
the
sensor
with
caulking compound.
This will help
insure
a
smooth
water
flow.
Route
the
sensor cable
to the
in-line connector on the
X-25's power
cable. The
speed/temp
sensor
is
now
ready
for
use.
