a one inch hole.
Therefore,
after
drilling
the
hole,
pass
the transducer
SURVEYING A LAKE
connector
up through
the hole from under the dash. Then
drop
the
power
cable down from
the front side of the dash. Slide the bracket
over the
hole,
then route
the transducer and
power
cables out the
slots
in the bracket.
Finally,
fasten
the bracket to the dash.
POWER CONNECTIONS
The
Magna
works from
a
12
volt DC
system only.
For the best
results,
run
the
power
cable
directly
to the
boat's
battery. Keep
the
power
cable
away
from other boat
wiring, especially
the
engine's
wires. This
will
give
the
best isolation from electrical
noise.
If
the
supplied
cable is
not
long enough
to reach the
battery, splice
#18
gauge
insulated wire
to it.
You can attach the
power
cable to an
accessory
or
power buss,
however,
you may
have
problems
with electrical interference. See
page
26 for more
information on electrical noise.
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
Magna,
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 Magna.
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
Magna
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
Magna
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
Magna
to 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.
