The signals on the

cate an underwater
tree with a few fish
above it. The water is
50 feet deep, the tree
20 feet tall, and the
fish are between ten
and 13 feet deep.
Limbs at various
depths return indi-
vidual signals and ac-
count for the wide
band of
signals on the
dial. Brush

similar, though not so
tall.
Bass and panfish
often hang around
submerged vegetation,
not only near the sur-
face but down to
depths of 25 or 30 feet,
depending
on the
thermocline. To detect
them, anchor bow and
stern so your boat
can't
move. Constant
signals indicate tree
limbs. Signals that
come and go or shift
up and down are fish
— limbs don't move.
When installing
the power
cable,
make certain that the in-line
fuse supplied with the unit is at-
tached to the red conductor of
the power cable as close to the
power
source as possible.
This
will protect both the unit and
the power cable in case either is
ever shorted. A connector is
• supplied
to attach the fuse to the
- power cable.
The positive conductor
in the
power cable is the red conductor.
• The unit is protected from acci-
• dental polarity reversals and no
damage will result if
battery
connections are wrong. However,
the unit will not work.
MOUNTING
The depth
sounder can be in-
stalled in any convenient loca-
tion which has a flat surface.
The adjustable yoke permits
mounting on either a bottom or
overhead
supporting surface. If
the unit is to be located in the
vicinity of a compass, run it in
position temporarily to make
sure it does not affect compass
readings. If
compass heading
• changes, choose an alternate lo-
cation. Note: the unit must be
running
when
you make this
test. Holes
in the base of the
bracket allow wood screw or bolt
mounting.
Thread both knobs partially
into
the mounting bushings on the
case. The gimbal bracket has
slots in the top of it that allows
• the unit to "snap" in without
removing
the gimbal knobs.
These slots will clear the threads
of the gimbal knobs, but net the

spread slighlty to clear the gim-
bal bushings, but will return to
their original position when re-
leased. Holes in the gimbal
bracket align
with the gimbal
bushings on the case and will
not allow the unit to come ofT
even in severe wave conditions.
lb remove the unit, simply
loosen the gimbal knobs, spread
the bracket sides away from the
case, and pull the unit up and
out of the bracket.
TRANSDUCER
INSTALLATION
Two different mounting methods
are available to install your
EAGLE transducer, either
transom mount or shoot-thru-
hull. Although the transom
mount will work on most hulls,
we recommend that the shoot-
thru-hull method be used only
on solid fiberglass hulls. The
transducer signals will penetrate
single thicknesses of fiberglass,
but will not go through porous
materials such as wood or foam.
The signals also will not pass
through
air pockets or voids
in
the fiberglass laminations. Re-
gardless of which mounting
method is used, the installation
should be made in an area that
has minimum water turbulence,
air bubbles, and where the water
is the smoothest.
The transducer cable should be
routed away from other electri-
cal wiring. Do not cut the trans-
ducer cable if
it is too long. In-
stead, coil it and store the excess
in an unobtrusive area. 'frans-
ducer extension cables Model
TEC-10 are available that will
extend the cable 10 feet. If the
