Founded in 1965, Vexilar, Inc.
has a long history of bringing revolutionary technology to
the sport fishing industry. Just some of the Vexilar firsts
include: the first liquid crystal display, the first fish alarm,
the first three color display, and the first CRT and straight

107 Pro Operation Manual
GENERAL DESCRIPTION
The 107 Pro incorporates an extremely high quality
sonar circuit with an easy to understand interface. The unit
is designed to be effective and easy to use. All the main
functions are only one button away. Range and Gain controls are selectable as fully automatic or easily controlled
manual modes independent of each other . Internal battery
backup saves all selections upon power off.
The output frequency of 107 KHz is much lower than
most depthfinders of today. This is designed to give more
output power and a greater area of coverage. The 107 Pro
can truly "arc" fish and does not need to use artificial fish
symbols.
The 107 Pro incorporates Clean Line circuitry that can
"clean out" the harder targets. The bottom, rocks, and dense
weeds are made transparent so fish are more visible near
them. On a hard rock or gravel bottom, fish on the edge of
the cone angle can actually be seen within the bottom signal. And with a 38˚ cone angle, you can cover allot of area.
There are three Zoom Zones which let you hone in on
the area you want to see best. You can zoom just the top
half, middle, or bottom half of the display. These features
are easily activated by a single press of a button. Switching
back and fourth is quick and easy.
Speed and Temperature sensors are included. Two dis-
2
play modes provide a standard graphic view mode or a
digital mode which includes a temperature graph. There
is also a trip log feature to help keep track of the distance
you have traveled.
There are more featur es, including pr ogrammable bot-
tom alarm, fish alarm, a high speed vertical mode, and a
Clean Echo feature to eliminate interference
All told, the 107 Pro is a powerful tool for visualizing
structure and fish, in almost all situations. Quality construction and superior product support. Long Vexilar traditions that go with this unit, and everything else we produce.

INSTALLATION
You will need to find a place to mount the 107 Pro that
will make it easy to view and reach. You must provide the
unit with power and mount the transducer and sensor
assembly in an effective location.
MOUNTING THE UNIT
Find a convenient place to mount the unit. This may
include a boat seat, deck, dash, or a portable case. Make
sure that there is plenty of room for the unit to tilt freely
without the cables binding or stretching behind the unit.
Once you have found the spot, remove the unit from the
gimbal bracket. Securely attach the bracket to the mounting surface. The screws provided are 5/8" long and ar e for
wood/carpet or dash mounting applications. An optional
removable swivel bracket is available.
CONNECTING POWER
Plug the 3 pin connector into the back of the unit. Find
the closest source of 12 volts and route the cord to it. Keep
the cord away from sharp metal edges and avoid tight
places where the cord may get crushed. Connect the white
wire to positive and the black wire to negative. If the cord
provided is not long enough, more can be added. Use 18
gauge wire minimum. Install the included 1 amp in-line
fuse, placed in the positive line, as close to the power source
as possible, to protect against shorts in the wiring.

MOUNTING THE SENSOR BOX
The sensor box needs to be located within three feet of
the main unit. It is recommended that it be fastened to a
sturdy surface. You can mount it, using the screws provided, to a flat surface or you can simply tie it to a frame
or wire harness, using cable ties which are not provided.
The sensor box is weather proof, but be sure to keep it out
of an area that may fill with water.
ASSEMBLING THE TRANSDUCER
Locate the transducer, and bracket hardware. This
includes;
1 Transducer
2 Angle Brackets
4 Bracket Screws
4 Washers
4 Nuts
4 Mounting Screws
Attach the bracket to the
transducer as shown in Figure 4. The flanges of the bracket normally point outward, away from the transducer. If
mounting space is tight, you can reverse the angle brackets and face the flanges inward.

Figure 4
ATTACHING THE SENSOR ASSEMBLY
The speed and tempera-
ture sensor assembly attaches to the transducer as
shown. Pinch, or squeeze,
together the tabs at the top
of the sensor and slide the
assembly down into the
tracks on the back of the
transducer. Push it down
until it stops, and then, push
the tabs back outward until
the catches snap into the
holes on the transducer.
ALTERNATE SENSOR MOUNTING
If you plan on mounting the transducer inside the hull
of the boat or on an electric trolling
motor (described on page 11) you
will need to use the provided sensor mounting bracket, instead of the
transducer to mount the sensor.
CAUTION - It is a good idea to restrain the speed wheel
from spinning freely while trailering the boat. Damage may
result because there is no water to lubricate the wheel bearings. Arubber band works good for this.

MOUNTING THE TRANSDUCER
The 107 Pro transducer is designed to be mounted on
the transom of the boat. The shape will allow a clear depth
reading at any boat speed, if properly installed.
Locate a spot similar to the one in figure 7. Keep in mind
that you need clear water flow across the face of the transducer to insure a clear reading at all speeds. Stay away from
rivets, ribs, or strakes that would be just in front of the transducer. They will disturb the water and scramble the reading. Attach the mounting bracket to the transducer and
hold it up to the boat where you are planning to mount it
(see figure 7).
Mark the four holes on the transom, or mounting plate,
8
Figure 7
so that when the bottom of the transducer is flush with the
bottom of the boat the holes are located at the bottom of
the bracket slots. This gives you room to "fine tune" the
position of the transducer and optimize your reading after
you've put the boat back in the water. Drill out the holes
and install the transducer bracket assembly. Tighten the
screws down securely. Be sure to seal any holes drilled into
the transom with silicone to prevent water from leaking
into the boat.
Route the transducer cord up to the unit taking the
same. care as you did when you routed the power cord.
Make sure that the cord is restrained and not allowed to
flop around in the wind. This can cause stress on the wire
inside the cable, and possible breakage. Plug the transducer
connector into the back of the unit and screw the retaining
ring down tight.
After you have put the boat back in the water confirm
that you can maintain a bottom reading at all boat speeds.
If not, loosen the bracket screws and tilt the transducer
some more. Keep the front edge flush with the boat, but
drop the back edge down a little more. If changing this
angle several times does not clear up the reading, loosen
the mounting screws and slide the transducer down, slightly. Repeat these adjustments until you get a clear reading.
Finally, make sure that all mounting screws are tight.
Fill any gap between the transducer and the hull with
silicone to prevent a rooster tail from shooting up behind
the boat.

PORTABLE MOUNTING
An optional suction cup bracket can be
used to temporarily attach a transducer to the
transom or side of the boat. The cups should
be placed in a location where they will not be
torn off when the boat goes high speed, but
still just low enough to maintain the high speed reading.
The optional BK0044 suction cup mounting plate works
well for this application.
An arm assembly that clamps to the transom or side of
the boat can also be used to hold the transducer. Simply
attach the transducer to the end of the arm using cable ties
or tape. If the arm is constructed of metal tubing insulate
the transducer from the arm by wrapping electrical tape
around the arm. This prevents "ringing" which can be displayed as noise near the surface.
IN-HULL MOUNTING
Finding the best location for the transducer before
mounting is critical. Choose a flat smooth spot near the
center of the bilge and near the back of the boat. It is a good
idea to make a "test run" before you permanently install
the transducer. This makes sure that you can, indeed, get
a reading through your hull, and when the boat is on plane.
Put about a half inch of water in the bilge and hold the
transducer in the intended location. Move the transducer
around until you get the best reading. Mark the spot.
To install the transducer , clean the spot of mud and oil.
