How Sonar Works
SONAR stands for SOund NAvigation and Ranging. Sound travels through fresh water at a speed of approximately 4,920 feet per second.
A sonar device (depth nder/sh-nder) measures the amount of time a burst of energy takes to travel to the bottom and return to the
transducer. This time variation is then displayed on the readout of your sonar. When the depth gets deeper, the time of travel for the
sound increases. The burst of energy, known as the transmit pulse, is generated by the sonar’s transmit circuitry. This burst is delivered
to the water via the transducer. The return signal, known as the echo, is received by the receiver circuit, also via the transducer. A central
processing unit makes the calculations to determine the depth and signal strength of the bottom and other targets.
The sonar signal sent from the transducer will reect, or bounce o of any object that has a dierent density than water. This makes it
possible to detect not only the lake bottom, but also vegetation and sh.
How Flashers Work
The sonar portion of a asher works in the same manner as any other graph or LCD sonar
device. The dierence is in how the return signal is displayed. Instead of adding the data to a
progressive representation of the bottom to construct a history, the data on the asher display
always represents the current point in time, also known as “real time.” The display consists of
a wheel with indicator lights mounted in one location. The wheel is spun at high speed and the
lights turn on and o rapidly to show the sonar readings.
The Vexilar Advantage
Vexilar’s sonar design oers an optimal balance between the power of the transmitted pulse and the sensitivity
of the receiver circuit. Excessive power has been shown to cause premature transducer failure, distortion of the
sonar signal, and possibly spook sh from the audible noise they hear. Vexilar provides a balanced performance
level for a wide range of shing scenarios.

BASIC CONCEPTS OF VEXILAR USE
Vexilar FL/FLX series color ashers are great tools for open water and
ice shing. Once you learn to understand the basic concepts and meaning
of the color display, you can apply this knowledge to greatly increase your
shing success. All the FL/FLX Series ashers can be used for:
• Determining the current depth at any boat speed.
• Locating sh-holding underwater structure.
• Determining the bottom hardness and transition lines.
• Penetrating thick vegetation to see what’s below.
• Finding sh and the bait they feed on.
• Watching your bait and the sh around it.
Range Control
Depth Range determines the maximum depth of water in which the
asher can see the bottom. For example, the shallowest range available
on the FL-18 is 0 to 20 feet. This means that if the water depth is between
zero and 20 feet, the bottom will be displayed on the screen. If the water
depth gets deeper than 20 feet, you will need to select a deeper depth
range in order to see the bottom. It is usually best to select the shallowest
depth range possible to see the bottom. This allows the water column
below to be represented by the greatest amount of display screen area.
This oers the highest resolution and makes things bigger and
easier to see.
Gain Control
Gain controls the amount of amplication applied to the return
sonar signal. Think of gain as your volume control. You turn up the
gain to see more of what’s below. You turn down the gain to see less
of what you don’t want to see. The goal is to nd a gain level that
shows you as much real information as possible without displaying
stray signals of clutter and interference. Keep the gain setting as low
as possible for best overall performance.
Gain can sometimes act eect the total area of coverage below you.
As you increase the gain level, you can see things farther away from
the transducer. This can be helpful when looking for suspended sh,
but only turn it up temporarily as the signal distorts your targets into
big blobs of color. Unfortunately, a high gain setting won’t work in
weedy areas either, because the objects in the center of the cone will
get amplied and overlap anything on the outside, making these
objects impossible to distinguish.
Interference Rejection
This feature rejects sonar interference generated by other nearby
depth sounders. Interference Rejection, or IR, comes on automatically
when you turn the asher on, and you can adjust it further if needed.
See page 6 for details.

5
THE VEXILAR DISPLAY
Each FL series asher display consists of multiple colors
(marks) which appear at various positions on the screen.
Understanding what the colors mean, and the position and
size of the colored marks, is the key to being able to interpret
the information correctly.
RED = Strong Strength Signals. Strong signals are
generally produced by signicant underwater objects such as
the bottom, heavy vegetation and large sh. However, smaller
objects, such as bait sh, can display as red if the object is
directly under the transducer.
ORANGE = Medium Strength Signals. Medium
signals are produced by smaller objects and softer bottom
types. Also, medium strength signals can be produced by
larger objects in the immediate area around, but not directly
under, the transducer.
GREEN = Weak Strength Signals. Weak signals are
produced by small objects, such as light vegetation, bait sh, and
even air bubbles or aquatic micro marine life. Larger objects o
to the sides of the transducer can also be displayed as green.
The Zero mark always shows, even if
the transducer is unplugged. This mark
indicates the starting point. Marks just beyond
the Zero mark can
indicate algae, floating
vegetation, or even “ice
noise” caused by thick
ice conditions.
Bottom is generally
the most prominent
mark on the
display. Bottom
usually starts with
a wide band of red,
with orange and
green trailing.
Read depth here: The current
depth is indicated by the leading
edge of the bottom mark. The
depth is 12 feet in this example.
You read the
display in the
clock-wise
direction. The
farther around
you go, the
deeper the water.
Fish, bait fish, and
even your lure, will
show anywhere
between the Zero mark
and the Bottom mark.
Here, a weak object
shows about a foot
above a much
stronger
object.
Marks beyond the
bottom mark can
indicate either hard
objects within a
soft bottom or large
objects well off to
the side.
Understanding the Display Marks
This is the basics of what you will see on the display.
FLX-28 and FLX-30BB models have additional color options. See page 56 for more information.

INTERFERENCE REJECTION EXPLAINED
The purpose of interference rejection is to reduce cross-talk interference from other nearby depth sounders. This can be very helpful if you have
another sounder mounted on your boat running at the same frequency as your asher. It is also helpful when nearby anglers are running sounders
operating at the same frequency as your asher.
Cross-talk interference occurs when the signals sent from one depth sounder are received by another. If the two sounders’ frequencies are the
same, each unit is unable to dierentiate between its own signals and others. What you see as interference is actually the signals of the other
sounder displayed on your screen. The signals can circle around the display
or remain stable. Beware of the stationary interference signals. They can
lead you to believe the depth is dierent than it is, or that there’s a sh
hanging below you which isn’t really there.
Usually, when you see interference on one sounder, the other sounder will
show it too. Therefore, when you use your Interference Rejection to reduce
or eliminate the interference on your display, the other sounder will see
a similar reduction. This means you can use your Vexilar asher next to
another sounder which does not have the IR feature and both sounders can
run more clearly.
If two Vexilar units are operating together, you will get the best results
by leaving the IR setting at one level on one unit, while adjusting out the
interference displayed on both units using the second unit’s IR feature. Interference occurs when the cone angles of two separate sounders
operating at the same frequency intersect. It can also occur if the
sonar signal from one sounder bounces off an underwater object and is
received by another sounder.

VEXILAR ICE FISHING
The Vexilar FL & FLX series color ashers oer
distinct advantages over LCD depth sounders for the
sport of ice shing. This unique style of shing oers
a stable platform on which to sh. Because everything
is so stable, the only movements below are that of sh.
Additionally, this position allows you to drop your bait
directly down into the center of the transducer’s cone
of sound. This allows you to observe your bait and the
sh on the display simultaneously. You can tease the
sh and see his reaction in real time.
With practice, you will soon be able to judge for
yourself both sh species as well as the mood of the
sh, and whether your lure presentation is working or
not.
Please Use Caution
Before venturing onto the ice to go shing, be sure
you know if the conditions are safe. Check with the
local bait shops and cautiously check the ice thickness
yourself. You should have at least 6" of clear ice to
safely support yourself and your ice shing equipment.

8
SEEING YOUR LURE
The key to ice shing success when using a Vexilar
ice shing system is the ability to see your shing
lure and its relationship to the bottom, structure,
and sh. Ice shing with a Vexilar allows you to
present your lure to the sh. You see the sh on
the display, and you raise your lure so it is right
above the sh on the display. If the sh is hungry,
it will bite. If not, it will react in some way to your
presentation, such as with disinterest or fear. You
can see this reaction on the asher display and
adjust your tactics accordingly.
Setting the gain level correctly is important to be
able to understand what’s going on below you.
Use the lure’s appearance as your reference for
adjusting the Gain Control. Set it so your lure
appears as a green signal. Because the sh are
much larger than your bait, they will appear as
stronger signals. Be prepared to readjust the Gain
Control up and down often, as small position
changes and the condition of any bait attached
will eect the strength of your lure’s signal.
Typical Ice Fishing View
This illustrates a typical panfish
fishing view. As you lower your lure,
you see it going down on the display
while the curious fish rise to see what
it is. When the two signal lines meet,
it is time to be ready for a strike.
Bottom Fish
Several fish are holding near the
bottom. The thin green line right on the
bottom may be a fish just up off the
bottom, as the others are, but some
distance to the side.
Fish
A pair of fish are rising to your lure as it is
lowered. This is a good sign, as competition
can make fish more aggressive.
Lure
With the Gain Control set properly,
your lure will appear as a weak
signal. You want it to appear small
next to the fish which are much
larger.

THE ICE-DUCER®
Vexilar ice shing systems include a special type of transducer patented by Vexilar in 1997 called the
Ice-Ducer®. This transducer style is designed specically for the ice shing application. The Ice-Ducer®
works o the “plumb-bob” theory. When suspended by the cable, the transducer cone is perfectly aligned
to point straight down.
Stopper - The stopper sets the depth of the transducer. It’s adjustable so you can set
the depth according to your preference or conditions. Generally, you want to set it so
the bottom of the transducer is even with the bottom of the ice.
Float - The oat suspends the transducer in the ice hole. You can also use the eye-bolt
included with the Vexilar ice shing system to suspend the transducer. This can often
be the best choice for early ice conditions.
Cable - Ice-Ducer® cable is specically designed to stay exible in cold temperatures.
This exible cable will be more prone to be cut by your line or damaged if not stored
correctly. It’s a key part of the Ice-Ducer®system.
Transducer - The transducer is designed to allow a perfectly downward alignment
while suspended and be able to endure the severe conditions encountered in the ice
shing environment. Dierent cone angles are available to match your shing needs:
9° Pro-View, 12°, 19° and Broad Band (FLX-30bb only). Transducer sizes will vary.
See page 72 for more information.

10
ABOUT TRANSDUCERS
Cone of Sound
The cone of sound is the area the sound waves cover
as they are emitted from the transducer. Generally,
this area is thought of as three-dimensional cone,
such as an upside-down ice cream cone. Actually,
the cone of sound is not so precisely dened. It is
an irregular shape with edges that taper rather than
end abruptly. Additionally, the cone of sound will
vary slightly from transducer to transducer.
Most objects are visible inside the theoretical cone,
but you can also see objects outside the theoretical
angle yet within the side and main lobes. These
objects must be large enough to suciently reect
the sonar signal. Some of these objects can be
things like the face of a sharp dropping bottom, a
large rock, or even a good size sh or tight group of
smaller sh.
Transducer
Side Lobe
Not all of the sound
waves come out of the
transducer’s bottom.
Some sound comes
out the sides and even
the top.
Main Lobe
The main lobe is
where most of the
sound waves go.
They extend out in
all directions, some
sides more than
others.
Theoretical Cone Angle
The theoretical cone angle
is what the transducer’s
specification defines.
This is the area where
the intensity of the sound
waves drop to a specific
point (-6dB).
The FLX-30bb uses a special broad band transducer that oers a wide
spectrum of cone angles that vary with each frequency. The multi-frequency
system has dierent characteristics than the single-frequency transducer
described here. The Broad Band transducer does not have side lobes.

DEAD ZONE
Beam angle has a large eect on the performance of your asher. There is more to it than simply area
of coverage. The correct beam angle to use depends entirely on your application. If you are shing
for suspended sh then you would be pleased with the performance of
the 19° cone. However, if you were going after sh that are holding right
on the bottom along a steep drop-o, you would have better results with
the 9°. This is because of something called dead zone. Dead zone is
an area within the transducer’s cone of sound that is blind to you. The
wider the beam angle, the greater the possible dead zone. The sonar
will mark bottom as the nearest distance it sees. If you are shing over
a slope, it may see the high side of the slope, at the edge of the cone,
and mark that as bottom. The sh that are holding on the bottom on
the low side of the slope will be invisible to you because they are actually
within the bottom signal on your depth nder. A narrower beam angle
will reduce this eect.
Output Power
Your depth nder puts out a constant amount of power, or sound energy. It does not matter where you have the gain level set. Gain simply controls
how much you amplify the signal that is returned from below. Therefore, a narrow beam transducer will appear to be much more powerful than a
wide beam transducer. This is because you are putting the same amount of power into a smaller area. This can be an advantage if you are shing
in deep water or a detriment if you are shing in shallow water. A narrow beam transducer can be overpowering in shallow water. The use of the
LP (Low Power) Mode on your asher, or the optional S-Cable (page 70), will solve this problem.
Remember to not use LP Mode or the S-Cable in depths beyond 20 feet where you will nd that you need to turn your Gain Control up
much higher than normal. This will give a noisy display and make interference from other units much more likely.

BOAT USE
Navigation
The Vexilar ashers are great tools for navigation while boating. The instantaneous readings oer the
ability to identify depth changes quickly. Here are some tips to help you navigate safely.
CAUTION:
• At all times it is critical to know the depth range you have selected in order to prevent running
aground.
• Be aware that although the depth displayed may be deep enough to navigate presently, shallow water
may be dead ahead. Allow yourself plenty of time to slow down if shallow water is encountered.
• If no bottom is displayed, assume the depth is dangerously shallow. It may be deeper than the
selected range, but never assume so.
• Use common sense. Do not trust the asher as the ultimate source of information. Use good
judgment as well.
Bottom Content: Hard & Soft Bottom
The Vexilar ashers are also great tools for determining bottom content changes. The colors allow you
to easily see when the bottom changes from one type to another.
• Hard bottoms will generally appear as a narrow band with color content of mostly red and orange.
• Soft bottoms will appear as a wide band with more orange and green than red.

13
FISHING VEGETATION
The Vexilar ashers are exceptional when it comes
to reading inside vegetation. With proper transducer
choice, the colors will allow you to dierentiate
vegetation from the bottom. Experience will even
allow you to identify sh inside heavy vegetation.
Tips for Reading in Vegetation
• Narrow transducer cone angles will perform
better than wide cone angles.
• Keep the gain setting very low. Too much gain
will make readings dicult.
• Move a boat slowly so you can identify openings
that may hold sh.
Vegetation has grown up
to this point. In deeper
water (beyond several
feet) this is known as the
canopy. It’s where the
tops of the vegetation
spread out.
Possible Fish
Although this red target
could indicate a clump of
vegetation, it could also
indicate a fish just under
the canopy.
Bottom
Bottom will always be the
largest group of red and
orange signals.
Orange within the green generally
indicates thicker sections of the
vegetation. It warrants watching, as
it could also indicate a fish on the
outer edge of your cone.

BOAT INSTALLATION
Mounting the Flasher Unit
Take a few minutes to plan your installation. The unit should be
mounted in a location where it will be readily visible yet out of the
way of trac. The mounting surface should be fairly at. Be sure
to allow clearance for the cables at the rear of the unit so it can be
tilted and swiveled easily. The unit is weather-proof, not waterproof,
so try not to mount it in a location where it will be exposed to the
extreme forces of wave impact during severe conditions.
To Install the Flasher Unit
1. Obtain four appropriate fasteners for your mounting location.
2. Remove the asher unit from the gimbal bracket by removing
the two gimbal knobs on each side of the unit.
3. Position the bracket in your intended mounting location.
4. Mark the four holes and drill each using the appropriate drill
size.
5. Attach the gimbal bracket
using your four fasteners.
Tighten securely.
6. Replace the asher unit into
the gimbal bracket and tighten
the gimbal knobs.
Power Connection
Your asher unit requires a 12 volt power source to operate. A
connection can be made directly to a battery, or a connection can be
tapped into the boat’s electrical system.
• If possible, power your asher using the main starting battery,
not a battery that powers an electric trolling motor.
• When routing the cable, be sure to stay away from, or provide
cable protection around, areas with sharp metal edges.
• If the supplied power cord is too short, extend it using 18 gauge
wire.
• Important: Be sure to have circuit protection, such as a 1-amp
fuse or circuit breaker, placed in the positive line near the power
source to protect the wiring.
To connect the asher to power:
1. Be sure the power cord is not connected to the asher.
2. Route the power cable from the asher location to the power
source.
3. Connect the white or red wire to the positive power source
terminal and the black wire to the negative terminal.
4. Connect the power plug to the asher’s power jack.

TRANSDUCER INSTALLATION
Types and Mounting Methods
There are several dierent transducer types used for the various
mounting options available to you. Choose the style which best
meets the needs for your mounting application.
Transducer Types
• High-Speed Transom: This style is designed to be mounted
externally on the transom of your boat. It has a special wedged
shape to allow water ow when moving at high speed.
• Puck Style: Puck transducers are meant for attachment
to an electric trolling motor. They have a special curved
shape and attachment slots just for this purpose. Pucks are
also commonly used for in-hull mounting within berglass
boats.
Mounting Methods
• Transom Mounted: the method by which the transducer is
mounted externally on the back of the boat. The transducer is
attached at the bottom of the transom with a small portion of it
extending below the hull line (see page 16).
• In-Hull Mounting: the method by which the transducer is glued
to the inside of the hull of the boat. The sonar signal shoots through
the hull and into the water (see page 17).
•
Trolling Motor Mounting: the method by which the transducer is
attached to the lower unit of the electric trolling motor (see page 18).
• Portable Mounting: the solution when easy transducer removal
from the boat is desired. Generally, a suction cup bracket is used to
attach either a high-speed or puck style transducer to the rear of the
boat (see page 19).
NOTE: If you nd that you have purchased the wrong transducer for
your intended mounting application, you can exchange it with Vexilar.
You will only need to pay the retail cost dierence, plus shipping, of the
transducer style needed. Transducers must be in new condition.
Please call for more information: 952-884-5291.
High-Speed Transom Puck Style

TRANSOM TRANSDUCER MOUNTING
Before you begin the process of installing the transducer, check your hull to
nd a spot where you’ll get smooth water ow along the bottom of the boat.
You want to avoid ribs, rivets, and gouges or scratches in the hull. To get a true
vertical depth reading, the transducer should be mounted parallel to the water
line. However, a 10° tilt to either side is acceptable. If the hull is reasonably at
with a dead rise of 10° or less, mount the transducer along the hull bottom. If
dead rise is greater than 10°, mount the transducer with level alignment.
To Install the High-Speed Transducer
1. Assemble the stainless steel brackets to the transducer using the hardware
furnished. Do not tighten until nal adjustments are made.
2. Place assembly on transom at selected location with the front of the
transducer extending 1/2" to 5/8" below the bottom of the boat and with
the front part against the transom. The least amount that the transducer
extends below the bottom is desired. If too low, spray and turbulence will
occur resulting in lost bottom readings.
3. With transducer in place, mark the four slot locations of the mounting
brackets. Drill in center of slot outline using a 9/64" (3.5 mm) drill.
4. Fasten the transducer to the transom using the #10 x 3⁄4" screws, nuts and
washer plates.
5. Before nal tightening of the four screws holding the brackets to the
transducer, tip the rear edge down approximately 1/8" as shown.
6. Tighten all screws.
CAUTION: Do not use any thread locking compound on the
screws. Most products such as Loctite®contain chemicals that
attack and weaken plastics.
IMPORTANT: There should be no gap between the brackets
and the transducer. A wide space between these parts will
cause stress on the transducer mounting ears and result in
breakage with time.
When running the cable to the
sounder, avoid other wiring on
the boat, particularly ignition and
alternator cables. They can be a
source of noise on the sounder
display.

IN-HULL TRANSDUCER MOUNTING
Surface preparation and location are the keys to having a good sonar transducer installation that will last for years, so please take a few extra
minutes to test the location and prepare the surface area. Also, the hull temperature should be at least 60° F while performing the installation.
Select an area in your boat. Ideally, for high speed operation, you will need to place the transducer near the center of the transom area of the boat,
which is often near the drain plug. You must attach the transducer to a solid hull area; this means you cannot have double hull aluminum or a foam
layer in the berglass between the transducer and the water.
To Install the In-Hull Transducer
1. Prepare the surface area. It is critical you nd a smooth, at spot to place your transducer. Small ridges, bumps or even paint under the
transducer will aect the quality of the sonar signal. Your surface preparation kit comes with a Scotch-Bright®pad to smooth any rough areas
down to the base material for a secure installation. Use the pad to rough-up the face of your transducer a little. This will also aid in the long-
term quality of your installation.
2. Clean the area. Use the supplied cleaning patch of isopropyl alcohol to remove dust and dirt from
the target mounting area. Be sure to also wipe clean the face of your transducer. Let dry for a few
minutes.
3. Position the transducer. Place the transducer exactly where you want to install it. Apply the four
supplied positioning pads around the transducer. The positioning pads are needed to prevent your
transducer from drifting o the target area while the A.C.E. adhesive sets up.
4. Mix and apply the epoxy. Follow the mixing directions on the packet of A.C.E. adhesive and apply
the entire packet contents directly to the face of the transducer.
5. Install the transducer. Place the transducer into position. Press rmly and twist slightly back-and-
forth to work out any air bubbles that might have been trapped in the epoxy.
6. Installation complete. Allow the A.C.E. to dry.

ELECTRIC TROLLING MOTOR MOUNTING
There are two main styles of trolling motors: manual steer and electric steer. The proper mounting method depends
on the style of trolling motor.
Mounting to Electric Steer Motors
1. Position the transducer on the bottom side of the motor housing close to the center of the steering rotation.
2. Attach the transducer to the motor using the supplied cable tie.
3. Secure the cable to the lower-most part of the vertical motor shaft.
4. Run the cable through the carry handle on the motor’s steering drive motor. (If your motor does not have this, you’ll
need to come up with an “eye” to keep the cable in place as you stow and deploy the motor.)
5. Secure the cable near the motor’s head at the top of the vertical shaft.
6. Route the cable down through the “coil cord” and out to your asher’s mounting location.
7. Stow and deploy the motor to insure the cable can move freely with the motor, and that it cannot get pinched in any of
the motor workings.
Mounting to Manual Steer Motors
1. Position the transducer on the bottom side of the motor housing close to the center of the steering rotation.
2. Attach the transducer to the motor using the supplied cable tie.
3. Secure the cable to the lower-most part of the vertical motor shaft.
4. Route the cable up the shaft, securing it every three or four inches using cable ties or electrical tape. Be sure to leave a
loop near the section where the two vertical shafts meet to allow for motor rotation.
5. Route along the motor’s mounting bracket and out to your asher’s mounting location.
6. Stow and deploy the motor to insure the cable can move freely with the motor, and that it cannot get pinched in
any of the motor workings.
