About Fla she rs
Established in 1960, Vexilar, Inc. has been a leading innovator of marine electronics
in the sport fishing industry for over 45 years. Some of their innovations include:
SONAR stands for SOund NAvigation Ranging. Sound travels through fresh water at a
speed approximately 4920 feet per second. A sonar device (depth finder/fish finder)
measures the amount of time a burst of energy takes to travel to the bottom and return to
the surface. 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 of bottom, as well as
other targets.

With the recent introduction of the Edge family of liquid crystal sounders, they bring
the first true dual frequency/dual transducer sonar systems to the sport fisherman. The
FL series three-color flashers continue to lead the way in real-time high definition flasher
performance. Quality products backed by world leading customer service are the
bedrock of Vexilar, Inc.
How Sonar Works
The sonar signal sent from the transducer will
reflect, or bounce off of any object that has
a different density than water. This makes it
possible to detect not only the lake bottom,
but also vegetation and fish.

How Flashers Work
The main sonar portion of a flasher works in
the same manner as any other graph or LCD sonar device.
The difference 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 flasher
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 off rapidly to show
the sonar readings at the proper locations.

The Vexilar Advantage
A Long History of Vexilar Products
2
Vexilar’s sonar design offers 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” fish
from the audible noise they hear. Under-powered systems lack the ability to provide good
resolution and target distinction. With a well designed system of transmit power and
receiver sensitivity, Vexilar provides a balanced performance level for a wide range of
fishing scenarios.

Mounting the Flasher Unit
Transducer Types and Mounting Methods
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 traffic. The mounting surface should be
fairly flat. Be sure to allow clearance for the cables at the rear of the unit while it tilts and
swivels. 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.
There are several different transducer styles used for the various mounting options available
to you. Choose the style which best meets the needs for your mounting application.
To
install the fl asher unit :
1. Obtain four appropriate fasteners for your mounting location.
2. Remove the flasher 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

5. Attach the gimbal bracket using your
four fasteners. Tighten securely.
6. Replace the flasher unit into the
Gimbal Knob
gimbal bracket and tighten the
gimbal knobs snuggly.
Gimbal Bracket
Power Connection
Flasher Unit Assembly
Your flasher 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 a boat’s electrical system.
• If possible, power your flasher 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 fl asher to power :
1. Be sure the power cord is not connected to the flasher.
2. Route the power cable from the flasher 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 flasher’s power jack.

T ransducer T ypes
• 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 clear water flow
when running at high boat 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 fiberglass boats.
• AlumaDucer™: This style is specially designed for in-hull mounting in aluminum
boats. The transducer overcomes the inherent signal loss when shooting through
an aluminum hull. The Alumaducer™ is a Vexilar exclusive.

M ounting M ethods
• Transom Mounted: the method by which the transducer is mounted external 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 6)
• 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.
The use of an AlumaDucer™ is required to achieve a full strength signal when
mounting in aluminum hulls. (see page 8 & 9)
• Trolling Motor Mounting: the method by which the transducer is attached to the
lower unit of the electric trolling motor. (see page 10)
• 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 11)
DID YOU KNOW?: If you find that you have bought the wrong transducer for your
intended mounting application, you can exchange it with Vexilar. You will only need to
pay the retail cost difference, plus shipping, of the transducer style needed. Please call for

Transom Transducer Mounting
In-Hull Transducer Mounting
Before you begin the process of installing the transducer, check your hull to find a spot
where you’ll get a smooth water flow along the bottom of the boat. You want to avoid ribs,
rivets, and gouges or scratches in the hull.
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 (see page 8) and prepare the surface area. Also, the hull temperature should be
at least 60° F while performing the installation.
Less than 10°
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 flat with a
dead rise of 10° or less, mount the transducer
along the hull bottom. If dead rise is greater
than 10°, mount with the transducer aligned
level.

1. Assemble the stainless steel brackets to the transducer
using the hardware furnished. Do not tighten until final
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 transducer 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 final tightening the 4 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.
1/4” to 5/8”

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 fiberglass between the transducer and the
water.

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.

rough areas down to the base material for a
secure installation. Use the pad to rough-up
the face of your transducer a little too. 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 off 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 firmly and twist
slightly back-and-forth to work-out any air bubbles that might have been trapped in
the epoxy.
You’re done. However, do not power-up your depth sounder for at least 12 hours. Doing
so will effect epoxy curing.
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.

AlumaDucer™ Transducer Installation
Installation Procedures
IMPORTANT PRE-INSTALLATION INSTRUCTIONS
I nstalling
The AlumaDucer mounted in-hull helps many boaters get better performance and
protection from damage than ever before using externally mounted transducers. The key
to good performance is to understand the dynamics of how water flows under your hull at
different boat speeds. Fiberglass boats often have a flat spot or “pad” on the very rear of
the boat. This flat area is ideal for transducers to get a good clear reading at high speeds.
With aluminum hulls, this area may not be as obvious. Welded, flat bottom Jon boats are
often easy to find an area where smooth water without bubbles are flowing down the hull
of the boat. Boats with rivets, scratches, and/or dents along their bottom side create more
turbulence, so finding an area of smooth water without air pockets can be a challenge,
but it is possible in most cases. We highly recommend you test your boat to find the
optimal mounting location BEFORE installing the AlumaDucer. Here’s how to do it:
Select an area within one foot of the center keel of the boat and directly in front of the
bottom corner of the transom. This area is often near the drain plug. Your goal is to select
an area that is between ridges or rivets preferably in the center or towards the driver’s side
of the boat. You need to select an area of the hull that does not have a dent or depression
that might create a pocket of air while the boat is running at higher speeds. A simple
straight edge ruler can be used on the bottom of your hull to ensure you have selected a
non-warped area.
M ounting L ocation T esting
1. Head to your favorite testing waters and launch your boat.
2. Fill the rear bilge area of your boat with about an inch of water.
3. Remove the protective film from the transducer face and place the transducer in the
water in the desired position.
4. Connect the AlumaDucer to your depth finder. You don’t need to do any fancy
routing of the cable for now.
5. Go for a boat ride. Make sure you get good strong readings at all boat speeds. If
not, move the transducer around until you do.
If you don’t have a friend to help drive the boat while you’re moving the transducer around,
use a zip lock bag with beach sand in it, or something similar, to keep the transducer face
firmly in place on the hull and under the thin layer of water you have in your boat.
Once the “sweet spot” has been found, you simply drain your boat, dry the area thoroughly
and install the AlumaDucer by following the instructions on the next page.

the
A luma D ucer
1. Using the supplied Scotch-Brite® pad, remove any paint, dirt or coatings on the
aluminum. You MUST be down to the bare aluminum and the surface must be dry.
Wipe off all loose dust and dirt.
2. Using the supplied alcohol swab, wipe clean any dust or dirt you created from the
target area on the hull and the face of the transducer. Dry the area with a clean
paper towel or rag.
3. Set the transducer in the prepared area and place
four supplied foam positioning pads around the
transducer as shown. This will keep the transducer
from moving once the transducer has been
positioned.
4. Using the pre-measured packet, mix both elements of
the A.C.E. adhesive together, following the directions
on the packet. Once thoroughly mixed, you have
about 10 minutes to apply this special
A.C.E. Adhesive. (Accoustically Conductive Epoxy)
5. Remove transducer from the target spot. Apply the mixture to the transducer NOT
the boat. Be sure to use all the Epoxy in the packet.
6. Now, simply press the transducer back into the prepared area. Twist it slightly
back and forth several times. This is done to make sure no air pockets remain
under the transducer.
The special A.C.E. Adhesive will set
in about 30 minutes. Try not to move
the boat around during this period.
The foam cubes you placed around
the transducer keep it from drifting
from the spot you have selected while
the adhesive cures overnight. Do not
turn your sonar “on” for 12 hours to
ensure a solid connection between the
transducer and the aluminum hull.
IMPORTANT: The hull temperature should be at least 60° F for proper curing of the A.C.E.
adhesive.

Electric Trolling Motor Mounting
Portable Options
There are two main styles of trolling motors: manual steer and electric steer. The proper
mounting method depends on the style of trolling motor.
A suction cup bracket is an option if you want to quickly install and remove the transducer

rope to the bracket and then to the boat
leaving as little amount of slack as you
can. If the cup(s) come lose, this will
keep your transducer and cable out of

Did You Know?: Vexilar does not offer a suction cup bracket to fit the ice fishing style
transducers. This is because the Ice-Ducer cable is made to stay soft in very cold
temperatures. Therefore, it is very easy to damage in warm temperatures, thus open water
use is not recommended.

About the Display
Basic Use
The FL series flasher displays consist of three 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.
The Vexilar FL series color flashers are great tools for open water and ice fishing. Once you
learn to understand the color display, you can apply this knowledge to greatly increase
your awareness of what’s under the water.

Determining the current depth at any boat speed.
Locating fish-holding underwater structure.
Determining the bottom hardness and transition lines.
Penetrating thick vegetation to see what’s below.
Finding fish and the fish they feed on.
Watching your bait and the fish around it.
Operation of each of the flasher models is very straight forward. You simply turn the unit
on, select an appropriate depth range setting, and then an appropriate gain level setting.
You change the range and gain settings only when the conditions change.
RANGE
Range determines the maximum depth of water in which the flasher can see the bottom.
For example, the shallowest range available on all models 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’ll want to select a deeper depth
range.
DID YOU KNOW ?: 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 offers the highest resolution, makes things bigger and easier
to see.
GAIN
Gain controls the amount of amplification 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 find a gain level that
shows you as much real information as possible, without displaying stray signals of clutter
and interference.
INTERFERENCE REJECTION
This feature rejects sonar interference generated by other nearby depth sounders.
Interference Rejection, or IR, comes on automatically when you turn the flasher on, but
you can adjust the setting if desired.
12
RED = Strong Strength Signals. Strong signals are generally produced by
significant underwater objects, such as the bottom, heavy vegetation, and large fish.
However, smaller objects, such as bait fish, can display as red if the object is directly
under the transducers.
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 fish, and even air bubbles or aquatic micro marine
life. Larger objects off to the sides of the transducer can also be displayed as green.
What is What ?
Here are the basics of what you will see on
the display of an FL series flasher.
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 air bubbles from
choppy waters.
Marks beyond the bottom
mark can indicate either
hard objects within a soft
bottom or large objects
well off to the side.
Bottom is generally the
most prominent mark on
the display. Bottom usually
starts with a wide band
of red, with orange and
green trailing.
You read the
display in the clockwise direction. The
further around you
go the deeper the
water.
READ DEPTH HERE: The current depth
is indicated by the leading edge of the
bottom mark. The depth is 12 feet here.
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.

FL-8SE
The FL-8SE has six depth ranges in two groups, Shallow and Deep. The Shallow group
includes Zero to 20’, 40’, and 80’. The deep group includes Zero to 30’, 60’, and 120’.
To interpret depth, you multiply the displayed reading by the range multiplier.
FL-18
The FL-18 has 5 depth ranges. Zero to 20’, 40’, 60’, 80’, and 200’. To interpret depth,
you multiply the displayed reading by the range multiplier.

feet, a fish is at 12 feet, and there is a weak signal at 10 feet.
If the range control was set to “x2”, the bottom would be
interpreted as 30 feet, the fish at 24 feet, and the green mark
at 20 feet.

Setting the Gain
FL-12 and FL-20
Both the FL-12 and FL-20 have five depth ranges consisting of Zero to 20’, 40’, 60’, 80’,
and 200’. To read depth, you match the color of the range selected with the depth scale
of the same color.
Gain functions in the way same on all models. However, the FL-8se and FL-18 have a
different scale than the FL-12 and FL-20.
G ain S cale
• The FL-8se and FL-18 use a zero to ten scale.
• The FL-12 and FL-20 use a Minimum to Maximum scale.
FL-8se / FL-18 Gain Control
Match the color in which the range knob is pointing to the same colored
depth scale. Here, the range is set to 20 feet, which is yellow. To read
depth, look at the yellow scale on the flasher display.
If you change to the 40 foot range, you’ll look at the red depth scale, which
is just inside the yellow 20 foot scale.
For the 200 foot range, look at the outer 20 foot scale, but add a zero to
the reading, i.e. 10 feet would be read as 100 feet.
The 20’ Low Power range reads the same as the standard 20 foot range, except that using
this selection puts the flasher into Low Power Mode, which is discussed on page 20.
16
FL-12 / FL-20 Gain Control
Gain controls the amount of amplification 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 find a gain level that
shows you as much real information as possible, without displaying stray signals of clutter
and interference.
Start at a low gain setting, near minimum. Turn up the gain, if necessary, until you see what
you want to see. Generally, gain levels between minimum and one third are adequate for
most situations. Higher gain levels should only be required to read in deeper water or to
see small objects.
DID YOU KNOW ? Gain can act as a variable cone angle. As you increase the gain level,
you can see things further away from the transducer. This can be helpful in uncluttered
conditions. If you don’t see anything on the screen (other than bottom), turn up the gain
temporarily and see if anything shows up. If it does, it could be a fish some distance away
from your transducer. Unfortunately, this won’t work in cluttered water, such as weedy
conditions, because the objects in the center of the cone will get amplified and overlap
anything on the outside, making these objects impossible to distinguish.
17
Interference Rejection
FL-8SE
and
FL-12
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 flasher. It is also helpful when other fishermen
are running sounders operating at the same frequency as your flasher nearby.
Interference Rejection comes on automatically when
you power up the flasher. You can turn it off by
pressing on the gain control.
Cross-talk interference occurs when the signals sent from one depth sounder are received
by another. If the two sounder’s frequencies are the same, each unit is unable to differentiate
between it’s own signals and others. What you see as interference is actually the reading
of the other sounder displayed on your screen. The signals can circle around the display
or remain stable. Beware of the stable signals. They can lead you to believe the depth is
different than it is or that there’s a fish hanging below you which really isn’t 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 flasher next to another sounder which does not have the I.R. 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
control set at one level on one unit, while adjusting out the interference displayed on both
units using the second unit’s IR feature.
If interference from another sounder is present on
the display, press this button repeatedly until it goes
away or is reduced as much as possible.
FL-18
and
FL-20
Interference Rejection comes on automatically when you power up
the flasher. If interference from another sounder is present on the
display, press the gain control repeatedly until it goes away or is
reduced as much as possible.
Interference occurs when the cone angles of two different 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.

Low Power Mode ( FL-12, FL-18, FL-20 Only )
Low Power Mode, or LP Mode, reduces the output power of your flasher. It is useful for
situations where the gain cannot be turned down enough in Normal Mode. Use the Low
Power Mode only when you need to. Usually, you’ll use it in only very shallow or very
weedy conditions.
Auto Zoom ( FL-18 and FL-20 Only )
Auto Zoom (AZ) puts the flasher into a split-screen view, with the complete water column on
the right and a magnified view from the bottom on the left. When you switch to Auto Zoom
Mode, the flasher automatically selects the magnified bottom view for you. However, you
do need to have the flasher set to a depth range in which the bottom is in view.
FL-18
Activate the Low Power Mode (LP) by switching the Mode control to the
left. The range can be set at any position. If you switch to the left of LP,
you can activate the AZ or BL Modes in Low Power Mode.
FL-12 and FL-20
Activate the Low Power Mode by switching the range control
from OFF to the left. The range will be set to 20 feet. You can
use any of the Mode settings in Low Power Mode.
DID YOU KNOW ? Low Power Mode has little to do with how much battery power is
required to run the flasher. Switching to Low Power Mode will not significantly increase
your running time on a battery.
DID YOU KNOW ? You can have a Low Power Mode feature on an FL-8se too by
purchasing a Vexilar S-Cable. Learn more about it on page 43.
20
FL-18
Activate Auto Zoom by switching the
Mode control to the AZ selection on
the right or the left. The right selection
operates Auto Zoom at the normal
power level. The left selection operates
Auto Zoom in Low Power Mode.
See page 22.
FL-20
Activate the Auto Zoom by switching the
Mode control to either the AZ 6’ or AZ
12’ setting to the right, or the AZ 6’ or AZ
12’ setting to the left. The right (Yellow)
settings operate with the display at full
brightness. The left (Red) settings operate
the display in Night Mode, discussed on
page 24.
Bottom Lock (BL)
The FL-18 also has a zoom feature called
Bottom Lock (BL). This feature is discussed
more on page 24
FL-20 Low Battery Indicator
When battery power runs low, the red “Low Battery”
indicator light will turn on. You can continue to use the
flasher, but be aware your time is rapidly decreasing.
When the indicator light begins to flash, failure due to
low voltage is imminent.
21
Understanding Auto Zoom
When Auto Zoom (AZ) is active, the display is divided into two halves. When reading
depths always use the inner scale on the right side. When the range is set to 20, read
this scale “as is”. When the range is set to 40, double the reading. If set to 60, triple the
reading.
FL-18 - Auto Zoom
THE LEFT HALF represents the zoom
view. From the bottom up six feet.
Read the distance from the
bottom using the inner

THE LEFT HALF represents the zoom

inner red/white scale.
THE RIGHT HALF represents the entire
water column, from the water surface

Bottom
The Zoom scale reads in the
opposite direction as the full view
scale. The bottom will always be at
the 7 O’clock position. Objects will appear
above this point. You can only see objects as far
off the bottom as the zoom setting permits, which is 6
feet. Objects above this level will only appear on the right side
which show the entire water column.

feet. Objects above this level will only appear on the right side
which show the entire water column.
Fish
20’ Range = 1x
40’ Range = 2x
60’ Range = 3x
80’ Range = 4x
200’ Range = 10x
IMPORTANT Zoom should be activated only when the transducer is submerged. If the
zoom is activated before the transducer is placed in the water, such as when moving from
ice fishing hole to hole while the zoom is operating, the bottom may not line up with the
zero mark on the zoom scale correctly. If this happens, simply switch the flasher to Normal
Mode, or Full View Mode, and then back to Zoom to reset the feature.
IMPORTANT If the depth of water changes while a zoom mode is selected, the bottom
position on the zoom scale will change accordingly. If the bottom signal moves off of
the display, reset the zoom by switching back to the Normal Mode momentarily. For this
reason, the Zoom Mode is not recommended for use on boats where changes in depth
are commonly occurring.
23
Bottom Lock ( FL-18 Only )
The FL-18 also has a zoom feature called Bottom Lock (BL). This works the same as Auto
Zoom, except the flasher continuously updates the position of the bottom in the magnified
view. This can be helpful in a boat that is moving over varying depths or is riding in heavy
waves.
To activate Bottom Lock, switch the Mode Control to the far right for normal power
operation, or the far left for Low Power Mode operation.
Bottom Lock will keep the bottom reading lined up correctly with the zero mark on the
Zoom scale. This allows you to see objects which are very close to the bottom, even
though the depth may be changing rapidly. The range control must be set to a position
where the bottom is displayed in order for Bottom Lock to function.
IMPORTANT - Bottom Lock works best for boats in motion. When still fishing, such as
vertical jigging or ice fishing, the Bottom Lock feature can incorrectly identify a large
object slowly moving into your view as a shallower depth change. The result is that the
flasher adjusts to the new level and the object is displayed as the bottom.
Bottom Lock is not available on the FL-20
Bo at Use
Navigation
The Vexilar FL series flashers are great tools for navigation while boating. The instantaneous
readings offer the ability to identify depth changes quickly. Here are some tips to help you
navigate safely.
CAUTION:
• Be sure you know which range you have selected. If you think you have the flasher
set to a deeper range than what it actually is, you may run aground unexpectedly.
• Be aware that although the depth displayed may be deep enough to navigate in
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 extremely shallow. It may, in fact, be
deeper than the selected range, but never assume so without checking first.
• Use common sense. Do not trust the flasher as the ultimate source of information.
Use good judgement as well.
Night Mode ( FL-20 Only )
Bottom Content
Night Mode reduces the flasher’s display brightness to make night time viewing more
comfortable to your eyes. The display intensity is reduced by about 50%. To activate
Night Mode, switch the Mode control to either the Full View, AZ 6”, or AZ 12’ position
to the left.
The Vexilar FL series flashers 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.
H ard or S oft B ottom
• Hard bottoms will generally appear as a narrow band with color content of mostly red
and orange.
• Soft bottoms will appear a wide band with more orange and green than red.

Vegetation
Ice F i s hing
The Vexilar FL series flashers are exceptional when it comes to reading inside vegetation.
With proper adjustment, the colors will allow you to differentiate vegetation from the
bottom. Experience will even allow you to identify fish inside heavy vegetation.
Basic Principles
T ips for R eading in V egetation
• Narrow transducer cone angles will perform better than wide cone angles.
• Keep the gain setting very low. Too much gain will make readings difficult.
• Move a boat slowly so you can identify openings that may hold fish.
Bottom
Bottom will always be
the largest group of red
and orange signals.
Possible Fish
Orange within the green
generally indicates
thicker sections of the
vegetation. Although it
warrants watching, as
it could also indicate a
fish on the outer edge of
your cone.
26
Although this red target
could indicate a clump
of vegetation, it could
also indicate a fish just
under the canopy
The FL series color flashers offer distinct advantages over traditional depth sounders for
the sport of ice fishing. This unique style of fishing offers a stable platform to fish from.
Because everything is so stable, the only movements below are that of fish. Additionally,
the conditions allow you to drop your bait directly down into the center of the transducer’s
cone of sound. This allows you to be able to see your bait and the fish on the display at
the same time. You can tease the fish and see his reaction.
Vegetation grows 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
WARNING - Before venturing onto the ice to go fishing, be sure you know if the conditions
are safe. Check with the local bait shops AND check the ice thickness yourself. You should
have at least 6” of clear ice to safely support yourself and your ice fishing equipment.
27
Ice Fishing Transducer
Seeing Your Lure
Vexilar ice fishing systems include a special type of patented transducer, called an IceDucer. This transducer style is designed specifically for the ice fishing application. The IceDucer works off the “plumb-bob” theory. When suspended by the cable, the transducer
cone is perfectly aligned to point straight down.
The key to ice fishing success when using a Vexilar ice fishing system is in the ability to see
your fishing lure and it’s relationship to the bottom, structure, and fish. Ice fishing with a
Vexilar allows you to present your lure to the fish. You see the fish on the display and you
raise or lower your lure so it is right in front of it. If the fish 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 flasher display and adjust your tactics accordingly.
I ce -D ucer C omponents
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.
T ypical I ce F ishing V iew
This illustrates a typical pan
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.
Float - The float suspends the transducer in the ice hole. You
can also use the eye-bolt included with the Vexilar ice fishing
systems to suspend the transducer. This can often be the best
choice for early ice conditions.
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.
Cable - Ice-Ducer cable is specifically designed to stay flexible
in cold temperatures. This flexible 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 fishing
environment. Several models with different cone angles are
available.
28
Bottom
Fish
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.
A pair of fish are rising to your lure
as it is being dropped down. This is a
good sign, as competition can make
the fish more aggressive.
DID YOU KNOW ? 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 weak signal. Because the fish 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 effect the strength of your lure’s signal.

D-130
The D-130 will continue to
measure capacity and trend as long as it is
connected to the battery. When an additional
“load” is applied to the battery, the capacity
will decrease according to the load applied.
T-130
ON LED
Power is connected. If no other LEDs are illuminated,
the voltage is very low.
IMPORTANT: The T-130 will not show an accurate
level when the charger is connected. Remember to
use the charger's LED as your "Charge Complete"
indicator. Also, the percent of charge shown will
vary with the temperature and battery load.
Readings will be most accurate when the flasher is
running and the temperature is above 50° F.
When the load is removed the digital readout
will remain at the last shown level and the trend
arrow will switch to ( ). This rebound indicates
the battery is starting to recover, but the digital
readout of the capacity will hold at its lowest
level unless you reset the unit by disconnecting and reconnecting the D-130 to the battery.
*If you continue to use the D-130 without disconnecting it, the D-130 will show the last capacity until the battery
falls below this point, then continue to decline with use.
When a charger is attached to the system, the digital readout of capacity will remain the same, up
to an hour, with an ( ) arrow indicating that it is receiving a charge, before the digital readout will
start to advance. Note, with some batteries, the very top rating for a charged battery (12.7 volts)
or 100% rating will not stay at 100% even though it might be fully charged. This is normal.
Each battery charges differently and may be fully charged but show 95%, instead of 100%. This
is a normal occurrence with batteries since not all batteries will hold the same top-end percentage
when fully charged and is not an indication of a poor or defective battery.
When you reconnect the D-130 to the battery, the display will show the current status of the battery
at that moment.
IMPORTANT: Be sure the indicators are not on during long storage periods, as excessive
battery drain can result. For Pro Pack systems, disconnect the indicator from the battery
before storage. For Ultra Pack systems, be sure the master power switch is off.

CHARGE AFTER EACH USE
1 Allow the battery to warm up before charging.
2 Connect the red charger clip to the positive battery terminal
(+ RED) and the black clip to the negative terminal (- BLACK).
3 Plug the wall transformer into a standard 110 volt socket.
Charge the battery until the red LED goes off and the green
LED comes on.
Charging times will vary depending on how much the battery has
been drained. If the battery has been completely drained (approx.
24 hrs. of use on a 9 amp battery) the battery will require about
9 hours of charging. Once the battery is fully charged and the
green LED comes on, the charger switches to a maintenance mode. You can leave the
charger connected to the battery indefinitely and the battery will be maintained at full
charge.
1/2 Amp Charger (model V-150 / 500 mA)
1. Allow the battery to warm up before charging.
2. Plug the wall transformer into a standard 110 volt socket. The
red LED will come on.
3. Connect the red charger clip to the positive battery terminal
(+ RED) and the black clip to the negative terminal (- BLACK).
The red LED will now go out.
4. Charge the battery until the red LED comes back on to full
brightness.
5. Remove the charger when the battery is full. Do not charge for
more than 72 hours after the red LED has come on.
Charging times will vary depending on how much the battery has been drained. If the
battery has been completely drained (approx. 18 hrs. of use on a 7 amp battery) the
battery will require approximately 48 hours of charging.
DID YOU KNOW? There is no need to disconnect the flasher when charging, although it
should be switched off. Also, make sure the battery has a full charge and is disconnected
or that all power is switched off before putting it away for storage. Remember to charge
after each use.
IMPORTANT: If you have an Ultra Pack system, be sure your Master Power switch is ON
and the flasher is turned OFF for charging,

Dead Zone
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. In actuality, the cone of sound is not so precisely defined.
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.
Transducer
Theoretical Cone Angle
The theoretical cone
angle is what the
transducer’s specification
defines. This is the area
where the intensity of the
sounds waves drop to a
specific point (-6dB).
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.

distance it sees. If you are fishing
over a slope, it may see the high side of the slope, at the edge
of the cone, and mark that as bottom. The fish 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 finder. A narrower beam angle will reduce this effect.
Output Power
Your depth finder 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 that
same amount of power into a smaller area. This can be an advantage if you are fishing in
deep water or a detriment if you are fishing in shallow water. A narrow beam transducer
can be overpowering in shallow water. The use of the LP (Low Power) mode on your
flasher, or the optional S-Cable (page 43), will solve this problem.
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 sufficiently reflect 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 fish or tight group of
smaller fish.

Electrical Interference
S ymptom
P ossible C ause
Unit is turned on, but no display and motor is
not running.
Check for bad connections, proper hook up
polarity, and make sure you have a good, fully
charged, battery.
Unit is turned on and the motor is running, but
there is no display.
Battery voltage too low. The unit will show no
display if the voltage is below 8 volts. Check
voltage while unit is running.
There may be situations where you experience interference from other electrical devices,
not just another nearby depth sounder. This interference will show on your display as
random signals which can appear anywhere. They will interfere with your ability to see
the normal display signals. The most common sources of interference are electric trolling
motors and engine ignitions systems. The Interference Rejection feature will not have
much effect on these types of interference, as this feature is designed to only deal with
signals from another sonar device. Here are some things to be aware of when it comes to
electrical interference.
Unit runs well for a short time, then lights fade
out or unit quits.
Bad battery or connection. Voltage may be
good when checked, but will fall as unit runs.
S ources
Unit runs and shows display light, but does not
read depth.
Transducer is not plugged in or not in contact
with the water.
Unit works, but needs high gain to see bottom
or targets.
Transducer is not aimed correctly or needs to
be cleaned. 19º transducers will have trouble
seeing small targets deep.
Unit works, but has too many lines on the
display. Can't tell what is what.
Improper transducer adjustment. Also, gain
may be set too high or ,if gain is set to
minimum, switch to the LP Mode.
Unit works well when sitting still or at when
slow trolling, but loses reading at higher
speeds.
Improper transducer type, installation, or
adjustment causing a loss of clear water flow
across the transducer when the boat reaches a
certain speed.
Unit shows noise when engine or electric
motor is turned on.
Defective engine or electric motor. Also can
be improper grounding or missing ground in
electrical system.
I.R. does not work. Can’t eliminate interference Gain may be set too high or the other unit
from other depth finder.
has a problem. Also, check for ice or debris
buildup under the gain control.
Maintenance
Clean the flasher body and screen with a soft cloth and a mild detergent. Do not submerge
in water or other liquids.
Do not expose the body or display to chemicals, such as fish attractant or insect repellent.
Damage to the surfaces can occur.
Interference can be introduced into your sonar system through the power supply, transducer
line, or both. To identify the source, unplug the transducer and run the trolling motor or
the engine. If the interference disappears, you know the noise is coming in through the
transducer line. If not, it’s coming through the power line, or both.
W iring
Power line interference can generally be solved by improvements in the wiring positions,
connections, and grounding. You want to be sure the sonar wiring is as far away as
possible from the trolling motor wiring, and the wiring is neat. Make cable runs as short
as possible and neatly coil extra wire and tie it off so it stays put in rough water or
while pulling the boat. All electrical connections should be in very good condition. Pushon terminals should be tight. Wire crimp connections should not come free when pulled
firmly. Conductors should be shiny, not dull or corroded.
G rounding
The boat’s electrical system should have a common “Earth” ground to the water. Most
boats electrical systems are grounded through the outboard to the water. Many times a
electric trolling motor interference problem can be solved by a “ground” wire from the
negative trolling motor power source to the negative of the starting battery.
E quipment
Electric trolling motors and main engines can have technical problem that cause
interference. If common wiring improvements do not solve the problem, be sure to check
with the manufacturer to see if there are any recommendations or updates available
regarding interference with depth sounders.
For more information regarding interference issues, check the Help Department of the
Vexilar web site or contact our service department.
