How Sonar Works
Sonar technology is based on sound waves. The Fishing System uses sonar
to locate and define structure, bottom contour and composition, as well as
depth directly below the transducer.
Your Fishing System sends a sound wave signal and determines distance by
measuring the time between the transmission of the sound wave and when
the sound wave is reflected off of an object; it then uses the reflected signal
to interpret location, size, and composition of an object.
Sonar is very fast. A sound wave can travel from the surface to a depth of
240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that
your boat can "outrun" this sonar signal.
SONAR is an acronym for SOund and
NAvigation Ranging. Sonar utilizes precision
sound pulses or "pings" which are emitted into
the water in a teardrop-shaped beam.
The sound pulses "echo" back from objects in
the water such as the bottom, fish and other
submerged objects. The returned echoes are
displayed on the LCD screen. Each time a new
echo is received, the old echoes are moved
across the LCD, creating a scrolling effect.
When all the echoes are viewed side by side,
an easy to interpret "graph" of the bottom, fish
and structure appears.
2
Introduction
The sound pulses are transmitted at various
frequencies depending on the application.
Very high frequencies (455 kHz) are used for
greatest definition, but the operating depth is
limited. High frequencies (200 kHz) are
commonly used on consumer sonar and
provide a good balance between depth
performance and resolution. Low frequencies
(83 kHz) are typically used to achieve greater
depth capability.
The power output is the amount of energy
generated by the sonar transmitter. It is
commonly measured using two methods:
• Root Mean Square (RMS) measures power
output over the entire transmit cycle.
• Peak to Peak measures power output at the
highest points.
The benefits of increased power output are
the ability to detect smaller targets at greater
distances, ability to overcome noise, better
high speed performance and enhanced depth
capability.
High Definition
Side Imaging®Sonar
(898c SI and 998c SI only)
The 898c SI Combo and 998c SI Combo
use Side Imaging® sonar to provide a
wide yet precise survey of a large area
of water, including detailed bottom
topography and fish-attracting structure
orientation. The Side Imaging®
transducer returns are processed into an
image similar to an aerial photograph.
Typically, the Side Imaging® sonar can
search an area that is 480 feet wide (240
to each side), with a typical depth
performance of 150 feet when the Side
Imaging® Sonar frequency is set for
455kHz. The side beams can be
operated at one of two frequencies:
455 kHz or 800 kHz. Selecting 800 kHz
produces the sharpest image, but the
search area to each side and the depth
capability are limited as compared to the
455 kHz frequency. See What’s on the
Side Imaging® Display and
Understanding Side Imaging® for more
information.

DualBeam PLUS™ Sonar
(858c, 898c SI, 958c, 998c SI)
The Fishing System uses a 200/83 kHz
DualBeam PLUS™ sonar system with a wide
(60°) area of coverage. DualBeam PLUS™
sonar has a narrowly focused 20° center
beam, surrounded by a second beam of 60°,
expanding your coverage to an area equal to
your depth. In 20 feet of water, the wider
beam covers an area 20 feet wide.
DualBeam PLUS™ sonar returns can be
blended together, viewed separately, or
compared side-by-side. DualBeam PLUS™ is
ideal for a wide range of conditions - from
shallow to very deep water in both fresh and
salt water. Depth capability is affected by
such factors as boat speed, wave action,
bottom hardness, water conditions, and
transducer installation.
QuadraBeam PLUS™ Sonar
(optional-purchase QuadraBeam PLUS™
transducer only)
Your Fishing System supports the
optional-purchase QuadraBeam PLUS™
transducer. QuadraBeam PLUS™ sonar
provides a wide (90°) area of coverage.
QuadraBeam PLUS™ starts with two
fan-shaped 35° 455 kHz Side Structure
locating sonar beams to spot fish, bait,
and structure to the left and right of the
boat over an area of the bottom that’s
always equal to twice your depth.
For a detailed view below the boat,
QuadraBeam PLUS™ uses DualBeam
PLUS™ technology, with precision 20°
and wide 60° beams. QuadraBeam
PLUS™ finds more fish faster, and can
even tell you where to put your bait by
showing if fish are to the left, right, or
directly beneath your boat.

How GPS and Cartography Work
Your Fishing System also supports GPS (Global Positioning System) and
chartplotting. It uses GPS and sonar to determine your position, display it on
a grid, and provide detailed underwater information.
GPS uses a constellation of satellites that
continually send radio signals to the earth. The
GPS receiver on your boat receives signals from
satellites that are visible to it. Based on time
differences between each received signal, the
GPS receiver determines its distance to each
satellite. With distances known, the GPS
receiver mathematically triangulates its own
position. With once per second updates, the
GPS receiver then calculates its velocity and
bearing.
GPS was originally intended for military use; however, civilians may also take
advantage of its highly accurate position capabilities, typically within +/- 4
meters, depending on conditions. This means that 95% of the time, the GP
receiver will read a location within 4.5 meters of your actual position. Yo
GPS Receiver also uses information from WAAS (the Wide Are
Augmentation System), EGNOS (the European Geostationary Navigat
Overlay Service), and MSAS (the MTSAT Satellite Augmentation Syst
satellites if they are available in your area.
The following GPS functionality is currently supported by the Fishing Syst
when it is connected to the included GPS receiver:
• View current position
• View current track (breadcrumb trail)
• View precision speed and heading from your GPS receiver
• Save tracks, waypoints, and routes
• Travel a route and navigate from one waypoint to the next.

Installation Overview
Inside the boat there is often a channel or conduit used for other wiring, this
can be used to route cables. Be sure to route the cable as far as practical
from the antenna cable of VHF radios or tachometer cables to reduce the
possibility of interference. The transducer and GPS receiver cables shou
not be cut, and care should be used not to damage the cable insulation.
Basic installation tasks that you must perform include:
• (choose gimbal or in-dash mounting,Installing the control head
where in-dash mounting requires a separate purchase)
• (choose the installation method thatInstalling the transducer
matches your transducer)
• (if included)Installing the GPS Receiver
• Testing the complete installation and locking the transducer position
NOTE: Accessories may require a separate purchase. You can visit our web site
at humminbird.com to order these accessories online or contact our Customer
Resource Center at 1-800-633-1468.
Control Head Installation
You have two choices for mounting your control head, Gimbal mounting
where you use a surface on the boat, such as the dash, to mount the control
head so that it can be tilted up or down, or , which requiresIn-dash mounting

alternate hole patterns.
4. Place the gimbal bracket in the chosen position on the mounting
surface and mark the four mounting screw locations using a pencil
or center punch.
NOTE: Go to the installation instructions applicable to your transducer, GPS
Receiver and accessories. Make the required installations and then run the
cables to your control head mounting location. Do not cut any cabling (except the
power cable). If your cables are too short, extensions are available from your local
dealer or online from humminbird.com.
5. Set the gimbal bracket aside and drill the four mounting screw holes
using a 5/32" (4.0 mm) drill bit.
6a. If the cables must pass through a hole directly beneath the
mounting bracket, mark and drill an additional 1" (25 mm) hole
centered between the four mounting holes. Route the cables
through the 1" hole. Place the hole cover over the mounting surface
hole, then use it to mark the position of the two mounting screws.

back of the control head, lock the assembly into place by threading
the knurled screw into the threaded insert on the back of the
housing. Adjust the control head to the desired viewing angle and
secure by tightening the gimbal knobs.
NOTE: You may wish to dress the cabling with nylon wire ties in order to hold the
cables together and create a cleaner assembly.
The Humminbird® control head is now ready for operation.
Connecting the Control Head Power Cable to the Boat
A 6' (2 m) long power cable is included to supply power to the control head
You may shorten or lengthen the cable using 18 gauge multi-stranded
copper wire.
CAUTION: Some boats have 24 or 36 Volt electric systems, but the control head
MUST be connected to a 12 VDC power supply.
The control head power cable can be connected to the electrical system of
the boat at one of two places: a fuse panel usually located near the console,
or directly to the battery.
NOTE: Make sure that the power cable is disconnected from the control head at
the beginning of this procedure.
NOTE: Humminbird® is not responsible for over-voltage or over-current failur

858c & 958c Transom Mount Transducer Installation
DualBeam PLUS™ Transducer, XNT 9 20 T (858c and 958c only)
The DualBeam PLUS™ transducer uses a Two Piece Kick-up transducer
mounting bracket.
NOTE: Due to the wide variety of hulls, only general instructions are presented in
this installation guide. Each boat hull represents a unique set of requirements that
should be evaluated prior to installation. It is important to read the instructions
completely and understand the mounting guidelines before beginning
installation.
NOTE: Your transducer may not look exactly like the transducer shown in the
illustrations, but it will mount in exactly the same way.
Overview
If you will be installing a DualBeam PLUS™ transom mounted transducer, u
the procedures in this section. There are several procedures you will have to
perform in order to install a transom-mounted transducer. They are as
follows:
• Locate the transducer mounting location
• Prepare the mounting location
• Assemble the transducer and perform initial mounting
• Route the transducer cable
• Connect the transducer cable
• Perform a final test of the transom transducer installation.
In addition to the hardware supplied with your transducer, you will need a
powered hand drill and various drill bits, various hand tools, including a rul
or straightedge, a level, a 12" plumb line (weighted string or monofilamen
line), marker or pencil, safety glasses and dust mask, and marine-grade
silicone sealant.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bi
and use progressively larger drill bits to reduce the chance of chipping or flaking
the outer coating.
14
Transom Mount - DualBeam PLUS™
1. Locating the transducer mounting location
NOTE: If transom mounting is not possible because of a stepped hull or
cavitation noise, and you have a single layer fiberglass hull, In-hull installation is
an option. See Inside the Hull Transducer Installation for more information.
Turbulence: You must first determine the best location on the transom to
install the transducer. It is very important to locate the transducer in an area
that is relatively free of turbulent water. Consider the following to find the
best location with the least amount of turbulence:
• As the boat moves through the water, turbulence is generated by the
weight of the boat and the thrust of the propeller(s) - either clockwise
or counter-clockwise. This turbulent water is normally confined to areas
immediately aft of ribs, strakes or rows of rivets on the bottom of the
boat, and in the immediate area of the propeller(s). Clockwise
propellers create more turbulence on the port side. On outboard or
inboard/outboard boats, it is best to locate the transducer at least 15"
to the side of the propeller(s).
• The best way to locate turbulence-free water is to view the transom
while the boat is moving. This method is recommended if maximum
high-speed operation is a high priority. If this is not possible, select a
location on the transom where the hull forward of this location is
smooth, flat and free of protrusions or ribs.
• On boats with stepped hulls, it may be possible to mount the
transducer on the step. Do not mount the transducer on the transom
behind a step to avoid popping the transducer out of the water at
higher speeds; the transducer must remain in the water for the
control head to maintain the sonar signal.

• If the transom is behind the propeller(s), it may be impossible to find
an area clear from turbulence, and a different mounting technique or
transducer type should be considered, such as an Inside the Hull
Transducer (see Inside the Hull Transducer Installation).
• If you plan to trailer your boat, do not mount the transducer too close
to trailer bunks or rollers to avoid moving or damaging the transducer
during loading and unloading of the boat.
• If high speed operation is critical, you may want to consider using an
In-Hull transducer instead of this Transom Mount transducer.
NOTE: The hydrodynamic shape of your transducer allows it to point straight down
without deadrise adjustment.
NOTE: If you cannot find a transom mount location that will work for your high-
speed application, find an In-Hull Transducer by contacting our Customer Resource
Center at either 1-800-633-1468 or by visiting our web site at humminbird.com.
2. Preparing the Mounting Location
In this procedure, you will determine the mounting location and drill two
mounting holes, using the transducer mounting bracket as a guide.
1. Make sure that the boat is level on the trailer, both from port to
starboard and from bow to stern, by placing your level on the deck of
the boat, first in one direction, then in the other.
2. Hold the mounting bracket against the transom of the boat in the
location you have selected. Align the bracket horizontally, using the
level; make sure that the lower corner of the bracket does not
protrude past the bottom of the hull, and there is at least 1/4"
clearance between the bottom of the bracket and the bottom of the
transom for fiberglass boats, and 1/8" clearance for aluminum
boats.
NOTE: If you have a flat-bottomed aluminum boat, some additional adjustment
may be needed to accommodate the rivets on the bottom of the boat (i.e. the gap
may need to be a little smaller than 1/8"). This will help you to avoid excessive
turbulence at high speeds.
NOTE: If your propeller moves clockwise (in forward, as you're facing the stern o
the boat from behind), mount the transducer on the starboard side, and align the
bottom right corner of the mounting bracket with the bottom of the boat. If your
propeller moves counter-clockwise (in forward, as you're facing the stern of the
boat from behind), mount the transducer on the port side, and align the bottom
left corner of the mounting bracket with the bottom of the boat.

3. Continue to hold the bracket on the transom of the boat, and use a
pencil or marker to mark where to drill the two mounting holes.
Mark the drill holes near the top of each slot, making sure that your
mark is centered in the slot.
4. Make sure that the drill bit is perpendicular to the actual surface of
the transom, NOT parallel to the ground, before you drill. Using a
5/32” bit, drill the two holes only to a depth of approximately 1”.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce
the chance of chipping or flaking the outer coating.
3. Assembling the Transducer and Initial Mounting
In this procedure, you will assemble the transducer using the hardware
provided, then mount it and make adjustments to its position without lockin
it in place.
NOTE: You will initially assemble the transducer and the pivot arm by matchin
the two ratchets to a numbered position on the transducer knuckle. Further
adjustments may be necessary.
1a. If you already know your transom angle, refer to the chart below for
the initial position to use to set the ratchets. If your transom is
angled at 14 degrees (a common transom angle for many boats) use
position 1 for the ratchets. In either case, go to step 2.
or...
1b. If you do not know your transom angle, measure it using a plumb
line (weighted nylon string or monofilament line) exactly 12 inches
long. Hold the top of the plumb line against the top of the transom
with your finger, and wait until the line hangs straight down. Using
a ruler, measure the distance from the bottom of the plumb line to
the back of the transom, then use the chart.

NOTE: It is important to take your measurement in
the figure showing Measuring the Transom
Angle, from exactly 12 inches down from the top
of the transom.
2. Place the two ratchets, one on either
side of the transducer knuckle, so that
the beads on each ratchet line up with
the desired position number on the
knuckle. If you are setting the ratchets
at position 1, the beads on each ratchet
will line up with the rib on the
transducer knuckle to form one
continuous line on the assembly.
NOTE: The ratchets are keyed; make sure that
the square teeth on each ratchet face the
square teeth on the transducer knuckle, and
the triangular teeth face outward.
Hold the ratchets on the transducer knuckle with one hand and fit
the pivot arm over them until it snaps into place with the other
hand. Refer to the illustration.

7. Adjust the transducer assembly vertically, until the seam on the
leading edge of the transducer (the edge closest to the transom of
the boat) is level and just slightly below the hull.
NOTE: The transducer has a natural downward slant of 4-5 degrees from leading
edge (closest to the boat transom) to trailing edge (farthest away from the boat).
Looking at the back of the transducer, the seam should be slightly below the
bottom of the hull.
8. Continue to adjust until the bracket is also level from port to
starboard (horizontally level as you look at the transducer from
behind the boat).
9. Mark the correct position on the transom by tracing the silhouette
of the transducer mounting bracket with a pencil or marker.
10. Tighten the pivot bolt, using the pivot screw and nut to lock the
assembly. Hand tighten only!
11. Snap open the assembly and hand-tighten the two mounting
screws, then snap the assembly closed.

4. Routing the Cable
The transducer cable has a low profile connector, which must be routed to
the point where the control head is mounted. There are several ways to route
the transducer cable to the area where the control head is installed. The
most common procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can
use for the transducer cable.
1. Unplug the other end of the transducer cable from the control head.
Make sure that the cable is long enough to accommodate the
planned route by running the cable over the transom.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the
cable insulation. Route the cable as far as possible from any VHF radio antenna
cables or tachometer cables to reduce the possibility of interference. If the cable
is too short, extension cables are available to extend the transducer cable up to
a total of 50'. For assistance, contact the Customer Resource Center at
humminbird.com 1-800-633-1468or call for more information.
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough
slack in the cable for this movement. It is best to route the cable to the side of
the transducer so the transducer will not damage the cable during movement.
2a. If you are routing the cable over the transom of the boat, secure the
cable by attaching the cable clamp to the transom, drilling 9/64"
diameter holes for #8 x 5/8" wood screws, then skip directly to
procedure 5, Connecting the Cable.
or...
2b. If you will be routing the cable
through a hole in the transom, drill a
5/8" diameter hole above the
waterline. Route the cable through
this hole, then fill the hole with
marine-grade silicone sealant and
proceed to the next step
immediately.
3. Place the escutcheon plate over the
cable hole and use it as a guide to
mark the two escutcheon plate
mounting holes. Remove the plate,
drill two 9/64" diameter x 5/8" deep
holes, and then fill both holes with
marine-grade silicone sealant. Place
the escutcheon plate over the cable
hole and attach with two #8 x 5/8"
wood screws.
4. Route and secure the cable by attaching the cable clamp to the
transom; drill one 9/64" diameter x 5/8" deep hole, then fill the hole
with marine-grade silicone sealant, then attach the cable clamp
using a #8 x 5/8" screw.
5. Plug the other end of the transducer cable back into the control
head connection holder.
Routing the Cable
21 Transom Mount - DualBeam PLUS™
NOTE: If there is excess cable that needs to
be gathered at one location (as shown in
the illustration), dress the cable routed from
both directions so that a single loop is left
extending from the storage location.
Doubling the cable up from this point, form
the cable into a coil. Storing excess cable
using this method can reduce electronic
interference.
5. Connecting the Cable
Insert the transducer cable into the appropriate terminal slot. The cable
connectors are labeled, and there are corresponding labels on the cable
holder on the rear of the control head. The slots are keyed to prevent
reversed installation, so be careful not to force the connector into the holder.
Refer to your manual and/or control head installation guide for the correct
procedure for installing the cable connectors to the control head.
1. Plug the other end of the transducer cable back into the control
head connection holder.
Your control head is now ready for operation.
6. Test and Finish the Installation
Once you have installed both the control head and the transom transducer,
and have routed all the cables, you must perform a final test before locking
the transducer in place. Testing should be performed with the boat in the
water, although you can initially confirm basic operation with the boat out
of the water.
1. Press POWER once to turn the control head on. If the unit does not
power up, make sure that the connector holder is fully seated in the
receptacle and that power is available.
2. If all connections are correct and power is available, the
Humminbird® control head will enter Normal operation.
3. If the bottom is visible on-screen with a digital depth readout, the
unit is working properly. Make sure that the boat is in water greater
than 2' but less than the depth capability of the unit, and that the
transducer is fully submerged, since the sonar signal cannot pass
through air.
NOTE: The transducer must be submerged in water for reliable transducer
detection.
4. If the unit is working properly, gradually increase the boat speed to
test high-speed performance. If the unit functions well at low
speeds, but begins to skip or miss the bottom at higher speeds, the
transducer requires adjustment.
5. If you have the correct angle set on the transducer, yet lose a bottom
reading at high speed, adjust the height and the running angle in
small increments to give you the ideal transducer position for your
boat. First, adjust the height in small increment.
Storing Excess Cable
22
Transom Mount - DualBeam PLUS™
NOTE: The deeper the transducer is in the water, the more likely that a rooster
tail of spray will be generated at high speeds, so make sure that the transducer
is as high as it can be and still be submerged in the water.
If you are still not getting good high speed readings, you may need
to disassemble the transducer mounting assembly and re-position
the ratchets.
If you do change the transducer position, re-trace the position of the
mounting bracket before proceeding.
NOTE: It is often necessary to make several incremental transducer adjustments
before optimum high speed performance is achieved. Due to the wide variety of
boat hulls, however, it is not always possible to obtain high speed depth
readings.
6. Once you have reached a consistently good sonar signal at the
desired speeds, you are ready to lock down the transducer settings.
Force the pivot to the Up position to gain access to the mounting
screws, then re-align the mounting bracket against the transom of
the boat to match the traced silhouette. Check the bracket position
with the level again to make sure it is still level, then mark the third

mounting screws and the transducer assembly and set aside.
7. Drill the third mounting hole, using a 5/32” drill bit. Use a marine-
grade silicone sealant to fill all three drilled mounting holes,
especially if the holes penetrated the transom wall.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce
the chance of chipping or flaking the outer coating.
8. Re-position the transducer assembly
against the transom of the boat, then
hand-install all three screws. Make
sure that the transducer location and
the pivot angle have not changed,
then fully tighten all three mounting

you have performed the preceding
procedures correctly, the transducer
should be level and at the right
height for optimal operation.

858c & 958c Inside the Hull Transducer Installation
DualBeam PLUS™ Transducer, XNT 9 20 T (858c and 958c only)
NOTE: Do NOT install the Side Imaging transducer inside the hull, as the side®
looking beams cannot penetrate the hull. Only the DualBeam PLUS™ transducer
can be mounted inside the hull.
If you choose to mount your transducer of your boat, performinside the hull
the procedures in this section. In-hull mounting generally produces good
results in single thickness fiberglass-hulled boats. Humminbird® cannot
guarantee depth performance when transmitting and receiving through the
hull of the boat, since some signal loss occurs. The amount of loss depends
on hull construction and thickness, as well as the installation position and
process.
NOTE: In-hull mounting requires an installed and operational control head.
NOTE: The integral temperature probe will not work with in-hull mounting, so
you may either want to consider purchasing a Temperature/Speed accessory, a
Temp. Sensor, or obtaining a different transducer. Humminbird® offers a
transducer exchange program to swap the NEW and UNASSEMBLED transducer,
accompanied by mounting hardware, for one without an integral temperature
probe. Call the Humminbird® Customer Resource Center at 1-800-633-1468 for
details, or visit humminbird.com for more information.
NOTE: Your transducer may not look exactly like the transducer shown in the
illustrations, but it will mount in exactly the same way.
There are several procedures you will have to perform in order to install a
transducer inside the hull. They are as follows:
• Locate transducer mounting location
• Perform a trial installation
• Route the transducer cable
• Permanently mount the transducer
1. Locating the transducer mounting location
Decide where to install the transducer on the inside of the hull. Consider the
following to find the best location:
• Observe the outside of the boat hull to find the areas that are mostly
free from turbulent water. Avoid ribs, strakes and other protrusions,
as these create turbulence.
• As a general rule, the faster the boat can travel, the further aft and
closer to the centerline of the hull the transducer has to be located
in order to remain in contact with the water at high speeds.
This installation requires slow-cure two-part epoxy. Do not use silicone
or any other soft adhesive to install the transducer, as this material
reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has
a tendency to cure before all the air bubbles can be purged, thus
reducing signal strength.
Inside the Hull Mount - DualBeam PLUS™
25 Inside the Hull Mount - DualBeam PLUS™
2. Trial installation
You will not be able to adjust the mounting after an inside the hull
transducer is installed. It is best, therefore, to perform a trial installation first
that includes running the boat at various speeds, in order to determine the
best mounting area before permanently mounting the transducer.
1. Plug the transducer into the control head, then power up the control
head. When the control head detects a functioning transducer, it
will automatically enter Normal operating mode.
2. View the sonar signal at its best by holding the transducer over the
side, immersed in the water, so that it is pointing straight down over
a known flat bottom. Use the display to benchmark against the
sonar signal that will be detected once the transducer is placed in
the hull.
3. Place the transducer body face down at the identified mounting
location inside the hull, with the end that has the mounting knuckle
pointed towards the bow of the boat.
4. Fill the hull with enough water to submerge the transducer body.
Use a sand-filled bag or other heavy object to hold the transducer in
position. The transducer cannot transmit through air, and the water
purges any air from between the transducer and the hull, and fills
any voids in the coarse fiberglass surface.
5. View the sonar signal on the display and compare against what you
observed in Step 2, making sure that the boat is in the same location
as it was during your observations in Step 2. If the results are
comparable, move on to Step 6. Otherwise, locate a new position in
the hull and repeat Steps 3 through 5.

6. Run the boat at various speeds and water depths while observing
the screen on the control head. If depth performance is required,
test the transducer in water at the desired depth. If the performance
is acceptable, move on to Step 7. If the performance is not
acceptable, repeat Steps 3 through 6.
7. Once you have determined the best mounting location using the
above steps, mark the position of the transducer.
3. Routing the cable
1. Once the mounting location is determined and you have marked the
position of the transducer, route the cable from the transducer to
the control head.
4. Permanently mounting the transducer
1. Make sure the position of the transducer is marked.
2. You may have to disconnect the cable to the control head and
reconnect it at the end of this procedure.
3. Remove the water from inside the hull and thoroughly dry the
mounting surface. If the surface is excessively rough, it may be
necessary to sand the area to create a smooth mounting surface.
4. Slowly and thoroughly mix an ample quantity of two-part slow cure
epoxy. Avoid trapping air bubbles.
5. Coat the face of the transducer and the inside of the hull with epoxy.
6. Press the transducer into place with a slight twisting motion to
purge any trapped air from underneath, keeping the end of the
transducer that has the mounting knuckle pointed forward, towards
the bow of the boat.
NOTE: Proper operation requires the end of the transducer that has the mounting
knuckle to face towards the bow of the boat.
7. Weight the transducer so that it will not move while the epoxy is
curing.
NOTE: When the epoxy cures, no water is necessary inside the hull.
8. If you unplugged the transducer cable at the beginning of this
procedure, plug it back into the control head.
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the
transducer.
29 Transom Mount - Side Imaging®
• The hydrodynamic shape of your transducer allows it to point straight
down without deadrise adjustment.
• On boats with stepped hulls, it may be possible to mount the trans-
ducer on the step. Do not mount the transducer on the transom
behind a step to avoid popping the transducer out of the water at
higher speeds; the transducer must remain in the water for the
control head to maintain the sonar signal.
• If the transom is behind the propeller(s), it may be impossible to find
an area clear from turbulence, and a different mounting technique or
transducer type should be considered (see Trolling Motor
Transducer Installation).
• The Side Imaging® transducer must NOT have anything obstructing
the ‘view’ of the side looking beams, i.e. nothing can be in the line
of sight of these beams (not a hull, motor, or other transducer, etc).
Mounting the transducer bracket to the boat
1. Remove the transducer mounting template from this manual. See
Appendix A for the Transducer Mounting Template.
2. Hold the template on the transom of the boat in the location where
the transducer will be installed. Align the template vertically,
matching the lower edge of the transom with the bottom corner of
the template. If your propeller moves clockwise as the boat moves
forward, mount the transducer on the starboard side, and use the
bottom left corner of the template. If your propeller moves counter-
clockwise as the boat moves forward, mount the transducer on the
port side, and use the bottom right corner of the template.
3. Using a pencil or punch, mark the three mounting holes on the
transom. Do not mark or drill any other holes at this time.
4. Using a 5/32" (4.0 mm) bit, drill the three holes to a depth of
approximately 1" (25 mm). On fiberglass hulls, it is best to use
progressively larger drill bits to reduce the chance of chipping or
flaking the outer coating. Use a marine-grade silicone sealant to fill
the drilled holes.

5. Align the metal mounting bracket with the mounting holes. The center
slot should be above the two outer slots. (This bracket and all other
hardware supplied is top quality stainless steel for maximum strength
and corrosion protection.) Insert the three #10 - 1" long screws into the
drilled holes, but do not completely tighten.
Attaching the pivot to the transducer
1. Attach the pivot to the transducer body, using the two 1/4"-20 x 5/8"
(16 mm) machine screws, toothed washers, and square nuts. The
toothed washers must fit on the inside of the transducer ears,
between the pivot and the ears. The square nuts will be prevented
from rotating by the pocket in the back of the pivot. An Allen wrench
is provided which fits all the 1/4"-20 screws, but do not fully tighten
the screws at this time.
Mounting the transducer pivot assembly to the bracket
1. Slide the assembled transducer into the metal bracket from the
bottom, aligning the large hole at the top of the bracket with the
hole in the pivot.
2. Insert the headed pin through the pivot holes in the bracket and
pivot. The headed pin can be inserted from either side of the
bracket.
3. Place the nylon washer over the opposite end of the headed pin.
Place the stainless washer over the 1/4"-20 x 5/8" (16 mm) screw
threads, then insert into the opposite end of the headed pin and
finger tighten only. The screw has a thread locking compound on the
threads to prevent loosening, and should not be fully tightened until
all adjustments are made.
NOTE: The running position of the transducer is now completely adjustable.
Subsequent adjustment may be necessary to tweak the installation after high
speed testing.

Adjusting the running position of the transducer
The transducer mounting bracket allows height and tilt adjustment, while
the pivot bolt allows angular adjustment. These adjustments will help
reduce cavitation. Initially, adjust the transducer as described in the
following paragraphs. Further adjustment may be necessary to refine the
installation after high-speed testing.
1. First, adjust the pivot angle of the transducer body, so it is parallel
with the length of the hull of the boat.
2. Fully tighten the two pivot screws, using the supplied Allen wrench.
Access to the pivot screws is provided by the lower holes in the side
of the mounting bracket. It may be necessary to re-tighten the pivot
bolt after initial use as the plastic may still be conforming to the
pressure from the lock washers.
3. Adjust the height of the assembly so the face
of the transducer is 1/8" (3 mm) to 1/4" (6 mm)
beneath the bottom of the transom, and fully
tighten the three mounting screws.
4. In order to gain access to the mounting
screws, the transducer assembly must be
pivoted up in the bracket as shown. Be careful
not to alter the running angle as some force is
necessary to pivot the assembly.
5. If access to the top mounting hole is not possible due to the selected
height of the transducer, fully tighten the two lower screws, then
simply remove the headed pivot pin and the transducer assembly,
and tighten the top screw, then reassemble.
6. Confirm that the pivot angle has not changed and that all mounting
screws are fully tightened.

33 Test & Finish Transducer Installation
Trolling Motor Transducer Installation
Several styles of the transducer are compatible with trolling motor mounting.
If you have a trolling motor bracket, refer to the separate installation
instructions that are included with the bracket.
NOTE: After trolling motor transducer installation, please perform the final
testing and then finalize the installation (see Test and Finish the Transducer
Installation).
Trolling Motor Transducer Options
If you don’t have a trolling motor transducer,
there are several options:
• You may purchase a Trolling Motor Adapter kit
that will allow you to mount the transducer on the
trolling motor.
• You may also exchange your NEW and UNASSEMBLED transducer
(with mounting hardware included) for a trolling motor transducer.
There are also several transducer switches available that support the
following configurations:
• Two control heads with one transducer
• Two transducers with one control head.
NOTE: 1-800-633-1468Call the Humminbird® Customer Resource Center for
details and pricing, or visit humminbird.com for more information.
Test and Finish the Transducer Installation
When you have installed both the control head, the transducer, and
accessories, and have routed all the cables, you must perform a final test
before locking the transducer in place. Testing should be performed with the
boat in the water, although you can initially confirm basic operation with the
boat out of the water.
1. Press the POWER/LIGHT key once to turn the control head on. There
will be an audible chirp when the key is pressed correctly. If the unit
does not power-up, make sure that the connector holder is fully
seated and that power is available.
2. If all connections are correct and power is available, the control
head will enter Normal operation. If no transducer is detected (or
one is not connected), the unit will go into Simulator mode and will
indicate this by displaying the word Simulator on the control head
display.
NOTE: The transducer must be submerged in water for reliable transducer
detection.
3. If the bottom is visible on-screen with a digital depth readout, the
unit is working properly. Make sure that the boat is in water greater
than 2 ft (.6 m) but less than the depth capability of the unit, and
that the transducer is fully submerged, since the sonar signal
cannot pass through air.
35 GPS- Stem Mount
Stem Mounting with an Existing 1" - 14 Thread Stem
Follow these steps to stem mount the GPS receiver:
NOTE: If you have an existing stem for mounting the GPS receiver, proceed
directly to step 2 of the following procedure.
1. Determine the best location to mount your GPS receiver. Preplan
and test the cable routing to your control head before any drilling or
cutting of your boat surfaces. If you have purchased hardware to
stem mount your GPS receiver, follow the instructions included with
that hardware to mount the stem (antenna pole).
NOTE: AS-EC10 10' extension cables are available from Humminbird® if your
planned routing exceeds 20', (6 m). Maximum cable length, including extensions,
should not exceed 50' (16 m).
NOTE: Remember to caulk or seal screw holes and drilled holes as needed to
protect your boat from water damage.
2. Screw on the receiver base to the stem
first, making sure that the stem pipe
does not protrude from the receiver
base. This adds protection to the cable
when pulling it through the pipe stem.
In addition to this, de-burr the pipe
edges to reduce cable abrasion.
3. Use electrical tape to secure the NMEA pigtail to the cable as
shown.
NOTE: Leave the NMEA pigtail secured to the cable unless needed. This will
make removing the receiver easier.
4. Route the GPS receiver cable through the stem and continue with
the planned route you chose in step 1.
5. Attach the GPS receiver to its base using the included #6 - 7/8"
screws.

Access Under Mounting Location
Follow these steps to deck mount the GPS receiver when routing the cable
down through the mounting location:
1. Determine the best location, then test route the 20' (6 m) cable from
the mounting location to the control head.
NOTE: Installation details may vary with unit configuration.
2. Mark the mounting location and drill a 3/4" (19 mm) hole for the
cable and cable plug. Route the cable.
3. Cover the cable hole with the receiver. Make sure the receiver is
flush on the surface and mark the two mounting holes with a pencil
or punch.
4. Move the receiver to the side and drill two pilot holes using a 9/64"
(3.5 mm) bit.
NOTE: Remember to caulk or seal screw holes and drilled holes as needed to
protect your boat from water damage.
5. Align the GPS receiver screw holes over the pilot screw holes and
attach with the #8 - 1 1/4" Phillips head screws. Hand tighten only!
NOTE: If the mounting surface is thin and made of a lighter material, a backing
material may be needed below the mounting surface.
No Access Under Mounting Location
Follow these steps to deck mount the GPS receiver in a situation where you
must route the cable to the side because there is no space for a cable
underneath the mounting location.
1. Determine the best location, then test route the cable from the
mounting location to the control head.
NOTE: AS-EC10 10' extension cables are available from Humminbird® if your
planned routing exceeds 20', (6 m). Maximum cable length, including extensions,
should not exceed 50' (16 m).
2. Confirm the cable length is good and route the cable from the
receiver to the control head. If holes are required to route the cable,
they must be 3/4" (19 mm) to allow for the cable connector. Secure
the NMEA pigtail with electrical tape.
NOTE: Remember to caulk or seal screw holes and drilled holes as needed to
protect your boat from water damage.

3. The GPS receiver has two wire routing notches. Use the cable notch
closest to the intended cable route.
4. With the cable routed, position the GPS receiver in the planned
mounting location and mark the mounting holes with a pencil or
punch.
5. Move the GPS receiver to the side and drill the two 9/64" (3.5 mm)
pilot holes.
6. Align the GPS receiver's screw holes over the pilot screw holes and
attach with the #8 - 1 1/4" Phillips head screws. Hand tighten only!
Finish Routing the Cable and
Check GPS Receiver Operation
After installing a GPS receiver, you should perform the following procedure
to finish routing the GPS cable to the control head and to check to make sure
that the control head is working correctly.
1. Secure the cable along its path to the control head as needed with
cable ties.
2. Plug the GPS receiver cable into the Communications port on the
control head. See Testing the System Installation to use the

What’s on the Side Imaging® Display
What’s on the Side Imaging® Display
(898c SI and 998c SI only)
Side Imaging® displays a number of easily recognizable features that allow for accurate interpretation of bottom contour and structure. For Side Imaging®
composition determines the intensity of the sonar return. For example, rock and gravel provide a clearer sonar return than mud and sand because of their
density. Upward slopes that face the transducer reflect sonar better than downward slopes that face away from the transducer. You can find a number o
recognizable features on the Side Imaging® display that allow for accurate interpretation of bottom contour and structure, including the following items:
Side Imaging® Range - Images shown on the right side of the
screen are located on the right side of your boat, and images
shown on the left side of the screen are located on the left side
of your boat. In this illustration, the sonar is pinging 148 feet
on each side.
Topography Changes - The light part of the screen shows
where the beam is hitting hard bottom or rising terrain. The
dark part of the screen indicates soft bottom (sand, mud) or
descending terrain.
Depth - Water depth; can be set to alarm when the water becomes too shallow.
1
Timer - Elapsed time with Speed accessory or GPS Receiver.
Water column - Shows the relative depth of the water under
the boat at a given time. Variations in the width of the water
column show variations in the distance to the bottom as the
boat passes over.
2
Distance - Distance traveled with Speed accessory or GPS Receiver.
3
Average Speed - Average speed reading with Speed accessory or GPS Receiver.
4
Shadows - Result from a lack of reflected sonar from a particular
area and can be more valuable for interpretation than the sonar
reflected by the object itself. Use shadows to help you see the
image in 3 dimensions, oriented in space. You can gain insight
into the actual shape of an object, or the depth to which it has
sunk into the bottom, through shadows on the display. Objects
standing on the bottom cast a sonar shadow. The longer the
shadow, the taller the object. Fish also cast shadows. You can
use the shadow to interpret how close the fish is to the bottom.

What’s on the Side Imaging® Display
Side Imaging® Frequencies and Coverage
Side Imaging® sonar uses two very precise sonar beams that are directed to
either side of the boat. The beams “illuminate” the bottom contour,
structure, and fish, and the results are displayed in a “picture-like” image on
the screen.
• Frequencies: The side beams can be operated at one of two
frequencies: 455 kHz or 800 kHz. Your Side Imaging® transducer also
provides DualBeam PLUS™ at 200/83 kHz. Selecting 800 kHz
produces the sharpest image, while selecting 455 kHz provides
greater bottom coverage area.
• are extremely narrow from front to back, andSide Imaging® Beams
provide “thin slices” of the bottom for high resolution imaging.
• 240 feet to each side, with a total sideSide Imaging® Range:
coverage of 480 feet, with a depth limitation of 150 feet, depending
on the contour of the bottom and when the side beam frequency
selection is set to 455 kHz.
800 kHz provides highest resolution with 130° total beam width
455 kHz provides maximum coverage with 180° total beam width
