1100 Series™ Introduction
Your 1100 Series™ Ultra Wide Screen Fishing System comes in several different configurations.
See the following list of products, all of which are covered by this manual, to find your
1100 Series™ configuration:
• Humminbird® 1158c Combo: Ultra wide screen Fishing System with DualBeam PLUS™
sonar and chartplotting. GPS receiver included.
• Humminbird® 1198c SI Combo/1198c SI Combo NVB: Ultra wide screen Fishing
System with Side Imaging® Sonar, DualBeam PLUS™ Sonar, and chartplotting. GPS
receiver included.
How Sonar Works
Sonar technology is based on sound waves. The 1100 Series™ Fishing System uses sonar to
locate and define structure, bottom contour and composition, as well as depth directly below
the transducer.
Your 1100 Series™ 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.
1
Introduction
When all the echoes are viewed side by side, an easy to interpret
"graph" of the bottom, fish, and structure appears.
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.
Introduction
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.

(1198c SI Combo models only)
Your 1198c SI Combo uses 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 455 kHz.
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 the
Side Imaging® Display for more information.
DualBeam PLUS™ Sonar (1158c, 1198c SI)
Your 1100 Series™ 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.
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.
Universal Sonar 2
Your 1100 Series™ Fishing System supports Universal Sonar 2, a state-of-the-art, integrated and
protected transducer that is built into the lower unit of Minn Kota® trolling motors. With
Universal Sonar 2, all wiring is concealed inside the indestructible composite shaft—out of
sight and out of harm’s way, with no clamps, ties, or exposed wires. Universal Sonar 2 features
new temperature sensing and the performance of DualBeam PLUS™ technology. An expanded
view and greater bottom detail gives you a totally new perspective of the water below, along
with optimal sonar performance to help you find fish.
Introduction
4
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 +/- 4.5 meters, depending on conditions.
This means that 95% of the time, the GPS receiver will read a location within 4.5 meters of your
actual position. Your GPS Receiver also uses information from WAAS (the Wide Area
Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and
MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area.
The following GPS functionality is currently supported by the Fishing System 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
See Chart View and SD Memory Card Slots: Add Maps to Your Fishing System for more
information.

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 should not be cut, and care should be used not to damage the cable insulation.
Basic installation tasks that you must perform include the following:
• Installing the control head (choose gimbal or in-dash mounting)
• Installing the transducer (choose the installation method that matches your transducer)
• 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 1100 Series™ 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 In-dash mounting.
Gimbal Mounting the Control Head
If you are gimbal mounting the Humminbird® 1100 Series™, you can pre-assemble the unit in
order to plan the best mounting location.

Installation - Gimbal Mount
1. Place the control head into the gimbal bracket. Make sure that the straight side of the
gimbal arm is against the back side of the control head.
2. Place a 1" (25 mm) diameter black washer on the gimbal knob and then thread the knob
and washer into the housing. Tighten the gimbal knob to secure the control head to the
mount. Repeat step 2 for the other side.
You can now place the control head in various locations to decide which is best for mounting.
Rotating the mounting bracket to the top of the control head will allow for overhead mounting.
The chosen mounting area should allow for sufficient room so the control head can pivot
through the full tilt range and allow for easy removal and installation.
NOTE: You can drill the cable pass hole underneath the gimbal bracket, allowing you to thread the cables
through the hole in the center of the mount; however, if you cannot drill the hole directly under the
mounting bracket, then you willneed to drillthe cable pass hole behindthe bracket, and will need to mount
the hole cover there instead.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use progressively
larger drill bits toreduce the chance ofchippingor flaking the outer coating. Fill allholes with marine grade
silicone sealant.
NOTE: You must have underside access to the mounting location to pass the cables through to the surface.
Also, make sure that the mounting surface is adequately supported to protect the control head from
excessive wave shock and vibration and provide visibility while in operation.
NOTE: Go to the installation instructions applicable to your GPS Receiver and accessories. Make the
required installations and then run the cables to your control head mounting location. Do not cut any
cabling (exceptthe power cable). If yourcablesare too short, extensionsare availablefrom your local dealer
or online from humminbird.com.
3. After the mounting location has been determined, loosen the gimbal knobs and remove
the control head from the gimbal bracket.
NOTE: Alternate hole patterns are available on the gimbalmountingbracket, and may match existingholes
on the boat. You may choose to use one of these 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.

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 gimbal over the mounting surface hole, then
use it to mark the position of the two mounting screws, closest to the center large hole.
Remove the gimbal and drill the two mounting holes using a 9/64" (3.5 mm) bit. Do not
install the hole cover at this time. or...
6b. If the cables cannot be routed directly beneath the mounting bracket, mark and drill a
1" (25 mm) hole that will allow you to run the cables close to the bracket. Pass the
cables through the 1" (25 mm) hole, routing the cables through the grommet and
pressing the grommet into place. Place the hole cover over the mounting surface hole,
then use it to mark the position of the two mounting screws. Remove the hole cover,
drill the two mounting holes using a 9/64" (3.5 mm) bit, fill them with marine-grade
silicone sealant, then replace the hole cover and insert the #8 Phillips countersink wood
screws. Hand-tighten only.
7. Place the mounting bracket on the mounting surface aligned with the drilled holes and
fill the mounting holes with marine grade silicone sealant. Insert the four #10 SlottedHex wood screws into the mounting holes. Hand-tighten only.

8. If the cable pass through hole is beneath the mounting bracket, you will need to install
the hole cover after you have routed all cables. Place the hole cover over the mounting
bracket cable pass thru hole and align with holes drilled in step 6a. Insert the #8 Phillips
countersink wood screws. Hand tighten only.
NOTE: Be sure that the cables pass through the slots on the hole cover and that there is enough cable
slack to allow for the control head to pivot through its full tilt range. Extra cable slack will also help when
connecting or disconnecting the cables.

Connecting the Control Head Power Cable to the Boat
GROUNDGROUND
POSITIVEPOSITIVE
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 failures.The controlhead must have
adequate protection through the proper selection and installation of a 3 Amp fuse.
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not
included) that match the terminal on the fuse panel. Attach the black wire to
ground (-), and the red wire to positive (+) 12 VDC power. Install a 3 Amp fuse
(not included) for protection of the unit. Humminbird® is not responsible for
over-voltage of over-current failures.
or...
1b. If you need to wire the control head directly to a battery, obtain and install
an inline fuse holder and a 3 Amp fuse (not included) for the protection of the
unit. Humminbird® is not responsible for overvoltage or over-current failures.
NOTE: Your unit will detect when your battery voltage is too low or too high, and will display
either Input Voltage Low or Input Voltage High messages if these limits are exceeded. If you
turn the Low Battery Alarm on using the Alarms Main Menu, your unit will use your settings.
If you do not turn the Low Battery Alarm on, the unit will use these limits: 7.5 to 7.9 VDC for
the low end, and 21 to 21.2 VDC for the high end.
NOTE: In order to minimize the potential for interference with other marine electronics, a separate power
source (such as a second battery) may be necessary.
