If any of these items is missing, contact your local distributor.
ACCESSORIES
Humminbird offers a wide assortment of accessories that complement and
expand the capability of your new 150SX. These accessories are designed
with the same high standards and are backed by the same one-year
warranty. The Humminbird Accessory catalog included with your unit
contains descriptions of the many accessories available and ordering
information. All Humminbird accessories are available through your full-
service Humminbird dealer or factory direct through our number listed in
the Customer Support section.
INSTALLATION OVERVIEW
The 150SX consists of two primary components to install: the control head
and the transducer.
The control head contains the sonar transmit and receive circuitry, as well
as the user controls and display. It should be installed in a location that
provides access to the controls and visibility while in use. The control head
mounts on a quick disconnect mounting system that swivels and tilts
providing flexibility for viewing from almost anywhere on the boat.
The transducer converts electrical energy from the transmitter into
mechanical pulses or sound waves. The transducer also receives the
reflected sound waves and converts them back into electrical signals for
display on the control head. It should be installed in contact with the

INSTALLATION OVERVIEW
surface of the water in an area that has smooth water flow - usually on the
transom of the boat. There are several mounting options for the
transducer. Review the following section to determine the method that
works for you and your boat.
Determining How to Mount the Transducer
The 150SX includes a model XHS-6-24 transducer. This transducer can be
mounted on the transom of the boat, or
bonded to the inside of a fiberglass hull
boat.
The transom installation, which is the
most widely used, places the transducer
on the outside of the boat hull. This
technique produces the least signal loss,
and provides a way to adjust the
transducer after installation. The
mounting hardware included is designed
to protect both the boat and the
transducer should the boat strike debris
in the water or when trailering.
As an alternative to transom mounting, it is possible on many fiberglass-
hulled boats to glue the transducer on the inside of the boat hull. Since
fiberglass has similar sonar character-
istics as water, the sonar signal can
pass through the boat hull with
minimal loss. The hull of the boat
must be single layer construction
(not double-hulled). Also, any air
trapped in the lamination of the
fiberglass would prevent the sonar
signal from passing through.
Transom Mounted Transducer
Inside the Hull Mounted Transducer
For additional details reference the
TRANSDUCER INSTALLATION section of
the enclosed Installation Sheet.

Inside the hull installations require no holes be drilled into the boat and
through experimentation, high-speed operation comparable to transom
mounting can be achieved. Two part, slow cure epoxy is required to glue
the transducer in place.
ALTERNATE TRANSDUCERS AND MOUNTING METHODS
The 150SX comes with everything necessary for installation and operation
on most boats. However, there are several situations which may require a
different type of transducer. Inboard boats, wood or metal hulls, and sail
boats create unique transducer mounting needs. Alternate transducers and
mounting methods are detailed below.
Portable Mounting
The standard transducer can be adapted for
portable installations using part number MHX-
PT2. This accessory adapts your transducer to a
suction cup mount for temporary installation on
the boat hull or other surface.
Trolling Motor Mounting
The standard transducer can also be adapted to
mount on most trolling motors using part
number AD-STM-7. This accessory includes a
bracket and hose clamp that allows mounting
the transducer to the body of most trolling
motors.

ALTERNATE TRANSDUCERS AND MOUNTING METHODS

TRANSDUCER EXCHANGE
Other transducers are available as replacements for the standard
transducer. You may exchange your new and unassembled transducer for
another type by returning it to the address listed in Customer Support.
Some transducers may have additional costs. Refer to the Accessory cata-
log or call Customer Support for information.
BEGINNING INSTALLATION
Now that you have determined the transducer mounting method, you can
begin installation of the 150SX. The fold out installation guide included
provides detailed step by step instructions for installation of the control
head and transducer. For transom mount transducer installations, you will
need the mounting template at the back of this manual.
In addition to the parts included you need the following for installation and
operation:
•A powered hand drill and various drill bits
•Phillips and flat-head screw drivers
•A ruler or measuring tape
•Pen or pencil
•12 volt power source (your boat’s battery)
•A 1-amp fuse
•A fuse holder (if you are wiring directly to the boat’s battery)
•Silicone sealant (for sealing drilled holes)
•2-part, slow-cure epoxy (for inside the hull transducer installations)

USING THE 150SX
HOW SONAR WORKS
6
HOW SONAR WORKS
Your Humminbird unit uses sonar to
locate and define underwater objects,
define the bottom terrain, as well as
determine distance.
Sonar technology is based on sound
waves. Your Humminbird unit sends
out a sound wave signal. With this
signal it determines distance by
measuring the time between the
transmission of the sound wave and
when the sound wave is reflected off
an object. Your Humminbird 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' (70m) and back again in less than ¹⁄₄ of a second. It is unlikely that
your boat can "outrun" this sonar signal.
The 150SX is a 200 kHz, single-beam fishfinder. The 200 kHz frequency
provides excellent sonar resolution (the ability to distinguish small returns
or returns which are close to the bottom), while providing depth
capabilities to 600’(185m). The shape of the sonar beam is symmetrical
and covers an area of approximately 24 degrees side to side and front
to rear.
Actual depth capability depends on factors such as bottom hardness, water
conditions, and transducer installation. Units will typically read to deeper
depths in fresh water than in salt water
SIMULATOR OPERATION
The 150SX contains a simulator that allows you to use the unit as if you are
on the water. The simulator is invaluable for learning how to operate the
150SX.

7
USING THE 150SX
SIMULATOR OPERATION
There are two ways to start the simulator. If
the unit is powered off, press and hold the
POWER button for approximately three
seconds until you hear a continuous chirp.
The simulator can also be started by
selecting the Simulator option on the start-
up screen after you power-up the unit.
When this screen is shown, simply press the DOWN ARROW until
“Simulator”is highlighted. When the screen times out, the unit will be in
simulator mode.
When in simulator operation, the 150SX responds to control inputs as if it
is in actual operation, so feel free to experiment, or to customize the unit
for your particular operation.
To exit Simulator mode, power the unit off.
When in simulator mode, the word “simulator” occasionally
scrolls across the display indicating the information on-screen is
not real sonar data.
FEATURE MEMORY
If your 150SX is installed with a transducer connected, any changes you
make to the set-up or User Options (see Control Functions) while in
Simulator are retained in the unit’s memory. This allows you to use
simulator to experiment with the various set-up options, and retain your
selected settings for normal operation.
If you are using the 150SX in Simulator when no transducer is connected,
any selected options are lost when the unit is powered off. The 150SX will
return to Factory Settings, or options selected when last used with a
transducer, if no transducer is connected.
IMPORTANT: A transducer must be connected to the 150SX in
order to retain user settings selected when in simulator mode. If
no transducer is detected, the unit defaults to pre-selected
options when powered off.

What You See On-Screen
Your 150SX uses a 128 V x 64 H matrix FSTN LCD display. This display
provides outstanding viewability in all light conditions over a wide range of
temperatures.
At initial power-up, the 150SX uses settings that were set at the factory.
After initial use, the 150SX will remember the settings you enter.
There are several elements on-screen that are common to all modes of
operation.
Depth. The digital depth number shows the water depth directly beneath
the transducer location.
Depth Range. The depth range is shown to the right of the screen. The upper
number is 0 indicating the surface of the water. The lower number is one of the nine
depth ranges available that best match the depth of the water. As the depth of the
water changes, the range changes as necessary in order to retain a bottom
representation on-screen.
When in Auto mode, the horizontal line at the top of the screen is the “zero line,”
representing the surface of the water. Occasionally there is a gap in this line. This gap
indicates the unit is updating the
display even if the bottom is not visible
on-screen, or if the bottom information
is not changing.
New sonar information appears on the
right side of the graphic area of the
display and moves to the left as new
information is displayed. The 150SX
automatically selects the appropriate
depth range to show the depth of
water beneath the transducer. This
range is selected so the bottom
representation is typically shown about
²⁄₃ down the display.
