INSTALLATION OVERVIEW

The 105SX 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 105SX 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.

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 characteristics 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

Inside the hull installations require no holes be drilled into the boat and through experimentation, highspeed operation comparable to transom mounting can be achieved. Two part, slow cure epoxy (not included) is required to glue the transducer in place.

INSTALLATION PREPARATION

ALTERNATE TRANSDUCERS AND MOUNTING METHODS

The 105SX 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-SPT. 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. This accessory includes a bracket and hose clamp that allows mounting the transducer to the body of most trolling motors.

Thru-Hull Mounting

Thru-hull transducers install through a hole drilled in the hull of the boat. Larger boats or boats with inboard motors create turbulence that make transom mounting ineffective. Also, hulls that are very thick or are double layered, or made from materials such as wood or metal, (which do not conduct sonar signals) make inside the hull mounting inadvisable.

Thru-hull mounting may require the use of a fairing block to level the transducer with the waterline. Also, since special tools and knowledge may be required to perform this type of installation it is best to refer to a qualified marine technician.

INSTALLATION PREPARATION

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 catalog or call Customer Support for information.

BEGINNING INSTALLATION

Now that you have determined the transducer mounting method, you can begin installation of the 105SX. 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 in the center 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 105SX

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 600' (185m) and back again in less than that your boat can "outrun" this sonar signal.

The 105SX is a 200kHz, 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

USING THE 105SX

SIMULATOR OPERATION

The 105SX 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 105SX.

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 startup 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 105SX 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” will flash on and off in the top center part of the display.

FEATURE MEMORY

If your 105SX is installed with a transducer connected, any changes you make to the set-up 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.

USING THE 105SX

WHAT YOU SEE ON-SCREEN

If you are using the 105SX in Simulator when no transducer is connected, any selected options are lost when the unit is powered off. The 105SX 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 105SX 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 105SX uses a 128 x 64 matrix FSTN LCD display. This display provides outstanding viewability in all light conditions over a wide range of temperatures.

At initial power-up, the 105SX uses settings that were set at the factory. After initial use, the 105SX will remember the settings you enter.

There are several elements on-screen that are common to all modes of operation.
