Page 2: Installation Preparation
Customer Support section. INSTALLATION OVERVIEW Your Humminbird fishfinder 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. - Page 3 INSTALLATION PREPARATION Determining How to Mount the Transducer Your Humminbird fishfinder includes a standard 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.
- Page 4 ALTERNATE MOUNTING METHODS ALTERNATE TRANSDUCERS AND MOUNTING METHODS Your Humminbird fishfinder 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.
- Page 5 BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder. The installation guide included on the next few pages 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 included with your manual.
- Page 6 Do not begin this transducer installation until you read the Installation Preparation in the Operation Guide. This chapter contains information critical to the correct installation of your transducer. Due to the wide variety of boat hulls, only general instructions are presented in the installation guide.
- Page 7 If the propeller(s) is (are) forward of the transom, it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered. Step Two - Drill the Mounting Holes 1. Remove the mounting template from the front of the Operations Manual. 2.
- Page 9 Step Four - Mount the Transducer to the Transom 1. Apply silicone sealant to the mounting holes drilled into the transom. 2. Align the transducer assembly with the drilled holes in the transom (Figure 8). 3. Use either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm) socket to mount the assembly.

- Page 11 If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50' (15 m). Call Humminbird Customer Support for more information. Follow these steps to route the cable through the transom: 1.
- Page 12 Inside the 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, and the installation.
- Page 13 The transducer cannot transmit through air. The water purges any air from between the transducer and the hull and fills any voids in the coarse fiberglass surface.
- Page 14 3. Power up the Control Head. 4. Run the boat at various speeds and water depths while observing the screen on the Control Head. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fishfinder in water at the desired depth.
- Page 15 CONTROL HEAD INSTALLATION Step One - Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine best location: The cables for power, transducer and temp/speed accessories (if applicable) should be installed first and must reach the mounting location. Extension cables are available.

- Page 17 (not included) for the protection of the unit (Figure 21). Humminbird is not responsible for over voltage or over current failures. In order to minimize the potential for interference with other marine electronics a separate power source (such as a second battery) may be necessary.
- Page 18 Optional: If the cables pass outside the mounting bracket, install the hole cover over the hole and fasten in place using the two #8 x 7/8” (22mm) wood screws (Figure 24).
- Page 19 5. Install the control head by sliding it onto the mounting bracket until it is fully seated. To remove the unit simply depress the latch on the rear of the unit and lift (Figure 29). Your Humminbird is now ready for operation. INSTALLATION CONTROL HEAD INSTALLATION...
- Page 20 Note: it is often necessary to make several incremental transducer adjustments before optimum high-speed performance is achieved. Important: For Transom Mount transducer installations, install the third mounting screw after the final transducer adjustments. Humminbird 3 Humminbird Lane Eufaula, Alabama 36027...
- Page 21 When the screen times-out, the unit will be in simulator mode. When in simulator operation, the 100SX responds to control inputs as if it is in actual operation, so feel free to experiment with the many features and functions to customize the 100SX for your particular operation.
- Page 22 The best way to learn to interpret structure is to operate the 100SX over a variety of known conditions and experiment with user functions to best represent those conditions on-screen.
- Page 23 The 100SX uses advanced signal processing to further evaluate any sonar return between the surface and the bottom. For instance, a small school of bait fish usually appears as a dense cluster of individual dots.
- Page 24 The backlight is very effective for low-light and nighttime operation. When the backlight is on, the 100SX will consume more power than with the backlight off. This is important when using the 100SX in a portable configuration powered by a separate battery, or when powering the unit from a trolling motor battery.
- Page 25 Sensitivity The Sensitivity function controls the sensitivity of the sonar receiver. The 100SX automatically adjusts the level of receiver sensitivity based on a number of factors including the depth of the water and the level of noise present. Noise can be caused by other electronic devices, engines, trolling motors, propeller cavitation and hydrodynamic flow among others.
- Page 26 ARROW button. The button press will bring the Depth Range menu on-screen and allows immediate adjustment of the range. The 100SX automatically adjusts the depth range depending on the depth of the water. The unit tries to maintain the bottom depiction about 2/3 down the total range (for example, in 20' (6m) of water, the 0-30' (0103) range would be selected).
- Page 27 To return to "Automatic" Depth Range control, press the MENU button until the Depth Range menu appears on-screen and use the UP ARROW to select AUTO. The 100SX returns to Automatic operation. Zoom Zoom is similar to Depth Range in that it controls the range of information displayed in the graphics area of the display.
- Page 28 "On". Use the DOWN ARROW to highlight "On" and the menu further expands to show the 3 alarm options. The selected setting will be "Large fish only". With this setting, the 100SX alarms on only those targets which are represented by the large fish symbols (see Interpreting the On- Screen Information).
- Page 29 Selecting ID Off will also disable the Fish Alarm if selected. ID On enables the 100SX to interpret the raw sonar data and using a variety of techniques, depicts appropriate returns as one of three different size fish symbols.
