Introduction The Fishfinder 100 is able to display a variety of useful information about the underwater environment. Below are a few things the unit will help you see. Water Depth What can the Fishfinder 100 Display? The unit displays water depth and can provide a warning for shallow or deep-water conditions. Battery Voltage* The unit can display the battery voltage that is available to the unit. Water Temperature* If equipped with a capable transducer, the unit can display the water temperature.
Transducers The transducer acts as the eyes and ears of your new sonar. Proper transducer selection and installation are critical to the operation of your unit. The transducer transmits sound waves toward the bottom in a cone shape. The larger the cone angle the larger the coverage area at a given depth. While it is good to see as large of an area as possible, it is best to select a transducer that suits the water that you are on. A wide cone angle transducer works best in shallow water.
Proper transducer installation is key to getting the best performance from your new unit. If the transducer lead is too short, extension cables are available from you GARMIN dealer. DO NOT cut the transducer lead, this will void your warranty. Following are some tips and basic installation instructions for three popular transducers. Detailed installation instructions are provided in the transducer kits.
In-hull Installation The 010-10224-00 transducer is designed to be mounted inside a fiberglass hull. The standard plastic transom mount transducer can also be mounted in this fashion using this method. If using a temperature sensing transducer, the temperature displayed will reflect the hull temperature. Selecting a Location Installation Mounting the Transducer 1. The location has to be solid fiberglass, devoid of any air bubbles, laminates, fillers or dead air space.
Trolling Motor Installation Installation Included in the 010-10251-00 transducer kit you should have: 1. Worm Gear Clamp 2. Cable Ties Mounting the Transducer 3. Transducer Mounting the Transducer: 1. Loosen the Worm Gear Clamp until end of the band is clear of the worm gear. Cable Ties 2. Slide the clamp band through the slots on the transducer. 3. Place the free end of the clamp band into the worm gear and tighten until the band is through the worm gear. Worm Gear Clamp Band 4.
Wiring Harness Installation The Fishfinder 100 comes with a wiring harness that connects the unit to power and the transducer with one easy-to-remove connection. Make sure the wiring harness will reach the unit before beginning installation. If it is necessary to extend the power/data wires, use a wire of comparable size and keep your extension as short as possible. If the transducer lead is too short, DO NOT cut the transducer lead to lengthen the cable. This will void the warranty.
Wiring Harness Installation (continued) Installation Installing the Wiring Harness If your boat does not have a fuse block, the unit can be wired directly to the battery. Make sure the 2-Amp in-line fuse supplied with the unit is installed. The Fishfinder 100 can be connected to another piece of NMEA compatible electronic equipment. If equipped with a capable transducer, the Fishfinder 100 sends depth, temperature and speed information that could be displayed on another device.
Display Installation (Surface Mount) The Fishfinder 100 can be mounted to a flat surface using the supplied Surface Mounting Bracket. Surface Mounting the Display: Installation Installing the Display 1. Position the Surface Mount in the desired location. Leave approximately 2'’ behind the unit for cable clearance. 2. Mark the location of the four mounting holes with a pencil. 3. Drill pilot holes for the mounting fasteners (not included in kit). 4. Secure the Surface Mount, using the mounting fasteners.
Display Installation (Flush Mount) Installation The Fishfinder 100 can be mounted flush against the dash or electronics rack that is no more than 1/4” thick. Flush Mounting the Display: Installing the Display 1. Remove the Surface Mount Bracket and Knobs. 2 Cut a 4.3”W x 4.35”H relief hole where the unit will be mounted. 3. Place the display in the relief hole and tape in place. 4. Reinstall the knobs in the unit. Install the surface mount with the cam lobes pointed toward the unit. 5.
Testing the Installation While it is possible to perform some checks with the boat trailered, to properly test the installation the boat should be in the water. Press the Power button and the Fishfinder 100 should power on. If the unit fails to power on, verify that the wiring adapter is seated properly in the back of the unit, the Red and Black wires are connected to the correct polarity, and that the 2-Amp fuse is installed and not blown.

Understanding Sonar Unit Operation On the Water Unit Operation and the Chart 1 2 3 1 2 3 This fish is currently in a Dead Zone and is not detected by the sonar. The fish is in the coverage area of the transducer, but remember the first strong return sets the bottom level. The fish will eventually be detected when the first strong return sets the bottom level below the fish. If you are familiar with sonar, and can determine what is on the chart, this section may not be for you.
Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. Using Garmin’s standard 20° transducer, the coverage is approximately 1/3rd of the water depth. As shown in Example 1, the coverage area at a 30 foot depth is approximately a 10 foot diameter circle. The scale below illustrates how coverage increases as depth increases.
Understanding the Chart On the Water Understanding the Chart Branches Enlarged Transducer View It is important to understand that the unit does not display a 3-D representation of the underwater environment. The unit can display multiple things at the same time, but can not determine where the return originated only when it was received. Example 2 provides a look at the underwater world from a top view, and relates that view to what would be displayed on the chart.
Whiteline The Fishfinder 100 can help you to determine if the bottom is hard or soft. When the sonar soundwaves are reflected back by the bottom, a hard bottom will return a stronger signal than a soft bottom. The stronger bottom return, the wider the bottom layer is displayed. The unit uses the whiteline function to make this bottom layer information easier to distinguish. When viewing the display without Whiteline active, the bottom return is black.
Thermoclines On the Water Understanding the Chart One of the unique features offered by GARMIN is See-Thru™ technology. See-Thru™ technology allows the Fishfinder 100 to see through thermoclines and helps locate fish where they live, and fish love the thermocline. A rough definition of a thermocline is a break in water where the water temperature changes faster than the water above it. The thermocline usually displays as a gray level as shown below. Thermocline 32 100 On the Water.
Simulator Mode The Fishfinder 100 comes with a built-in simulator mode that will allow the user to practice and learn the operation of the unit at home rather than on the water. To start the simulator mode, turn the unit on without a transducer installed. As the unit powers on, the unit will indicate that it is running the simulator mode by displaying a message across the bottom of the chart. The message will be replaced by the simulator mode icon in the lower left corner of the chart.
