Fishfinder 160 Blue Display? The Fishfinder 160 Blue is capable of displaying a variety of useful information about the underwater environment. Below are a few things the unit will help you see. Water Depth 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 or temperature sensor, the unit can display the water temperature. Speed Over Water* If equipped with a capable transducer or speed sensor, the unit can display the boat's speed over water. Fish The unit displays fish as arches or fish symbols, and can alert you when a fish is detected. Thermocline and Structure With GARMIN's See-Thru® technology, the Fishfinder 160 Blue can display more than just the thermocline and structure. The unit displays fish in and below the thermocline, trees, brush and deadfall like you have never seen before! Bottom Shape and Type The screen shots shown in this manual are simulated. Images seen during actual operation will be influenced by environmental conditions, and may differ from the images shown here. Garmin's unique DCG® (Depth Control Gain) system provides a clear graphic representation of the bottom type and its shape. Transducer Frequency* If equipped with a capable transducer, the unit will display the frequency selected for use; either 200kHz, 50kHz or Dual. vi * Requires optional transducer or speed sensor 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. Included in the Optional Package is a 200/50kHz frequency (10°/40° cone angle), depth and temperature sensing, transom mount transducer. This transducer provides good all-around performance. Other optional dual frequency transducers are available from your local dealer or GARMIN. The transducer transmits sound waves toward the bottom in a cone shape. The wider 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 frequency setting that suits the water that you are on. With a dual frequency transducer, you may select either a 200kHz frequency, a 50kHz frequency or both. The 50kHz frequency setting provides a wide cone angle. This wide cone angle produces a large coverage area, but less detailed bottom resolution. In areas where bottom contours change quickly, this can result in "dead zones" where fish cannot be seen. In contrast, the 200kHz frequency setting provides a narrow cone angle. This narrow cone angle produces a smaller viewing area (compared to a wide cone angle at the same depth), but with improved bottom resolution and a smaller dead zone. The Dual frequency setting will provide you the most accurate depth and fish returns by transmitting signals at both 200kHz and 50kHz. Installation Transducers 50 kHz wide cone angle narrow cone angle 200 kHz dead zone fish not seen X X 1 Installation Mounting the Transducer 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 or any part of the transducer cable, as this will void your warranty. The cable cannot be spliced and connected to any existing (GARMIN or nonGARMIN) transducer cables. Following are some tips and basic installation instructions for the optional dual frequency transducer and speed sensor. Detailed installation instructions are provided in the transducer kits. Transom Mount Installation DO NOT mount the transducer behind strakes, struts, fittings, water intake or discharge ports, or anything that creates air bubbles or causes the water to become turbulent. It is important that the transducer be in calm, non-turbulent water for optimal performance. Dual Frequency Transom Mount Transducer (with depth/temp). NOTICE: Both the Transom Mount Transducer and the Speed Sensor must be installed separately. These two sensors may not be combined. Apply marine sealant to all screw threads to prevent water from seeping into the transom. Transducer should extend 1/8" below fiberglass hull or 3/8" below aluminum hull Mount the transducer cable cover well above the waterline. Make sure that the transducer is below water level when the boat is on plane at high speed OK Do not mount transducer directly in the path of the prop. The transducer can cause cavitation that may degrade the boat's performance and damage the prop. Mount the transducer parallel with the bottom. 2 In-Hull Installation To avoid drilling a hole to mount a thru-hull transducer, a transom mount transducer may be used with epoxy inside a boat (also called "shootthru-hull" installation). For a transducer to be mounted inside the hull (shoot-thru, not thru-hull), the boat must be fiberglass, no core (contact your boat manufacturer if you are unsure). Test by placing a small amount of water inside the hull, placing the transducer on top of the water, then verifying the accuracy of the locators versus the current water depth. If they are the same, use epoxy (non-silicone based) to affix the transducer to the inside of the hull. If using a temperature sensing transducer, the temperature displayed will reflect the hull temperature. Selecting a Location The location has to be solid fiberglass, devoid of any air bubbles, laminates, fillers or dead air space. The location needs to be in an area of clean water at all speeds. Do not place the transducer over any strakes or behind any obstruction on the hull that would create turbulence. Installation Mounting the Transducer Many modern hulls have a pre-located pocket for In-hull transducer installation. If you are unsure if your hull is equipped with a prelocated pocket, contact your hull manufacturer. Testing the Location Place the transducer in the water, pointed directly at the bottom, and set the unit for optimum performance. Place the transducer in the test device as show on the side bar. If the sonar performance is significantly degraded, another location will need to be tested. Weight transducer to hold it in place PVC Pipe or a Can Fill Pipe or Can with water or a light mineral oil Strip Caulk or RTV Sealer Hull Surface Testing the Location Continued on page 4 3 In-Hull Installation (continued) Installing the Transducer: Installation Mounting the Transducer/ Speed Sensor Apply twisting motion to eliminate any trapped air bubbles Weight transducer in place for at least 24 hours Slow cure 2-part epoxy 1. Lightly sand the surface of the hull and face of the transducer with 400 grit wet or dry sandpaper. 2. Build a dam using strip caulk about 1/4" tall. Pour about 1/8" of 2-part, slow cure epoxy in the dam. Place the transducer in the epoxy, turning the transducer to work out any air bubbles. 3. Weight the transducer in place and allow to cure for 24 hours. Speed Sensor Installation Strip Caulk or RTV Sealer The speed sensor should be mounted as near the center of the boat as possible. Like the transducer, for the speed sensor to operate properly, it should be located in non-turbulent water. Follow the directions in the speed sensor installation instructions to assemble the speed sensor with the mounting bracket, drill holes in the transom, mount the assembly and route the cable. Installing the Transducer Drill a 3/4" hole well above the water line. Coat the inside of the hole with Marine Sealant. OK Position Cable Clamps about one-third of the distance from the hole to the transducer. Adjust the speed sensor so it is parallel with the bottom of the boat. If the speed sensor is not adjusted properly, the sonar may experience inaccurate or degraded speed readings. Drill 1/8" pilot holes 3/8" deep for the mounting screws. Coat the screws with Marine Sealant before installing them. 4 Wiring Harness Installation The Fishfinder 160 Blue 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. Transducer extension cables are available in 10' or 20' lengths from your GARMIN dealer. Wiring to a Fuse Block Installation Installing the Wiring Harness 10-18 Volt Boat Supply + Install 2-Amp Fuse If your boat has an electrical system, it may be possible to wire the unit directly to an unused holder on your current fuse block. If you are using the boat's fuse block, remove the in-line fuse holder supplied with the unit. Installing the Wiring Harness: 1. Determine the polarity of the fuse holder using a Test Light or Volt Meter. 2. Install the Red (+) wire on the Positive Fuse Holder Terminal. 3. Install the Black (-) wire on the Negative Fuse Holder Terminal. 4. Install a 2 amp fuse in the Fuse Holder. Boat Ground Black Wire 2A During a typical installation, only the Red and Black wires are used. The Blue wire supplies NMEA data, and doesn't have to be connected for normal operation of the unit. The Yellow (alarm) wire is not used, because the Fishfinder 160 Blue does not support external alarms. Continued on page 6 Fishfinder 160 Blue Red Wire 5 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 160 Blue can be connected to another piece of NMEAcompatible electronic equipment. If equipped with a capable transducer and speed sensor, the Fishfinder 160 Blue sends depth, temperature and speed information that could be displayed on another device. Power/Data er/Data Connection (BLUE) NMEA Out (RED) +10 to +15 VDC 2-Amp In-Line Fuse (BLACK) Ground TRANSDUCER CONNECTION Speed Temp Transducer Connecting a Transducer to Multiple Sensors NMEA Device Power Source 6 Display Installation (Surface Mount) The Fishfinder 160 Blue can be mounted to a flat surface using the supplied Surface Mount Bracket. Surface Mounting the Display: 1. Position the Surface Mount Bracket 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 Bracket using the mounting fasteners. 5. Slip the unit into the Surface Mount Bracket. 6. Tighten the knobs to secure the unit to the bracket. Installation Installing the Display Mounting Bracket The Surface Mount Bracket is designed to be secured using a flat head screw. If you use a screw with a countersunk head, you risk damaging the Surface Mount Bracket. Surface Mount Bracket OK 7 Display Installation (Flush Mount) Installation Installing the Display The Fishfinder 160 Blue can be mounted flush against a dash or electronics rack that is no more than 1/4" thick. Flush Mounting the Display: 1. Remove the Mounting Bracket from the back of the unit by removing its four screws. 2 Using the Mounting Bracket as a template, mark the location of the four mounting holes and the center relief hole. 3. Drill the mounting holes using a 6mm or 15/64" drill. 4. Using a 1-7/8" hole saw, cut the center relief. Be careful not to install screws that are too long! The mounting holes in the unit are approximately 1/4" deep. Installing screws that are too long will damage the unit and void the warranty. 5. Secure the unit to the mounting surface using four M5 screws. If you are flush mounting the unit on a sheet metal surface, use the mounting bracket on the back to help reinforce the metal. You may also purchase the optional Flush Mounting Kit and follow the flush mounting instructions included with the kit. Mounting Bracket 8 Testing the Installation While it is possible to perform some checks with the boat trailered, the boat should be in the water to properly test the installation. Press the POWER button and the Fishfinder 160 Blue 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 the 2-Amp fuse is installed and not blown. If the unit is connected to a power supply that exceeds 18 VDC, a `Battery Voltage High' warning will be displayed and the unit will turn off. As the unit powers on, it should immediately start showing the bottom. Verify that the unit is not in the simulator mode. If the unit is in the simulator mode, make sure that the transducer is connected to the wiring harness. Installation Testing the Installation Simulator Message and Icon To test the transducer and speed sensor installation, gradually increase the boat's speed while checking the unit operation. If the unit displays intermittently or fails to display, verify that the transducer and speed sensor are aligned parallel with the bottom. If necessary, adjust their heights until the unit operates correctly. It may be necessary to make several adjustments to ensure proper operation throughout the speed range. If the signals do not improve, it may be necessary to move the transducer or speed sensor to a different location. If the Fishfinder 160 Blue is in Simulator Mode, the message "Simulator On" will be displayed along the bottom of the screen. The message will be replaced by the "S" icon indicating that the unit is running in simulator mode. When adjusting the depth of the transducer, make the adjustments in small increments, like 1/8". Placing the transducer or speed sensor too deep can adversely affect the boat's performance and increase the risk that they may strike underwater objects. 9 Unit Operation Keypad Functions Arrow Keys The ARROW keys are used to select items on the Adjustment Bar and Setup Menu and to change field data.

Unit Operation Setup Menu: Chart Tab Chart Tab The `Chart' tab allows the user to determine the appearance of the scrolling chart display. To access the `Chart' tab, place the highlight over it using the arrow keys. Frequency The `Frequency' setting allows you to choose a transducer frequency. Frequency refers to the "pitch" of the sound that the transducer sends and receives. You may choose `200kHz' (default), `50kHz' or `Dual' frequency. Frequency Settings Continued on page 16 15 Frequency (continued) Unit Operation Setup Menu: Chart Tab The wide cone angles associated with low frequencies (40° for 50kHz) provide a large coverage area for finding fish. However, this also means that wide cone angles produce less bottom detail and resolution. The narrow cone angles associated with high frequencies (10° for 200kHz) provide better bottom resolution and crisper detail, but therefore cannot show a large coverage area for finding fish. Dual frequency mode combines the improved contour detail and depth readings of the 200kHz frequency with the wide coverage area of the 50kHz frequency. To select a Frequency: 1. Highlight the `Chart' tab on the Setup Menu. 2. Highlight the `Frequency' selection field and press ENTER. 3. Using the UP or DOWN Arrow, choose `200kHz,' 50kHz' or `Dual' and press ENTER. The selected frequency will be displayed in the bottom left-hand corner of the chart. Fish Symbols -- Arches wil be displayed representing suspended targets. Fish Symbols All available backgroud information will be displayed. -- Suspended targets displayed as symbols. In this mode, background information will still be displayed making fish identification easier. -- Same as above, with target depth displayed. `Fish Symbols' allows the user to determine how the chart will display underwater targets and background information. If `Fish Symbols' is set to `Off,' the unit will display all of the available information about the underwater environment. If a fish symbol is selected, the chart will display only the information related to that symbol. To select a Fish Symbol: 1. Highlight the `Chart' tab on the Setup Menu. 2. Highlight the `Fish Symbols' selection field and press ENTER. 3. Using the UP or DOWN Arrow, select the desired symbol and press ENTER. -- Suspended targets displayed as symbols.

Software Version Information 29 On the Water Unit Operation and the Chart Understanding Sonar If you are unfamiliar with sonar, or need help determining what is displayed on the chart, then this section may be for you. This section is intended to help the novice user gain some understanding of how the Fishfinder 160 Blue operates and how it can help improve their fishing productivity. To understand what the unit is displaying, it is important to have a general knowledge of how the unit works and how it determines what to display. Briefly described, the unit operates by transmitting sound waves toward the bottom of a lake, stream or seabed in a cone­shaped pattern. When a transmitted sound wave strikes an underwater object such as the bottom, a piece of structure, or a fish, sound is reflected back to the transducer. The transducer collects the reflected sound waves and sends the data to the unit to be processed and displayed on the chart. Underwater data is displayed on the chart in the order that the reflected sound waves are received. The diagram in the sidebar demonstrates this, showing an underwater scene as it would be displayed on the chart. Generally speaking, if the only thing between the transducer and a flat bottom is water, the first strong return will come from the bottom directly below the transducer, this return will set the bottom level. Weaker secondary returns provide the detailed data. Stronger returns will display in darker colors, with black being the strongest return. In Examples 1 and 2 (page 32), you can see that the branches and the fish were the strongest secondary returns and are indicated in black on the display. That is a brief description of how your Fishfinder operates. Let's take a look at how this data can help you to improve your fishing. 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 never be detected since the bottom level will never be set below the fish. The fish on the right side of the display (shown in light grey) will be detected and displayed when the transducer cone passes over the fish. 30 Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. The 50kHz frequency provides a 40° cone angle, with a coverage width that is approximately 2/3 of the water depth. As shown in the sidebar, the 40° cone angle (50kHz frequency) approximately covers the area of a 20 foot diameter circle at a 30 foot depth. The 200kHz frequency provides a 10° cone angle, with a coverage width that is approximately 2/10 of the water depth. As shown, the 10° cone angle (200kHz frequency) approximately covers the area of a 6 foot diameter circle at a 30 foot depth. When using the Fishfinder 160 Blue in `Dual' frequency mode, the unit transmits both 50kHz and 200kHz signals at the same time. The `Dual' frequency capability of the Fishfinder 160 Blue allows the user to have a large coverage area and still retain good bottom resolution. When in `Dual' frequency mode the unit uses the 200kHz to display detailed bottom information, keeping "Dead Zones" to a minimum, and the 50kHz signal for the large coverage area. Fish returns from the 50kHz and 200kHz beams will appear differently on the display. The 50kHz beam tends to show longer fish returns than the 200kHz beam. The examples below show simulated fish returns at 50 and 200 kHz. On the Water Transducer Coverage 200kHz - 10° Cone Angle 72" coverage at 30' 50kHz - 40° Cone Angle 20' coverage at 30' 50kHz 200kHz 31 Understanding the Chart On the Water Understanding the Chart 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 cannot determine from where the return originated. It can only determine when the return was received. Examples 1 and 2 provide a look at the underwater world from a top view, and illustrate how these views would be displayed on the chart. On both charts it appears the fish and tree are side by side as shown in Example 1. However, when we look at Example 2, we see that the fish can be several feet from the tree. It is important to remember that the Fishfinder cannot determine where in the coverage area the tree or fish are, only that the returns were received at the indcated depths in the same time frame. Remember that the Fishfinder displays a 2-D picture of the underwater environment. The fish and tree could be located anywhere in the coverage area produced by the sonar cone at the object's indicated depth. Branches Enlarged Transducer View Enlarged Transducer View Branches Fish Fish 32 Example 1. Example 2. Whiteline The Fishfinder 160 Blue 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 the 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. While you can make some determination of the bottom type, the black return makes this more difficult. With the Whiteline active, the bottom return appears layered in shades of gray and black, which makes determining the bottom type easier and more reliable. Example 3 shows the bottom return with and without the Whiteline activated. On the Water Understanding the Chart Whiteline can also help you to determine the type of bottom structure that is displayed on the chart. By determining the hardness of the structure you can make a better informed decision as to the type of structure. Hard Bottom Soft Bottom Whiteline Turned Off Whiteline Whiteline Activated Structure is hard, probably a rock or stump Structure is soft, probably a mud pile Example 3. 33 Thermoclines On the Water Understanding the Chart
