To mount the bracket assembly: 1. Using the swivel base as a template, mark the location of the three mounting holes. 2. If securing the base with machine bolts, drill three 5/32" holes at the locations you marked. If securing the base using selftapping screws, drill 1/16" starter holes at the locations you marked. Generally, starter holes should be no deeper than half the screw length. 3. Secure the swivel base with three bolts or screws. DO NOT OVERTIGHTEN. 4. Attach the swivel bracket and secure it with the short knob. Mounting Holes Swivel Base Short Knob Swivel Bracket and Base 2 Fishfinder 160C Owner's Manual INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION 1. Align the slot on the back of the unit with the long mounting knob and slide into place. It may be necessary to adjust the long knob to spread the bracket arms apart. (Turn counterclockwise to widen the bracket arms, clockwise to tighten.) 2. Adjust the unit angle and tighten the long mounting knob until snug. 3. Tilt the unit by loosening the long knob on the right side of the bracket assembly. 4. Rotate the entire bracket by twisting it left or right. (NOTE: You will hear clicks as you turn the bracket.) 5. Tighten all knobs when the viewing angle you want is obtained. To install the unit on the mounting bracket: Transducer Installation 1. Insert the rubber washer and plastic spacer in the transducer at the same time. DO NOT lubricate the rubber washer. 2. Route the cable toward the back and slide the transducer into the mounting bracket. 3. Place a 5 mm flat washer on the 10-32 x 1.75" screw and insert the screw through the mounting bracket, spacer, and rubber washer. 4. Place the remaining 5 mm flat washer on the exposed end, and install the 10-32 lock nut finger tight. The transducer is tightened further after installation on the boat. To assemble the transducer: Fishfinder 160C Owner's Manual 3 INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION Selecting a Transom Mount Location For your sonar to operate properly, the transducer has to be located in clean (non-turbulent) water. The transducer should be mounted as near the center of the boat as possible. DO NOT cut the transducer lead, this will void your warranty and may degrade the sonar's operation. DO NOT mount the transducer behind strakes, rivet lines, struts, fittings, water intake, discharge ports, eroding paint, or anything that creates air bubbles or causes the water to become turbulent. It is important that the transducer be as close to the center line as possible in calm, non-turbulent water for optimal performance. Avoid mounting the transducer in locations where the boat may be supported during launching, hauling, trailering, or storage. Mount the transducer away from the path of the prop on single drive boats. On twin drive boats, mount the transducer between the drives if possible. Do not mount the transducer directly in the path of the prop. The transducer can cause cavitation that may degrade the boat's performance and damage the prop. Do not mount the transducer behind strakes, rivet lines, struts, fittings, water intakes or discharge ports. Mount the transducer parallel with the water line. Make sure the transducer is below water level when the boat is on plane at high speed. Apply marine sealant to all screw threads to prevent water from seeping into the transom. 4 Fishfinder 160C Owner's Manual INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION Tool List (not included)--drill, 3/8" wrench or socket, 5/32" and 1/8" drill bits, masking tape, #2 Phillips screwdriver, marine sealant. 1. Position the transom mount at the selected location, making sure the transducer is parallel with the water line. Mark the center locations of each hole on the transom mount (see figures to the right). 2. Using the 5/32" bit, drill the pilot holes approximately 1" (25 mm) deep at the marked locations. To avoid drilling the holes too deep wrap a piece of tape around the bit 1" from the point of the bit. 3. Apply marine sealant to the 5 x 30 mm screws. Attach the transducer to the transom using the 5 x 30 mm screws. Adjust the transducer to extend beyond the bottom of the transom approximately 1/8" (3 mm) on fiberglass hulls or 3/8" (10 mm) on aluminum hulls. Adjust the transducer to be aligned parallel with the water. 4. Tighten the 10-32 locking nut until it touches the mounting bracket, and then tighten 1/4 turn more (do not overtighten). Mounting the Transducer on a Transom Drill pilot holes here. Level Vertical Align with transom bottom. Transducer should extend 1/8" below fiberglass hulls or 3/8" below aluminum hulls. Bottom of Transom To mount the transducer on a transom: Keep parallel with water line. OK Fishfinder 160C Owner's Manual 5 INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION Mounting the Transducer on a Trolling Motor 1. Slide the large cable tie through the slot on the transducer mount with the ridges of the band facing up until equal lengths extend on both sides of the mount. (NOTE: For cold water, or heavy timber or debris areas, a metal 4-5" worm gear clamp is recommended.) 2. Position the mount gasket on the curved top of the transducer mount. 3. Place the transducer assembly against the motor body of the trolling motor, with the front of the transducer pointed away from the trolling motor propeller. 4. Wrap the two ends of the cable tie around the motor body. Place the pointed end of the cable tie through the fastener hole on the opposite end and pull it through until it is snug but not tight. (The cable tie clicks when you pull it.) 5. Position the transducer so that it is parallel with the bottom when in use, and make sure the gasket is aligned properly. Pull the cable tie end until tight. Trim off the excess, if necessary. Tighten the 10-32 locking nut until it touches the mounting bracket and then tighten 1/4 turn more. (Do not overtighten.) To mount the transducer on a trolling motor: 6. Route the 30' (9 m) transducer cable using the supplied cable ties to secure the cable to the motor shaft. You can fill the forward-facing portion (except the cable tie pocket) of the transducer mount with sealant to avoid accumulating debris. Cable tie Mounting gasket 6 Fishfinder 160C Owner's Manual INSTALLATION INSTRUCTIONS > TRANSDUCER INSTALLATION Testing the Transom Mount Installation Perform this test after you install the Fishfinder. Because you need water to carry the sonar signal, the Fishfinder does not function properly with the transducer out of the water. When you place your boat in the water, CHECK FOR LEAKS around the screw holes that are below the water line. DO NOT leave your boat in the water for an extended period of time without checking for leaks. 1. Begin testing the installation at a slow speed. If the sonar appears to be working properly, gradually increase the boat's speed observing the sonar's operation. If the sonar signal suddenly is lost or the bottom return is severely degraded, note the speed at which this occurs. 2. Return the boat to the speed at which the signal was lost. Make moderate turns in both directions and see if the signal improves. 3. If the signal strength improves while turning, adjust the transducer so that it extends another 1/8" below the transom of the boat. It might take several adjustments to eliminate the degradation. 4. If the signal does not improve it may be necessary to move the transducer to a different location. To test the transom mount installation: Fishfinder 160C Owner's Manual 7 INSTALLATION INSTRUCTIONS > WIRING HARNESS INSTALLATION Wiring Harness Installation To Transducer (red) + 10-18 VDC The Fishfinder 160C comes with a wiring harness that connects the unit to power and the transducer with one easy-to-remove connection. If it is necessary to extend the power wires, use 22 AWG wire. DO NOT cut the transducer cable, as this will void your warranty. Transducer extension cables are available from your Garmin Dealer. 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 supplied with the unit. You may also wire the unit direct to the battery. To install the wiring harness: 1. 2. 3. 4. Install the Red (+) wire on the positive battery terminal. Install the Black (-) wire on the negative battery terminal. Install a 2 Amp fuse in the fuse holder (fuse block only).

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 cone-shaped pattern. When a transmitted soundwave 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 graph. The underwater data is displayed on the graph in the order that it is returned: first returned--first on the graph. The diagram to the right demonstrates this by showing an underwater scene as it would be displayed on the graph. Generally speaking, if the only thing between the transducer and the bottom is water, the first strong return will come from the bottom directly below the transducer. The first strong return sets the bottom level. Weaker secondary returns provide the detailed data. Sonar returns display as reds (strongest), then oranges (strong), yellows (medium), greens (weaker), and blues (weakest). Fishfinder 160C Owner's Manual That is a brief description of how your Fishfinder 160C operates. The following pages show 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 eventually be detected when the first strong return sets the bottom level below the fish. 21 APPENDIX > TRANSDUCER COVERAGE AND UNDERSTANDING THE GRAPH Transducer Coverage Understanding Transducer Coverage The bottom area covered by the transmitted sound waves is determined by the beam width of the transducer, and the water depth. The Fishfinder 160C can transmit either a Narrow or Wide beam. The Narrow beam provides crisp bottom and structure detail, but the coverage area is limited. As shown in the illustration below, at a 30 foot depth the Narrow beam covers the area of a 6-foot circle. The Wide beam covers a much larger area, but with some loss of bottom and structure detail. As illustrated below, at a 30-foot depth the Wide beam covers the area of a 20-foot circle. 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 where the return originated--only when it 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 graph. On both graphs 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 indicated depths in the same time frame. Understanding the Graph Branches Fish Branches Fish Wide Beam 22 Narrow Beam Example 1 Example 2 Fishfinder 160C Owner's Manual APPENDIX > WHITELINE AND THERMOCLINES Whiteline The Fishfinder 160C 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 returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom while a thick whiteline indicates a harder bottom. Normally, a red line shows the point where water meets the bottom. This line follows the bottom contour, along with any significant objects lying on the bottom. The unit uses the whiteline function to make the bottom layer information easier to distinguish. With the Fishfinder 160C, active whiteline helps accentuate where strong signals are located, which makes bottom type determination easier. The example below shows the bottom return with and without the whiteline activated. Thermoclines Garmin's See-Thru technology allows the Fishfinder 160C to "see" through thermoclines and helps locate fish where they live; and fish love thermoclines! A rough definition of a thermocline is a break in water where the water temperature changes faster than the water above it.
