Getting Started Getting Started To get the most out of your new Fishfinder: • Before you install and use your Fishfinder, read the information in this manual. • Assemble and install the hardware (page 5). • Practice using your Fishfinder in Simulator Mode (page 4). • Use the Fishfinder (page 14).
Getting Started wave information, and then sends the information to the Fishfinder. The Fishfinder displays the information on the screen for you to see and interpret. The type of transducer and settings you choose determine how the information is shown on the screen. Understanding Dual Beam Transducer Coverage A dual beam transducer can transmit a narrow or a wide beam. The water area covered by the transmitted sound waves is determined by the beam width of the transducer and the water depth.
Getting Started Understanding the Fishfinder Screen Experimentation and experience are the keys to successfully interpreting your Fishfinder screen. We recommend that you take your Fishfinder out on familiar water, and spend time learning to interpret what you see on the Fishfinder 90 or 140 screen. Think of the Fishfinder screen as if you took a picture from the side of an aquarium in your home.
Getting Started The Fishfinder 90 and 140 include the latest technology in interpreting bottom signals; they can see through fish, structures, and thermoclines (shown in the weakest hues). Even so, large schools of fish or dense structures close to the bottom can affect water depth return readings. NOTE: If the Fishfinder is unable to track the bottom for any reason, the digits which indicate depth flash on and off to alert you that the Fishfinder is not tracking the bottom.
Installing Your Fishfinder Installing Your Fishfinder Make sure you completely read and understand all instructions before you install and use your Fishfinder. If you have problems, contact Garmin Product Support, or seek other professional assistance. You can install the Fishfinder hardware on a transom or on a trolling motor. Before installation, make sure the wiring harness can reach the Fishfinder and transducer locations.
Installing Your Fishfinder Installing the Transducer Assembling the Transducer 1. Insert the rubber washer (Q) and plastic spacer (P) into the transducer (G) at the same time. DO NOT lubricate the rubber washer. 2. Route the cable toward the back of the transducer. Slide the transducer into the transducer mount (H). 3. Place a 5 mm flat washer (J) on the 10-32 x 1.75" screw (N), and insert the screw through the transducer mount, spacer, and rubber washer. 4.
Installing Your Fishfinder 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.
Installing Your Fishfinder • DO NOT mount the transducer in the path of the prop on single-drive boats. The transducer can cause cavitation that can degrade the boat’s performance and damage the prop. On twin-drive boats, mount the transducer between the drives, if possible. Do not mount the transducer behind strakes, rivet lines, struts, fittings, water intakes or discharge ports. Mount the transducer parallel with the water line.
Installing Your Fishfinder To mount the transducer on a transom: 1. Position the transducer mount at the selected transom location. Make sure the transducer is parallel with the water line. Mark the center locations of each hole on the transducer mount. (See the figures on the next page.) 2. Using a 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 at 1" from the point of the bit. 3.
Installing Your Fishfinder Installing the Fishfinder Unit Drill pilot holes here. Selecting a Fishfinder installation Location Align with the transom bottom. The transducer should extend 1/8" below fiberglass hulls or 3/8" below aluminum hulls. Vertical Level Bottom of Keep it parallel with the water line. OK 10 190-00582-10_0A.indd 10 m the transo Select a Fishfinder installation location that allows you to view and operate it easily while operating the vessel.
Installing Your Fishfinder To mount the bracket assembly: 1. Using the tilt mount bracket (Fishfinder 90) or the swivel base (Fishfinder 140; Fishfinder 90 option) as a template, mark the location of the three holes that you use to secure the bracket to the mounting surface. 2. If securing the base with machine bolts, drill three 5/32" holes at the locations you marked; or, if securing the base using self-tapping screws, drill 1/16" starter holes at the locations you marked.
Installing Your Fishfinder Installing the Wiring Harness The Fishfinder comes with a wiring harness that connects the Fishfinder 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, because this voids your warranty. If your boat has an electrical system, you might be able to wire the Fishfinder directly to an unused holder on your current fuse block.
Installing Your Fishfinder 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. Fishfinder 90/140 Owner’s Manual 190-00582-10_0A.
Operating Your Fishfinder Operating Your Fishfinder Arrow keys—the up and down Arrow keys select an item on a menu. Only the Fishfinder 140 has the right and left Arrow key that cycles through the Main menu options. ENTER key—confirms a selection. ENTER MENU MENU key—shows or exits a menu. Understanding Basic Functions To turn on the Fishfinder: Press and release the Power key. To turn off the Fishfinder: Press and hold the Power key.
Operating Your Fishfinder 3. To select a setting, use the Arrow keys to move the selection arrow, and press ENTER. (When you reach the end of a menu, the selection arrow wraps to the beginning.) Press and hold an Arrow key to rapidly advance the selection speed. 4. To close a setting or a menu, press MENU. • To quickly change a setting for the current option that appears in the upper-left corner of the screen (for example, the Range option in the above screen), press an Arrow key.
Operating Your Fishfinder Scroll—sets the rate that the graph scrolls from right to left. If you are sitting still or the graph is moving too fast, slowing or pausing the graph can help. The settings are Ultra, Fast (default), Medium, Slow, and Paused. Using the Setup Menu Zoom—sets the zoom level for the screen. Off is the default. Options and Settings View—when you select a 2X or 4X Zoom setting, you can select a specific area to view on the screen.
Operating Your Fishfinder Graphs Fish ID—sets how the Fishfinder shows underwater targets and background information. If you select a fish symbol, the screen shows only the information related to that symbol (large, medium, and small sizes). When using wide beam, fish symbols that are to the sides of the boat appear hollow. Those that are directly below the boat appear as solid black fish symbols. (default) the Fishfinder does not interpret the sonar return data.
Operating Your Fishfinder Auto Gain—controls the aggressiveness of the Auto Gain. The higher the setting, the greater the number of targets appear on the screen. The lower the setting, the less clutter on the screen. The settings are High, Medium (default), and Low. Numbers Size—sets the appearance of depth, temperature, and battery numbers. The settings are Small and Large (default). Battery—sets whether the current battery voltage appears on the screen.
