6 How Your GPS Works You'll navigate faster and easier if you understand how this unit scans the sky to tell you where you are on the earth — and, where you're going. (But if you already have a working understanding of GPS receivers and the GPS navigation system, skip on ahead to Section 2, Installation & Accessories on p ag e 11 .
7 erase 'em and record new ones, over and over again. Like any computer file, these GPS Data Files (file format *.usr) can be shared between other Lowrance GPS or sonar/GPS uni ts and even personal computers. Your unit has one more thing in common with a personal computer.
8 The Global Positioning System (GPS) was launched July 17, 1995 by the United States Department of Defense. It was designed as a 24- hour-a-day, 365-days-a-year, all weather global navigation system for the armed forces of the U.
9 Like most GPS receivers, this unit doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the satellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information.
10 How to use this manual: typographical conventions Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type, so you can easily skim the instructions and pick out what menu command to use.
11 Section 2: Installation & Accessories Preparations You can install the sonar and GPS systems in some other order if you prefer, but we recommend this installation sequence: CAUTION: You should read over this entire installation section before drilling any holes in your vehicle or vessel! 1.
12 Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once the epoxy is applied and it is set into position, the transducer cannot be removed.
13 NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine.
14 How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps.
15 However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction.
16 Align plastic ratchets in bracket. B. Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations.
17 Add ratchets to bracket and transducer. 2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratchets.
18 B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily sl ide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom.
19 B. Two-piece bracket: Once you determine th e correct position for the ratchets, assemble the transducer as shown in the figure in step 2B. Don't tighten the lock nut at this time. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom.
20 Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing th em with the caulking compound.
21 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hopefully, below the turbulence causing the noise.
22 TRANSDUCER ORIENTATION AND FISH ARCHES If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds. Transducer angles and their effects on fish arches.
23 layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area.
24 Shoot-thru-hull transducer locations for high speed or trolling speed operation. To choose the proper location for shoot-thru-hull mounting, follow these testing procedures: (You may need a helper to complete these steps.) 1. Anchor the boat in about 30 feet of water.
25 3. Now move the transducer around to find the best location with the strongest possible bottom signal. If yo u find a spot with an acceptable bottom signal, mark the locati on and move on to step 4.
26 Epoxy transducer to hull. WARNING: Use only the epoxy available from LEI. It has been formulated to work with these installation procedures. Other epoxy types may be too thin or may not cure to the right consistency for optimum transducer performance.
27 Speed/Temperature Sensors Optional Speed Sensor Installation All the units in this series can display speed and distance traveled, but only the LCX-20C comes packed with a speed sensor. If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual.
28 Stern view showing good location for mounting sensor on transom. Speed sensor mounting configuration: side view (left) and rear view (right.) If the base of the transom has a radius, fill the gap between the transom and the sensor with the sealant.
29 signals. The antenna/receiver module comes with a 25-foot Y-adapter extension cable. This module can be mounted on a flat surface or pole, or an optional magnet is available for temporary mounting on any ferrous surface. LGC-2000 Module, bottom view (left) and top view (right).
30 LGC-2000 direct connection to GPS unit. NOTE: The extension cable’s shorter branch will have a 60-ohm terminator attached to it. Do not remove this terminator. When you're not connecting to a NMEA 2000 bus s, you must leave the terminator connected to this socket for your an tenna/receiver to function correctly.
31 LGC-2000 remote connection to NMEA 2000 buss. NOTE: An existing operational NMEA 2000 buss will already have terminators in place and will already be powered. If you're connecting to such a network, you won't need the terminators or extension cable provided.
32 Powering a NMEA 2000 Buss (NMEA 2000 Power cable) A NMEA 2000 buss must be connected to a power source to operate. If you have a pre-existing NMEA 2000 installation, it may already be connected to another power source. If your NMEA 2000 buss is already powered, you can ignore the NMEA 2000 Power cable.
33 power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit. If possible, keep the power cable away from other boat wiring, especially the engine's wires.
34 all electrical devices, this unit could be damaged to a point that it is unrepairable and could even cause harm to the user when not properly fused. CAUTION: Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty.
35 NMEA 0183 Wiring (Data cable) To exchange NMEA 0183 data, this unit has one NMEA 0183 version 2.0 communication port. Com port one (Com-1) can be used to receive NMEA format GPS data. The com port can also transmit NMEA format GPS data to another device.
36 Cable connections. Mounting the Unit: Bracket or In-Dash You can install the unit on top of a dash with the gimbal bracket. It can also be installed in the dash or mounted on a portable power supply.
37 If you use the supplied bracket, you may be interested in the optional R-A-M bracket mounting system. This converts the unit's gimbal bracket to a swivel mount, which can be used on the dash or overhead mounting positions. Optional R-A-M mounting system.
38 Install the gimbal bracket. Place the bracket so the arms slope toward the front of your unit. Once a location is determined, use the bracket as a template and mark the mounting holes and the hole for the cables. Drill a 1-inch (25.4 mm) hole in the dash for the power, transducer and antenna cables.
39 Front view (left) and side view (right) showing dimensions of the sonar/GPS unit when mounted on gimbal bracket. To pass all connectors through the 1" hole, first pass the transducer connector up through the hole from under the dash, followed by the antenna connector and any accessory cables.

43 Section 3: Basic Sonar Operation This section addresses the unit's most basic sonar operations. The instructions presented in Sec. 3 follow a chronological order. Sec. 4, Sonar Options & Other Features , will discuss other more advanced functions and utilities.
44 2. PAGES – Pressing this and the ← → arrow keys switches the unit between the four different page screens. (Satellite Status Page, Navigation Page, Map Page and Sonar Page.) Each page represents one of the unit's major operation modes. 3.
45 Main Menu The unit has a Main Menu, which contains some function commands and some setup option commands. The instructions in this section will deal only with sonar functions, the basic commands that make the unit show sonar signals on your screen.
46 commands. Used to stop navigating after you have reached your destination waypoint, Point of Interest or map cursor location; or after you reach the end of a route or trail. Sonar Setup command: sets various sonar options. GPS Setup command: sets various GPS receiver options.
47 No matter what Page you are on, a flashing current position indicator/question mark symbol and flashing GPS data displays indicate that satellite lock has been lost and there is no position confirmed. WARNING: Do not begin navigating with this unit until the numbers have stopped flashing! Satellite Status Page.
48 always at the top of the screen. The arrow in the center of the screen is your present position. It points in the direction you're traveling. Map Page, showing position on Bull Shoals Lake, Arkansas. The full map option (left). Map with sonar option (right).

50 Sonar Page Menu. Most of these functions are discussed in Sec. 4. Sonar Page, showing full sonar chart mode. You can customize how the Sonar Page displays its pictures and other data in many ways. Your unit also includes several special sonar features and options that can help you better interpret the underwater scene.
51 LCX-20C Sonar Quick Reference 1. Mount the transducer, antenna and unit. Connect the unit to electric power and the transducer. (If GPS operation is desired, connect GPS antenna, too.) Make sure the MMC is in. (See complete installation details beginning on page 11.
52 Sonar Operations As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for how it's working.
53 Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on. You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting.
54 Important Tip: While you are experimenting and learning, it's possible to scramble the settings so that the sonar picture disappears from your screen. If that happens, remember that it's easy to switch back to full automatic operation by simply restoring the factory auto settings.
55 Visit our web site, www.lowrance.com . Be sure to check out the free Sonar Tutorial, which includes animated illustrations and more pictures of actual sonar returns, all described in detail.
56 A free training emulator is available for your unit on our web site. The emulator works exactly like your real sonar/GPS unit. Using the Sonar Simulator and GPS Simulator features, it allows you to.
57 Section 4: Sonar Options & Other Features Material in this section is arranged in alphabetical order. ASP (Advanced Signal Processing) The ASP feature is a noise rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions and interference.
58 Alarms This unit has three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines an echo is a fish. Another alarm is the Zone Alarm, which consists of a bar on the side of the screen. Any echo on the chart that appears inside this bar triggers the alarm.
59 4. Press ← to S HALLOW A LARM E NABLED | ENT | EXIT | EXIT | EXIT . 5. To turn off the alarm, press MENU | MENU | ↓ to A LARMS | ENT | ↓ to S ONAR A LARMS | ENT | ENT | EXIT | EXIT | EXIT . To switch to a different depth setting, open the Sonar Alarms menu and repeat the instructions in step 3 above.
60 4. To set the lower boundary for the Zone Alarm, use ← or → to select L OWER , then press ↑ or ↓ to move the bottom of the bar to the desired depth. 5. Press EXIT | ← to Z ONE A LARM E NABLED | ENT | EXIT | EXIT | EXIT . Now, any echo — fish, bottom, structure — within the zone alarm's depth range will trigger the zone alarm.
61 actual speed, you will enter – 10 in the calibration window. If the sensor is reading 5 percent slower than true speed, you will enter + 5 in the window. A good way to gauge your speed sensor's performance is to compare its reading with the ground speed measured by your unit's GPS functions.
62 If you do experiment with chart speed, remember to reset it to maximum when you resume trolling or moving across the water at higher speed. To change chart speed: 1. From the Sonar Page, press MENU | ↓ to C HART S PEED | ENT . 2. The Chart Speed Control Bar appears.
63 The "A" figures to the left show locations with ColorLine set at the factory level of 70 percent. The "B" figures on the right show the same locations with ColorLine increased to 84 percent. In Figure 1B, no fish are near the left structure, but t he right structure shows fish holding next to the structure.
64 Sonar Page menu with Depth Cursor command selected (left). Sonar chart with the depth cursor active (right). The line indicates the large fish is 21.95 feet deep. The cursor can be moved to any location on the screen, letting you pinpoint the depth of a target.
65 2. The Depth Range Control Scale appears. Press ↑ or ↓ t o s e l e c t a different depth range. A blue bar highlights the selected range. The lighter range numbers can not be selected. 3. When the new range is selected, press EXIT to clear the menu.

From the Sonar Page, press MENU| ↓ to U PPER A ND L OWER L IMITS | ENT . The Sonar Chart Limits menu appears, with Upper Limit selected.
67 conditions directly under the boat. This makes it useful for ice fishing, or when you're fishing at anchor. When the boat is not moving, fish signals are long, drawn out lines on a normal chart display. FasTrack converts the graph to a vertical bar graph that, with practice, makes a useful addition to fishing at a stationary location.
68 The Sonar Features menu. To turn the Fish I.D. feature on: 1. From the Sonar Page, press MENU | ↓ to S ONAR F EATURES | ENT . 2. Press → to F ISH S YMBOLS | ENT | EXIT | EXIT . To turn off Fish I.D., repeat the instructions in step 1. Figures 1A and 2A (left) show Sonar Page in normal chart mode.
69 FishTrack The FishTrack feature shows the depth of a fish symbol when it appears on the display. This lets you accurately gauge the depth of targets. This feature is available only when the Fish I.D. feature is on. The default setting for FishTrack is off.
70 There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch the bait.
71 The Sonar Page menu with the Log Sonar Chart Data command selected (left). Sonar Chart Logging menu, with the Start Logging command selected (right). The MMC has 11.7 MB of free space, which will record the scrolling chart for 20 minutes and 44 seconds.

81 Split Zoom Sonar Chart A split chart shows the underwater world from the surface to the bottom on the right side of the screen. The left side shows an enlarged version of the right side. The zoom range shows at the bottom left corner of the screen.
82 3. The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity; press ↑ to increase sensitivity. When it's set at the desired level, press EXIT . (When you reach the maximum or minimum limit, a tone sounds.) The Split Frequency Sonar Chart page allows you to adjust sensitivity separately for each window.
83 Trip Calculator, Time, Sonar and Miscellaneous Data You can select items from any of these categories for display in any data box. The category divisions are only there to help you sort through the information.
84 show weaker targets as lighter colors. The bottom depth is shown as a black bar across the outer circle. You can adjust the size of the chart and the flasher windows by using the Resize Window command, which is described on page 105. FlashGraf page.
85 Sonar Simulator This unit has a built-in simulator that lets you run it as if you were on the water. All sonar features and functions are useable. When in simulator mode, you will see the chart file name in the Sonar Page title bar and a play symbol will flash on and off at the right end of the title bar.
86 Tip: The Sonar Simulator can use sonar charts recorded (logged) on a MMC card. (To see how, read the entry in this section on Log Sonar Chart Data.) To play back a sonar chart, make sure the MMC containing the chart is installed, then: 1. Press MENU | MENU | ↓ to S ONAR S ETUP | ENT | ↓ to S ONAR S IMULATOR | ENT .
87 Sonar Menu with Stop Chart command selected. The box is unchecked, indicating the chart is scrolling across the screen. Surface Clarity The markings extending downward from the zero line on the chart are called "surface clutter." These markings are caused by wave action, boat wakes, temperature inversion and more.
88 In the illustration on the left, Surface Clarity is turned off. The view on the right shows Surface Clarity set on high. Transparency Use the transparency menu to adjust the transparency of menu windows.
89 Zoom & Zoom Bar "Zooming in" is a common, fast and easy method used to enlarge small detail, fish signals and the bottom with its associated structure. This unit lets you zoom in quickly and easily by pressing the Zoom In key, ZIN . Pressing ZIN once doubles the size (2X) of all echoes on the screen.
90 Notes.
91 Section 5: Sonar Troubleshooting If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit for repair.
92 This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar's ability to find the bottom.
93 NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonar's display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit to operate erratically, or not at all.
94 Notes.
