navigation, look over this segment describing how GPS and its new companion WAAS work together to get you where you're going. The United States Department of Defense launched Global Positioning System (GPS) on July 17, 1995. 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.S. and its allies. Civilian use was also available, but it was less accurate because the military scrambled the signal somewhat, using a process called Selective Availability (SA). GPS proved so useful for civilian navigation that the federal government discontinued SA on May 2, 2000, after the military developed other methods to deny GPS service to enemy forces. Reliable accuracy for civilian users jumped from 100 meters (330 feet) under SA to the present level of 10 to 20 meters (about 30 to 60 feet.). Twenty-four satellites orbit 10,900 nautical miles above the Earth, passing overhead twice daily. A series of ground stations (with precisely surveyed locations) controls the satellites and monitors their exact locations in the sky. Each satellite broadcasts a low-power signal that identifies the satellite and its position above the earth. Three of these satellites are spares, unused until needed. The rest virtually guarantee at least four satellites are in view nearly anywhere on Earth at all times.
A minimum of three satellites are required to determine a 2D fix.
The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level also called altitude). This is called a 3D fix. Remember, the unit must have a clear view of the satellites in order to receive their signals. Unlike radio or television signals, GPS works at very high frequencies. Trees, buildings, an automobile roof, even your body can easily block these signals.
Like most GPS receivers, this unit doesnt 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. Therefore, in order for the unit to determine direction of travel, you must be moving and the faster, the better. This is not to say that it wont work at walking or trolling speeds it will. There will simply be more "wandering" of the data shown on the display. GPS is accurate enough for route navigation, but the U.S. Federal Aviation Administration has special needs for aircraft traffic control that go beyond basic GPS. The FAA has a program to boost GPS performance even further with its Wide Area Augmentation System, or WAAS. This GPS add-on will include a time control element that will help airliners fly closer together while avoiding collisions. In addition to carefully spacing airplanes along travel corridors, WAAS will eventually make instrument landings and takeoffs more accurate as it replaces existing aviation navigation systems. Non-aviators can use WAAS signals to make their GPS navigation even more accurate. Your unit receives both GPS and WAAS signals. WAAS, however, has some limits you should know about. WAAS can boost the accuracy of land GPS navigation, but the system is designed for aircraft. The satellites are in a fixed orbit around the Equator, so they appear very low in the sky to someone on the ground in North America. Aircraft and vessels on open water can get consistently good WAAS reception, but terrain, foliage or even large man-made structures frequently block the WAAS signal from ground receivers. You'll find that using your GPS receiver is both easy and amazingly accurate. Its easily the most accurate method of electronic navigation available to the public today. But remember this receiver is only a tool. Always have another method of navigation available, such as a map or chart and a compass. Also remember this unit will always show navigation information in the shortest line from your present position to a waypoint, regardless of terrain! It only calculates position; it cant know whats between you and your destination. Its up to you to navigate safely around obstacles, no matter how youre using this product.

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. Determine the approximate location for the sonar/GPS unit, so you can plan how and where to route the cables for the antenna, transducer and power. This will help you make sure you have enough cable length for the desired configuration. 2. Determine the approximate location for the transducer and its cable route. 3. Determine the approximate location for the GPS antenna module and its cable route. 4. Determine the location of your battery or other power connection, along with the power cable route. 5. Install the transducer and route the transducer cable to the sonar/GPS unit. 6. Install the GPS antenna and route the antenna cable to the sonar/GPS unit. 7. Install the power cable and route it to the sonar/GPS unit. 8. Mount the sonar/GPS unit.

Transducer Installation

These instructions will help you install your Skimmer transducer on a transom, on a trolling motor or inside a hull. These instructions cover both single- and dual-frequency Skimmer transducers. Please read all instructions before proceeding with any installation. The smaller single-frequency Skimmers typically use a one-piece, stainless steel mounting bracket. The larger dual-frequency Skimmers typically use a two-piece, plastic mounting bracket. The trolling motor mount uses a one-piece plastic bracket with an adjustable strap. These are all "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools. 9
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. Remember, the transducer installation is the most critical part of a sonar installation. Recommended Tools and supplies If you prefer the option of routing the cable through the transom, you will need a 1" drill bit. A transom mount requires use of a high quality, marine grade above- or below-waterline caulking compound. NOTE: The following installation types also call for these recommended tools and required supplies (supplies are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flathead screwdriver. Supplies: high quality, marine grade above- or belowwaterline sealant/adhesive compound.
Dual-frequency transom installations

CAUTION: Clamp the transducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location
Poor location Good location Good location Poor angle Good and poor transducer locations.
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.
Transducer centerline Transom
Hull bottom Align transducer centerline with hull bottom.
However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross-wave or wake. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. If you wish, you may move the transducer a little higher for more protection. There are two extremes you should avoid. Never let the edge of the mounting bracket extend below the bottom of the hull. Never let the bottom the face of the transducer rise above the bottom of the hull. Shoot-thru-hull vs. Transom Mounting In a shoot-thru-hull installation, the transducer is bonded to the inside of the hull with epoxy. The sonar "ping" signal actually passes through the hull and into the water. This differs from a bolt-thru-hull installation (often called simply "thru-hull"). In that case, a hole is cut in the hull and a specially designed transducer is mounted through the hull with a threaded shaft and nut. This puts the transducer in direct contact with the water. Typically, shoot-thru-hull installations give excellent high-speed operation and good to excellent depth capability. There is no possibility of transducer damage from floating objects, as there is with a transommounted transducer. A transducer mounted inside the hull can't be knocked off when docking or loading on a trailer. 12

Spread epoxy here

Sand this surface (unit's face) Orient the Skimmer with the nose facing the bow of the boat. To bow
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. 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the package and place them on the paper plate. Thoroughly stir the two compounds together until the mixture has a uniform color and consistency. Do not mix too fast or bubbles will form in the epoxy. After mixing, you have 20 minutes to complete the installation before the epoxy becomes unworkable. Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of the transducer as shown in the previous figure. Make sure there are no air pockets in the epoxy layer! Then, apply the remaining epoxy to the sanded area on the hull. 3. Press the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. Stop pressing when you bottom out on the hull. When you're finished, the face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. 4. Apply a weight, such as a brick, to hold the transducer in place while the epoxy cures. Be careful not to bump the transducer while the epoxy is wet. Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat. 5. After the epoxy has cured, route the cable to the sonar unit and it's ready to use. 24
Speed/Temperature Sensors
Optional Speed Sensor Installation If you wish to purchase an optional or additional speed sensor for your unit, visit our website, www.lowrance.com, or refer to the accessory ordering information inside the back cover of this manual. The following instructions describe how to install the speed sensor. Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit for pilot holes, screwdriver. Required supplies for this job include: four #8 stainless steel wood screws (3/4" long), high quality, marine grade above- or below-waterline sealant. First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane. Also make sure the location doesn't interfere with the boat's trailer. Typically, the sensor is mounted about one foot to the side of the transom's centerline. Once you've determined the proper location for the unit, place the sensor on the transom. The bottom of the bracket should be flush with the hull's bottom. Using the sensor as a template, mark the hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of the slots. Mount the sensor to the hull using #8 stainless steel wood screws (not included). Use a high quality, marine grade above- or below-waterline sealant to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.

Good location Stern view showing good location for mounting sensor on transom.

Transom

Bottom of hull 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. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 7/8". CAUTION: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the screws. The sensor is now ready for use. Connect the sensor to the sonar socket on the back of your unit and connect the transducer to the speed sensor's socket. If you have any questions concerning the installation of the sensor, please contact your local boat dealer.
GPS Antenna/Receiver Module
The LCX-27C, LCX-28C HD, LCX-37C, LCX-38 C HD, LCX-112C and LCX113C HD packages include the LGC-3000 GPS module. This device contains the unit's external antenna and receiver for GPS and WAAS signals. The antenna/receiver module comes with a 15-foot 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-3000 Module, bottom view (left) and top view (right).
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, connect it to the unit. The LGC-3000 can communicate with your GPS unit either directly (using the supplied extension cable) or through a NMEA 2000 network. NOTE: See the modules instruction sheet, publication part number 9880154-651, for complete installation instructions. In an automobile, you may achieve good results by simply placing the external antenna on the top of the dash, at the base of the windshield. A piece of the rubber non-skid shelf liner material available in recreational vehicle supply stores will help hold the antenna in place. This may not work well if you have a cab-over design pickup truck camper or motor home. If dashboard reception is poor, simply relocate the antenna module elsewhere on the vehicle for a clearer view of the sky.

This allows you to see the virtually instantaneous sonar returns better, just as you would on a flasher sonar unit. For more information on FasTrack, see its entry in this section.

Reset Options

This command will reset all features, options and settings to their original factory defaults. This is useful when you have changed several settings and want to return the unit to basic automatic operation. 1. Press MENU|MENU| to SYSTEM SETUP|ENT| to RESET OPTIONS|ENT. 2. Press to YES|ENT. 3. All the menus are cleared and the unit reverts to the Map Page at the 4000-mile zoom range, just as if you had turned it on for the first time. All options have been returned to the factory settings. 83

NOTE: Reset Options does not erase any waypoints, routes, plot trails, or sonar logs.

Reset Water Distance

The sonar chart's Digital Data display option includes a window that shows distance traveled, called Water Distance ("W Distance"). This information is calculated from an optional water speed sensor, not the GPS. The Water Distance window can be reset to zero using the Reset Water Distance command. Press MENU|MENU| to SONAR SETUP|ENT| to RESET WATER DISTANCE|ENT. The menus are cleared and water distance is reset to 0.00.

Set Keel Offset

This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the depth displayed by the digital depth, chart depth scale, chart cursor or fish symbols is not exact. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the actual depth is 31 feet. On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or lower engine unit can be several feet. In those cases, an inexact depth reading could result in grounding or striking underwater structure. The Keel Offset feature eliminates the need for the navigator to mentally calculate how much water is under his keel. Keel Offset lets you calibrate the digital depth: chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, first measure the distance from the face of the transducer to the lowest part of the boat. In this example, we will use 3.5 feet. This will enter as a negative 3.5 feet, which makes the depth indicators perform as if the transducer's lower in the water than it really is. 84

1. Press MENU|MENU| to SONAR SETUP|ENT. 2. Use to scroll down to KEEL OFFSET, then press ENT. The Keel Offset dialog box appears. Press to change the plus (+) sign to a minus () sign. 3. Press to the first number, then press to change the number to 3. 4. Press to the second number, then press to change that number to 5, then press EXIT. The depth indicators now accurately show the water depth beneath the keel. NOTE: If knowing the exact depth of water beneath the keel is less important, you can calibrate the depth indicators so that they show the actual water depth from surface to bottom. To do this, first measure the distance from the face of the transducer to the surface (the water line on the boat). In this example, we will use 1.5 feet. This will be entered as a positive 1.5 feet, which makes the depth indicators perform as if the transducer's higher in the water than it really is. 1. Press MENU|MENU| to SONAR SETUP|ENT. 2. Use to scroll down to KEEL OFFSET, then press ENT. The Keel Offset dialog box appears with a plus (+) sign at the front of the box. 3. Press to the first number, then press to change the number to 1. 4. Press to the second number, then press to change the number to 5 and press EXIT. The depth indicator now accurately shows the water depth from surface to bottom.
Sensitivity & Auto Sensitivity
Sensitivity controls the ability of the unit to pick up echoes. A low sensitivity level (from zero to 50 percent) excludes much of the bottom information, fish signals, and other target information. High sensitivity levels let you see this detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a solid bottom signal with some surface clutter. Automatic Sensitivity The default sensitivity mode is automatic. The unit bases the sensitivity level on water depth and conditions. When the unit is in the automatic mode, sensitivity automatically adjusts to keep a solid bottom signal displayed, plus a little more power. This gives it the capability to show fish and other detail. 85
Situations occur, however, when it becomes necessary to increase or decrease sensitivity. This typically happens when you wish to see more detail, so an increase in sensitivity is needed. Or when wave action and boat wakes create tiny air bubbles that clutter much of the water column. In that case, a decrease in sensitivity is necessary to reduce some of the clutter. The control bar used to adjust sensitivity up or down is the same whether the unit is in the automatic or manual mode. In automatic, you can adjust sensitivity up to 100 percent but the unit will limit your minimum setting. In auto, the unit will continue to make small adjustments, allowing for the setting you selected. In manual mode, you have complete control over sensitivity, with the ability to set it anywhere from zero to 100 percent. Once you select a level in manual, the unit will continue to use that exact sensitivity setting until you change it or revert to auto mode. To adjust sensitivity in auto mode: 1. Press MENU|ENT. 2. 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 Navigation Page.

The cross track error range is shown on the compass rose as a wide, white, corridor enclosing the course line. The outer edges of this white corridor represent lines that show the current cross track error range. The default for the cross track error range is 0.20 miles. For example, if the present position symbol touches the right cross track error line, then you are 0.20 miles to the right of the desired course. You need to steer left to return to the desired course. You can use the ZIN or ZOUT keys to change the cross track error range. A circular symbol depicting your destination (waypoint) appears on the screen as you approach the waypoint. Trip Time is the time that it will take to reach your destination at your present closing speed. You can also customize the time window to show Arrival Time instead. Arrival Time is the local time it will be when you arrive at the destination, based upon your present closing speed and track. The Navigation Page has its own menu, which is used for some advanced functions and for setting various options (Options and setup are discussed in Sec. 8.). To access the Navigation Page Menu, from the Navigation Page, press MENU. Map Page The Map Page screens show your course and track from a "bird's-eye" view. By default, this unit shows the map with north always at the top of the screen (This can be changed. See the topic Map Orientation, in Sec. 8.). If you're navigating to a waypoint, the map also shows your starting location, present position, course line and destination. You, however, don't have to navigate to a waypoint to use the map. Map Page is the default screen that appears when you turn on the unit. To get to the Map Page from another page: Press PAGES| or to MAP|EXIT. When the Map Page is displayed, a screen similar to the following figure appears. The arrow in the center of the screen is your present position. It points in the direction you're traveling. The map zoom range is the distance across the screen. This number shows in the lower right corner. In the example below, the range is 15 miles from the left edge of the map to the right edge of the map. The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its coverage area and the amount of mapping detail shown. There are 37 available map zoom ranges, from 0.05 miles to 4,000 miles.

GPS Quick Reference

Find Your Current Position
Finding your current position is as simple as turning the unit on. Under an unobstructed sky, the unit automatically searches for satellites and calculates its position in approximately one minute or less. If for some reason satellite acquisition takes longer, you may be inside a structure, a vehicle or in terrain that is blocking signal reception. To correct this, be sure you are positioned so the unit's antenna module has as clear a view of the sky as possible, then turn the unit off and back on again.
Moving Around the Map: Zoom & Cursor Arrow Keys
The presented map is from a bird's eye view. The current zoom range shows in the lower right corner of the screen. 1. Press the ZIN key (zoom in) to move in closer and see more detail in a smaller geographic area. 2. Press the ZOUT key (zoom out) to move farther away and see less map detail, but a larger geographic area. When you are traveling, the map will automatically move as you move. This keeps your current location roughly centered on the screen. You can manually pan or scroll the map northward, southward, eastward or westward by using the arrow keys, which launch the cross-hair map cursor. This allows you to look at map places other than your current position. To clear the cursor, press EXIT, which switches the map back to the current position or the last known position.
Use the cursor to determine the distance from your current position to any map object. Position the cursor over the object or landmark with the arrow keys. The distance, measured in a straight line, appears in the pop-up box. Press EXIT to clear the cursor.

Searching

Now that you've seen how the unit can find where you are, let's search for something somewhere else. Searching is one of the most powerful features in the Lowrance GPS product line. In this example, we'll look for the nearest fast-food restaurant. For more information on different types of searches, refer to Sec. 9, Searching. NOTE: This example requires the Point of Interest (POI) database included with a high detail MapCreate 6 custom map. After the unit has acquired a position: 1. Press WPT| to POI-RESTAURANTS. 2. You could search the entire restaurant category, but in this example we will narrow our search. Press to SUBCATEGORY column| to FAST FOOD CHAINS|ENT| to NEAREST|ENT. 3. The unit says it is calculating, then a list of restaurants appears, with the closest at the top of the list, and the farthest at the bottom of the list. The nearest is highlighted. 113

Radar Display Unit Software Update
Your display unit must have the latest software version to work with radar and the RIM 200. Depending on when you bought your display, it may require a software update. To avoid delays in setting up your radar system, your radar package includes an MMC or SD memory card with a software upgrade. 2007 Model Units You WILL NOT need to update the software version in 2007-model units which include: X510C, X515C DF sonars; LMS-520C, LMS-522C iGPS, LMS-525C DF, LMS-527C DF iGPS, LCX-27C, LCX-28C HD, LCX-37C, LCX-38C HD, LCX-112C, LCX-113C HD sonar/GPS combos; and GlobalMap 5200C, GlobalMap 5300C iGPS, GlobalMap 7200C, GlobalMap 7300C HD, GlobalMap 8200C, GlobalMap 8300C HD, GlobalMap 9200C, GlobalMap 9300C HD GPS units. 2006 Model Units If you are using a 2006-model unit, access the software information screen to make sure its software version is 1.7 or greater. If the version of software in your unit is less than 1.7 you will need to install the software update contained on the card that came with your RIM 200.
