2. The transducer should be installed with its face pointing straight down, if possible. 3. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 4. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires.
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.
Transom Transducer centerline
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 waves or wakes. 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 Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. 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. Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on some hulls that sit with the bow high when at rest or at slow trolling speeds. Follow the procedure listed in the shoot-thru-hull installation section at the end of this lesson to determine if you can satisfactorily shoot through the hull. TRANSOM TRANSDUCER ASSEMBLY AND MOUNTING The best way to install these transducers is to loosely assemble all of the parts first, place the transducer's bracket against the transom and see if you can move the transducer so that it's parallel with the ground. The following instructions sometimes vary depending on the mounting bracket that came with your transducer. Single-frequency Skimmers come with a one-piece stainless steel bracket, while dual-frequency Skimmers come with a two-piece plastic mounting bracket. Use the set of instructions that fits your model. 1. Assembling the bracket. A. One-piece bracket: Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter "A" aligned with the dot stamped into the metal 16

Spread epoxy here

Sand this surface
Epoxy transducer to hull.
2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, because it will cause bubbles to form in the epoxy. Apply a small amount on the face of the transducer as shown above, then spread a small amount onto the sanded area on the hull. Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit.
Speed/Temperature Sensors
These units can accept additional temperature sensors which can be used to monitor the temperature of surface water, a live well or some other location. The SeaCharter 320DF can accept as many as three temperature sensors, and the FishElite 320 can accept as many as two. These units can also accept an optional speed sensor for showing speed and distance traveled. However, the FishElite 320 can only use one accessory at a time, so if you would like to use a speed sensor and a second temperature sensor at the same time, you will need a combination device. If you own a SeaCharter 320DF and would like to use a speed sensor and a second temperature sensor at the same time, you will need an optional MY-4X cable. NOTE: These units are packed with a transducer containing a built-in temp sensor. The SeaCharter 320DF package also includes a speed sensor. If you have a FishElite 320 and want a speed sensor or additional temp sensor, see the Accessory Ordering Information in the back of this manual. If a second temp sensor is used, it must be the model TS-2U for the FishElite and the model TS-2X for the SeaCharter. These sensors have a fixed electronic "address" which designate them as the second of two temp sensors. Dual temperatures are only displayed on the Full Chart page. The Large Digital page will only display the primary temperature sensor. See the following wiring diagrams for temperature and speed sensor combinations by unit. NOTE: SeaCharter 320DF units have been packed with one of two sensor/cable configurations. One includes an MY-4X cable and SP-X sensor and is shown on page 27. The other uses the SPY-X sensor and does not include the MY-4X; it is shown on page 184. 26

Log Sonar Chart Data

If you have an MMC installed in the unit, the sonar data shown on the screen can be saved to the MMC. This can be played back at any time (to play a recorded sonar chart log, see the entry in this section for Sonar Simulator). If you have a personal computer and Internet access, visit our web site, www.lowrance.com, and download the free Sonar Viewer and the emulator for your unit. These programs will allow you to replay sonar logs on your personal computer.

Note that the Steering Arrow always points directly to the destination you are navigating toward. In this case, the boater is headed on a northwesterly course of 275. Since the helmsman is on course, the Steering Arrow is pointing straight ahead. If the helmsman veered off course, the arrow would show which direction to steer to get back on course toward the destination. At right, Sonar Page with Overlay Data turned on. This example shows Depth, Ground Speed and the Track the boat is following.
NOTE: Some data types can be displayed in only one font size. If that is the case, the Data Size box will not be displayed for that data type.
Ping Speed & HyperScroll

Sensitivity & Auto Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. Sensitivity can be adjusted, because water conditions vary greatly. 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 good solid bottom signal with Grayline and 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 is automatically adjusted to keep a solid bottom signal displayed, plus a little more power. This gives it the capability to show fish and other detail. However, situations occur when it becomes necessary to increase or decrease the sensitivity. This typically happens when you wish to see more detail, so an increase in sensitivity is indicated. Or, wave action and boat wakes can create enough tiny air bubbles to clutter much of the water column. In that case, a decrease in sensitivity is indicated 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 ad75
justments, 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.)
To adjust sensitivity in manual mode: 1. First, turn off Auto Sensitivity: from the Sonar Page, press MENU| to AUTO SENSITIVITY|ENT. 2. Press to SENSITIVITY|ENT and the Sensitivity Control Bar appears. Press or to pick a different sensitivity setting. When it's set at the desired level, press EXIT. To turn Auto Sensitivity back on: From the Sonar Page, press MENU| to AUTO SENSITIVITY|ENT|EXIT. NOTE: To return to the original factory setting for Auto Sensitivity, see the entry in this section on Reset Options. If sensitivity is in manual mode, the Reset Options command will switch back to Auto and reset the factory setting at the same time.

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. The Satellite Status Page shows you the quality and accuracy of the current satellite lock-on and position calculation. WARNING: Do not begin navigating with this unit until the numbers have stopped flashing!
Satellite Status Page. Left view indicates unit has not locked on to any satellites and does not have a fix on its position. Center view shows satellites being scanned. Right view shows satellite lock-on with a 3D position acquired (latitude, longitude and altitude), and WAAS reception.
This screen shows a graphical view of the satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the center of the chart is directly overhead. The small inner ring represents 45 above the horizon and the large ring represents the horizon. North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north. The GPS receiver is tracking satellites that are in bold type. The receiver hasn't locked onto a satellite if the number is grayed out, therefore it isn't being used to solve the position. Beneath the circular graph are the bar graphs, one for each satellite in view. Since the unit has twelve channels, it can dedicate one channel per visible satellite. The taller the bar on the graph, the better the unit is receiving the signals from the satellite. The "Estimated Position Error" (horizontal position error) shown in the upper left corner of the screen is the expected error from a benchmark location. In other words, if the EPE shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. This also gives you an indicator of the fix quality the unit currently has. The smaller the position error number, the better (and more accurate) the fix is. If the position error flashes dashes, then the unit hasn't locked onto the satellites, and the number shown isn't valid. 95
The Satellite Status Page has its own menu, which is used for setting various options. (Options and setup are discussed in Sec. 8). To access the Satellite Status Page Menu, from the Status Page, press MENU. Navigation Page This screen has a compass rose that not only shows your direction of travel, but also the direction to a recalled waypoint. To get to the Navigation Page: Press PAGES| or to NAVIGATION|EXIT. The navigation screen looks like the one below when you're not navigating to a waypoint or following a route or trail. Your position is shown by an arrow in the center of the screen. Your trail history, or path you've just taken, is depicted by the line extending from the arrow. The arrow pointing down at the top of the compass rose indicates the current track (direction of travel) you are taking.

Transfer Custom Maps and GPS Data Files
Custom Maps: Custom maps work only from the MMC card or SDC card. When a card containing a Custom Map File is loaded into the unit, the unit automatically loads the map into memory when the unit is turned on. Instructions for copying Custom Map Files to an MMC are contained in the instruction manual for your MMC card reader and MapCreate 6 software. For instructions on inserting an MMC into the unit, see Section 2, Installation/Accessories. 118
NOTE: To load a Navionics chart, see Sec. 8 for the entry Navionics Charts. GPS Data files: GPS Data Files contain waypoints, routes, trails and event marker icons. Instructions for copying GPS Data Files between your computer and an MMC are contained in the instruction manual for your MMC card reader and MapCreate 6 software. GPS data automatically recorded in the unit's internal memory must be saved to the MMC (as a GPS Data File) in order to store it on your personal computer. GPS Data Files stored on an MMC must be copied from the card to the unit's internal memory before the unit can read them. Here's how: 1. Insert the MMC into your unit. Press MENU|MENU| to SYSTEM SETUP|ENT| to TRANSFER MY DATA|ENT and the screen below appears.
The Transfer My Data submenu asks if you want to save data to the MMC or load data from the MMC into the unit's memory.
2. The Transfer My Data menu includes a message which tells you if an MMC is present or not. If no MMC is present, you must first insert a card into the unit in order to activate the Load or Save commands. To transfer data from the unit to the MMC: press ENT (for SAVE.)

Routes

A route is a series of waypoints, linked together in an ordered sequence, that's used to mark a course of travel. You can visualize a route as a string of beads: The beads represent waypoints and the string represents the course of travel connecting waypoint to waypoint. The course from one waypoint to the next is a leg; routes are composed of one or more legs. The legs of all GPS routes are based on straight lines between waypoints. 123
A route provides the automatic capability to navigate through several waypoints without having to reprogram the unit after arriving at each waypoint. Once programmed into the GPS unit, a route provides the option of navigating forward through the route waypoints or in reverse order (you can even begin navigating in the middle of a route!) Create and Save a Route You have the option of creating and editing a route in the unit, or you can make a route on your computer with our MapCreate 6 software.

PC-created Routes

MapCreate is the easiest method for preparing a route, simply because your PC's larger screen, keyboard and mouse are easier to manipulate than the gimbal-mounted unit. To load a MapCreate route into the unit, follow instructions in MapCreate's manual for creating a route and saving it as part of a GPS Data File (file format *.usr). Copy the GPS Data File to an MMC and insert the MMC in the unit. (See Section 2 for instructions on installing MMCs. To load the GPS Data File into the unit's memory, see the entry on Transfer Custom Maps & GPS Data Files in Sec. 6, Basic GPS Operations.)

Update Trail Criteria (Auto, Time, Distance)
The options are automatic, time, or distance. When it's in the default automatic mode, the unit doesn't update the plot trail while you're traveling in a straight line. Once you deviate from a straight line, the unit "drops" a plot point (trail waypoint) onto the trail. This conserves plot trail points. If a plot trail uses all of the available points allotted to it, the beginning points are taken away and placed at the end of the trail. From the Trails Menu, press to OPTIONS|ENT| to UPDATE CRITERIA. Press or to select criteria type|ENT.
Trail Update Rate (Time, Distance)
You can update a trail by time, with a range from 1 second to 9999 seconds; the default is 3 seconds. You can update by distance, with a range from 0.01 mile/nm/km to 9.99 mile/nm/km; the default is 0.10 mi. With one of the Update Criteria selected, use the cursor arrows to 161

How GPS Works

You'll navigate faster and easier if you understand how the 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 page 13. If you're new to GPS, read on. Think of your unit as a small but powerful computer. The unit includes a keypad and a screen with menus so you can tell it what to do. The screen also lets the unit show your location on a moving map, as well as point the way to your destination. This gimbal-mounted unit uses an internal antenna and receiver, which makes the system work like your car radio. But instead of your favorite dance tunes, this receiver tunes in to a couple of dozen GPS satellites circling the earth. (It will also listen to WAAS satellites in orbit, but we will delve into that in the segment introducing you to GPS and WAAS.) Your unit listens to signals from as many satellites as it can see above the horizon, eliminates the weakest signals, then computes its location in relation to those satellites. Once the unit figures its latitude and longitude, it plots that position on the moving map shown on the screen. The whole process takes place several times a second! The performance doesn't stop there. Stored in the permanent memory of each unit is a basic background map of the entire world. We lock it in here at the factory you can not change or erase this map. The background map is suitable for many navigation chores, but for maximum accuracy and much more detail, you need our optional map6
making software, MapCreate 6 or one of our special plug-and-play mapping cards. Some unit features such as searching for businesses and addresses won't work without a custom MapCreate map. There is so much detail in our background map (and even more in MapCreate) that we'll describe their contents and differences in Section 3, Basic GPS Operations, on page 93. Another portion of the units onboard memory is devoted to recording GPS navigation information, which includes waypoints, event marker icons, trails and routes. This lets you look back the way you came. Think of this data storage like the hard drive memory in a computer or a tape in a cassette tape recorder. You can save several different GPS data files, 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 Eagle GPS or sonar/GPS units or even personal computers. This unit has one more thing in common with a personal computer. Just as computers have a floppy disk drive for storing and exchanging files, the unit has a slot for an MMC (MultiMedia Card) or SD card (Secure Digital card) flash memory card. These solid-state memory devices are about the size of a postage stamp, but can hold data ranging from 8 MB to 1 GB in size. (Compare that to a floppy disk's 1.44 MB capacity!) This unit uses all that MMC space for two key GPS purposes. You can backup your onboard GPS Data Files by copying them to the MMC. Since the MMC is removable (like a floppy disk or a cassette tape), you can store these GPS Data Files on a personal computer equipped with an MMC card reader. (Or store them on a pocketful of MMCs, if you don't have a computer.) Our MapCreate mapping software can save, edit or create its own GPS Data Files, which can be copied to the MMC and then loaded from the MMC into the unit's memory. (NOTE: No matter where they come from, GPS Data Files must be loaded from the MMC into memory before the unit can use them.) The other key GPS use for MMCs is storage of special high-detail, custom maps, which you can produce on your computer with our MapCreate software. These MapCreate custom maps contain much greater detail than the basic background map. These Custom Map Files (file format *.lcm) can also be shared between Eagle GPS or sonar/GPS units and personal computers. This unit automatically reads Custom Map Files directly from the MMC or SD card. To use a custom map, all you need to do is slide an MMC containing a map into the unit.

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. 3. The transducer should be installed with its face pointing straight down, if possible. For shoot-thru applications: Many popular fishing boat hulls have a flat keel pad that offers a good mounting surface. On vee hulls, try to place the transducer where the deadrise is 10 or less.

Deadrise less than 10

Strakes Pad Vee pad hull (left); Vee hull (right). A pod style transducer is shown here, but the principle is the same for Skimmers inside a hull.
4. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires.
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.

Transducer centerline

Hull bottom

Align transducer centerline with hull bottom. A dual frequency transducer (left) and a single frequency transducer (right).
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.There, however, 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 waves or wakes. 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 passes through the hull and into the water. This differs from a bolt-thru-hull installation (often called "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 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. 16

2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratchets. Temporarily slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A" position is correct for your hull. If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3A. If it doesn't, repeat step 2A, but use a different alignment letter until you can place the transducer on the transom correctly.

B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A" positions are correct for your hull.

If the transducer's face isn't parallel with the ground, remove and disassemble the transducer and ratchets. Place the ratchets into the bracket holes with the letter "B" aligned with the bracket alignment mark. Place them on the transducer aligned with the 12 o'clock position on the transducer stem. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat step 2B, but use a different alignment letter until you can place the transducer on the transom correctly. 3. Assembling the transducer. A. One-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the following figure. Don't tighten the lock nut at this time.

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. We'll discuss all of those features and options in Sec. 4, but to show you how easy this unit is to operate, the following page contains a simplified, 10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory.

For quicker sensitivity adjustments, try leaving the Sensitivity Control Bar on the screen as the chart scrolls. You can see the changes on the screen as you press the up or down arrows. This is handy when there's a lot of clutter in the water and you are matching the sensitivity to rapidly changing water conditions.

Sonar Chart Mode

The default color scheme for the sonar chart is white background, but there are other variations. You can select the chart to be displayed in Grayscale, Reverse Grayscale, Blue Background, Nightview, IceView, or Bottom Color Tracking. To change the chart mode color scheme: 1.

2,000, but the unit can record trails 9,999 points long). When the point limit is reached, the unit begins recording the trail over itself. With the default auto setting, this unit creates a trail by placing a dot (trail point) on the screen every time you change directions. (The methods used for creating a trail and the trail update rate can both be adjusted or even turned off. See Sec. 8 for Trail Options.) To preserve a trail from point A to point B, you must "turn off" the trail by making it inactive before heading to point C or even back to point A. When the current trail is set inactive, the unit automatically creates and begins recording a new trail. To Save a Trail 1. Press MENU|MENU| to MY TRAILS|ENT.

As you leave the Edit Trail menu, you will notice that a new trail starts with a new sequential number. In the example figure below, the new trail is number 4, showing zero points. Note that Trail 3 is inactive, but it is still visible on the map.
New trail, named "Trail 4," is created when Trail 3 is made inactive. Any new travel will be recorded in this trail, which is active and visible. Trails do not need to be visible in order to be active.
You can save and recall up to 10 different plot trails, which can also be copied to your MMC for archiving or for transfer to your MapCreate software.
Another quick way to stop recording one trail and begin a new one is to use the New Trail command: Press MENU|MENU| to MY TRAILS|ENT|ENT. Caution: You also have the option of completely turning off trail recording, under the trail Options command. However, if the Update Active Trail option is left turned off, it will cancel the automatic trail creation feature.

Displaying a Saved Trail

The active trail is automatically displayed on the map (the "Visible" option) with the factory default settings. You can selectively turn trail display off and on for any saved or active trail. In the Saved Trails List, visible trails have a check mark in front of the trail name. To turn off trail display: 1. Press MENU|MENU| to MY TRAILS|ENT. 2. Press to select the desired Trail Name from the Saved Trails List. Press ENT. 3. Press to VISIBLE|ENT. To return to the main page display, press EXIT repeatedly. 110

Navigating Trails

There are three methods for following a trail: visual trailing, navigating a trail (forward) and backtracking a trail (backward). Try each method to see which you prefer. Visual trailing is the simplest method. It uses only the Map Page and requires no menu commands at all. The technique works the same if you are running a trail forward (from start to end) or backward (from end to start.) However, visual trailing provides no navigation information during the trip, such as the time to your destination. The other two methods provide a full range of navigation data and work with both the Map Page and Navigation Page. The only difference between them is "navigating a trail" follows a trail forward (from start to end) while "backtracking" follows a trail in reverse (from end to start.) When hiking at walking speed with a hand-held GPS, we often just use visual back trailing because it is a bit better at following each little turn on a foot path. At faster speeds, such as the highway or on the water, the Navigate Trail and Backtrack Trail commands are handy. Visual Trailing 1. On the Map Page, zoom (ZIN or ZOUT) so your trail is visible. 2. Begin moving and watch the Map Page. Walk or steer so your current position arrow traces along the trail you made.

Generally, when using this method, the smaller the zoom range, the more accurately you will be able to steer along the trail. Navigate a Trail The following figures illustrate the menu sequence for navigating a trail. 1. Press MENU|MENU| to MY TRAILS|ENT. 2. Press to enter the Saved Trail list, then use to select the desired Trail Name|ENT. 3. Press to NAVIGATE|ENT|ENT. The unit begins showing navigation information along the trail. NOTE: If you are located at or near the beginning of the trail, the arrival alarm will go off when you hit Enter. Press EXIT to clear the alarm. 5. Now begin moving and let your unit guide you. 6. When you reach your destination, cancel navigation: press MENU|MENU| to CANCEL NAVIGATION|ENT. A confirmation message will appear. Press |ENT. 111

Section 8: System & GPS Setup Options
This unit has several GPS alarms. The factory default setting has all of these but the anchor alarm turned on. You can turn the alarms off and on and change their distance settings. You can set an arrival alarm to flash a warning message and sound a tone when you cross a preset distance from a waypoint. For example, if you have the arrival alarm set to.1 mile, then the alarm will flash a message when you come within.1 mile of the recalled waypoint. The off course alarm warns you when your track drifts too far to the right or left of the course line to the waypoint. For example, if the alarm is set to.1 mile, then the alarm flashes a message if you drift.1 of a mile or more to the right or left of the line to the waypoint. The anchor alarm is triggered when you drift outside of a preset radius.

4. When your adjustments are finished, return to the main page display by repeatedly pressing EXIT. NOTE: Anchor Alarm - The anchor alarm may be triggered even when you're sitting still. This typically happens when using small (less than.05 mile) anchor alarm ranges. Arrival Alarm - If you set the arrival alarm's distance to a small number and you run a route (see the Navigate Routes segment), this unit may not show navigation data to the next waypoint, once you arrive at the first one, since you may not be able to come close enough to the first waypoint to trip the arrival alarm.

3. In a moment, your present position marker arrow appears on the map in the location you selected with the cursor. The unit will consider that spot as its last known position until changed by a live satellite lock-on or a new simulator location.

Map Auto Zoom

This receiver has an auto zoom feature that eliminates much of the button pushing common with other brands of GPS receivers. It works in conjunction with the navigation features. First, start navigation to a waypoint. Then, with the auto zoom mode on, the unit zooms out until the entire course shows, from the present position to the destination waypoint. As you travel toward the destination, the unit automatically begins zooming in one zoom range at a time always keeping the destination on the screen. To turn this feature on, from the MAP PAGE, press MENU| to AUTO ZOOM|ENT|EXIT. Repeat these steps to turn it off.

Map Data

This menu lets you turn the map off, if desired (which turns the map screen into a GPS plotter); turn off or on the pop-up map info boxes; draw the map boundaries or boxes around the areas of high detail; or fill land areas with gray.

This menu lets you select Navionics Maps; for instructions, see the Navionics Charts entry in this section. To get to Map Data: From the Map Page, press MENU| to MAP DATA|ENT.

Map Overlays (Range Rings; Lat/Long Grid) The map screen can be customized with four range rings and/or grids that divide the plotter into equal segments of latitude and longitude. Range rings are handy for visually estimating distances on the map. The ring diameters are based on the current zoom range. For example: at the 100 mile zoom, the screen will show two rings with your current position in the center. The large ring touching the left and right sides of the screen is 100 miles in diameter (same as the zoom range). The second smaller ring is 50 miles in diameter (always 1/2 the zoom range). The distance from your current position to the smaller ring (the ring's radius) is 25 miles (always 1/4 the zoom range). With the arrow keys and map cursor, you can scroll the map to see the third and fourth rings. In this example, the distance to the third ring is 75 miles and distance to the fourth ring is 100 miles from your current position. To set range rings: From the Map Page, press MENU| to MAP DATA|ENT. Press to RANGE RINGS. With the option highlighted, press ENT to turn it on (check) and turn it off (uncheck). After the option is set, press EXIT|EXIT to return to the main page display. 141
