WARNING!

A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION.

CAUTION

When showing navigation data to a position (waypoint), a GPS unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only take advantage of all available navigation tools when traveling to a waypoint, but will also visually check to make sure a clear, safe path to the waypoint is always available.

WARNING!

When a GPS unit is used in a vehicle, the vehicle operator is solely responsible for operating the vehicle in a safe manner. Vehicle operators must maintain full surveillance of all pertinent driving, boating or flying conditions at all times. An accident or collision resulting in damage to property, personal injury or death could occur if the operator of a GPS-equipped vehicle fails to pay full attention to travel conditions and vehicle operation while the vehicle is in motion.

Section 1: Read Me First!

How this manual can get you out on the road, fast!

Welcome to the exciting world of GPS satellite navigation! We know you're anxious to begin finding your way with this hand-held technology, but we have a favor to ask. Before you grab the batteries and head outside, please give us a moment or two to explain how our manual can help you get the best performance from this remarkable little GPS unit.

First, we want to thank you for buying an iFINDER H2OC. Whether you're a first-time user or a professional navigator, you'll discover that the iFINDER is a true pocket-sized, full-featured mapping GPS receiver. When you team an iFINDER with one of our specialized maps or our custom mapping software MapCreate 6, you have an incredible combination. No other consumer GPS mapping system on the market offers so much information and so many features in one package.

Our goal for this book is to get you on the road or out to the woods and water fast, with a minimum of fuss. Like you, we'd rather spend more time traveling, and less time reading the manual!

So, we designed our book so that you don't have to read the whole thing from front to back for the information you want. At the start (or end) of each segment, we'll tell you what content is coming up next. If it's a concept you're already familiar with, we'll show you how and where to skip ahead for the next important topic. We've also made it easy to look up any tips you may need from time to time. Here's how:

The manual is organized into seven sections. This first section is an introduction to Lowrance GPS. It tells you the basics you need to know before you can make the unit look around and tell you where you are.

Section 2 will help you get the batteries and MultiMedia Card (MMC) correctly installed in your iFINDER. We'll also tell you about some of the accessories available for your unit.

Section 3 is the heart of our book, Easy Mode Operation. It will introduce you to the basic GPS functions. We lead off this section with a onepage Easy Mode Quick Reference. (If you've already figured out how to load the batteries yourself, and you just can't wait any longer, turn to the Quick Reference on page 28 and head outside with your iFINDER!)

The rest of Section 3 contains short, easy-to-scan lessons that follow one another in chronological order. They're all you'll need to know to find your way on the water or in the wilderness quickly.

Easy Mode operation will meet the navigation needs of many users. But, after you've learned the basics (or if you already have some GPS experience), you may want to try out some of the iFINDER's many advanced navigation features. That brings us to Section 4, Advanced Mode Operation. After we introduce the Advanced Mode menus and submenus, this section contains the rest of the iFINDER's command functions, organized in alphabetical order.

When you come to a GPS menu command on the iFINDER screen, you can look it up in the manual by skimming over the table of contents or index, just flipping through Section 3 or scanning through the command portion of Section 4.

The iFINDER is ready to use right out of the box, but you can fine tune and customize its operation with dozens of options. We describe how to use general system options along with GPS options in Section 5, System Setup and GPS Setup Options. This section covers both Easy Mode and Advanced Mode options.

In Section 6, we go into more detail on one of the iFINDER's most remarkable capabilities — Searching. We'll introduce a couple of search examples in both the Easy and Advanced mode sections, but there are so many map items you can search for, we had to give this function its own section in the manual! For example, did you know the iFINDER can look up business phone numbers, functioning as a virtual Yellow Pages? We’ll show you how in Section 6.

Finally, in Section 7, we offer Supplemental Material, including a list of the GPS datums used, warranties, and customer service information.

Now, if you're into the fine details, glance over the next segment on specifications to see just how much GPS power you hold in your hand. It's important to us (and our power users), but if you don't care how many waypoints the iFINDER can store or how long the batteries last, skip ahead to important information on how the iFINDER works, on page 4.

NOTE:

The above memory capacities refer only to the iFINDER's on-board memory. The amount of GPS data you can record and save for recall later is only limited by the number of MMC cards you have.

How the iFINDER H2Oc Works

You'll navigate faster and easier if you understand how the iFINDER 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 11. If you're new to GPS, read on, and you can later impress your friends with your new-found knowledge.)

First, think of your iFINDER as a small but powerful computer. (But don't worry — we made the iFINDER easy to use, so you don't need to be a computer expert to find your way!) The iFINDER includes a keypad and a screen with menus so you can tell it what to do. The screen also lets the iFINDER show your location on a moving map, as well as point the way to your destination.

This pocket-sized computer also contains an antenna and specialized scanning receiver, something 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 in to the WAAS and satellites in orbit, but more about that in the upcoming segment introducing you to GPS and WAAS.)

The iFINDER 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 the remaining satellites. Once the iFINDER figures its latitude and longitude, it plots that position on the moving map shown on the screen. While the screen is updated once a second, your iFINDER is making these internal calculations and determining its position several times a second!

The performance doesn't stop there. Stored in the permanent memory of each iFINDER is a basic background map of the entire world. We lock it in here at the factory — you can't change or close this map.

Another portion of the iFINDER's 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 and over again. Like any computer file, these GPS Data Files (file format *.usr) can be shared between iFINDERs, other Lowrance GPS units, sonar/GPS units and even personal computers.

The iFINDER has one more thing in common with a personal computer. Just as computers have a floppy disk drive for storing and exchanging files, the iFINDER has a slot for an MMC (MultiMedia Card) or SD (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!) The iFINDER uses all that MMC space for two key purposes.

First, 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 iFINDER's memory.

NOTE:

No matter where they come from, GPS Data Files must be loaded from the MMC into memory before the iFINDER 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 MapCre-

ate 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 iFINDERs, other Lowrance GPS or sonar/GPS units and personal computers.

You make your own Custom Map Files with our MapCreate software, but you don't have to. We also sell ready-to-use FreedomMaps . These custom maps are pre-loaded on MMCs. (No computer work required!).

The iFINDER 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.

Introduction to GPS, WAAS and EGNOS

Well, now you know the basics of how the iFINDER does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page 11, so you can install the batteries. Or you might want to see how our text formatting makes the manual tutorials easy to skim. If that's the case, move on to "How to Use This Manual" on page 8. But, if you want to understand the current state of satellite navigation, look over this segment describing how GPS and its new companions WAAS and EGNOS work together to get you where you're going.

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.S. and its allies. Civilian use was also available at first, 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 that 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. These signals can be easily blocked by trees, buildings, an automobile roof and even your body.

Like most GPS receivers, the iFINDER 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 all are calculated from position information. Therefore, in order for the iFINDER to determine direction of travel, you must be moving and the faster, the better. This is not to say that it won’t work at walking or trolling speeds — it will. There will be more "wandering" of the data shown on the display.

GPS alone is plenty accurate for route navigation, but the U.S. Federal Aviation Administration has special aircraft navigation needs that go beyond basic GPS. Consequently, the FAA has developed a program to boost GPS performance with its Wide Area Augmentation System (WAAS). The FAA commissioned the system on July 11, 2003. EGNOS (European Geostationary Navigation Overlay Service) is the European equivalent of WAAS. Like WAAS, it was created to make GPS position calculation more accurate.

WAAS is designed to increase GPS accuracy to within 7.6 meters vertically and horizontally, but according to the FAA, it consistently comes within 1-2 meters horizontal and 2-3 meters vertical. It does this by broadcasting correction signals on GPS frequencies. Your unit automatically receives both GPS and WAAS signals.

There, however, are some fringe areas of the U.S., including parts of Alaska, that do not yet receive robust WAAS coverage. Continued WAAS development is planned to extend WAAS coverage in the years to come.

WAAS boosts 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 can sometimes block the WAAS signal from ground receivers.

You'll find that using your GPS receiver is both easy and amazingly accurate. It’s easily the most accurate method of electronic navigation available to the general public today. Remember that 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 can’t know what’s between you and your destination. It’s up to you to safely navigate around obstacles, no matter how you’re using this product.

How to use this manual: typographical conventions

Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type. So, if you're in a real hurry (or just need a reminder), you can skim the instructions and pick out what menu command to use by finding the boldface command text. The following paragraphs explain how to interpret text formatting for those commands and other instructions:

Arrow Keys

The arrow keys control the movement of dotted crosshairs lines (the cursor) on your mapping screen. The arrow keys also help you move around the iFINDER menus so you can execute different commands. They are represented by symbols like these, which denote the down arrow key, the up arrow, the left arrow and the right arrow: ↓ ↑ ← →.

Keyboard

The other keys perform a variety of functions. When the text refers to a key to press, the key is shown in bold, sans serif type. For example, the "Enter/Save" key is shown as ENT and the "Menu" key is shown as MENU.

Menu Commands

A menu command or a menu option will appear in small capital letters, in a bold sans serif type like this: ADVANCED MODE. These indicate that you are to select this command or option from a menu or take an action of

some kind with the menu item. Text that you may need to enter or file names you need to select are shown in italic type, such as trail name.

Instructions = Menu Sequences

Most functions you perform with the iFINDER are described as a sequence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading.

For example, instructions for backtracking a trail in Easy Mode would look like this:

1.Press MENU|↓ to NAVIGATE TRAIL|ENT.

2.Now, begin moving and follow your iFINDER.

Translated into complete English, step 1 means: "Press the Menu key. Next, press the down arrow key to scroll down the menu and select (highlight) the Navigate Trail menu command. Finally, press the Enter key."

Also note that throughout this text, we will refer to the iFINDER H2OC as iFINDER, or as the unit.

Notes

Section 2:

Installation & Accessories

Power

The iFINDER operates from AA batteries or on 3 volts DC using an optional external power cable with a cigarette lighter adapter. When the power cable is used, the iFINDER automatically switches to external power. If the external power fails, the unit will switch to battery power.

Flash memory will keep your stored data safe and accessible for the life of the product. After the unit is turned off, no battery or external power is needed to store your data.

Batteries

The unit requires two, 1.5-volt AA batteries. We recommend you use alkaline batteries for the best trade-off between battery life and cost. We recommend DURACELL brand, but other brands will work. If you're looking for an extended-life battery, the Duracell ULTRA battery has performed well in our tests.

You can also use rechargeable AA alkaline batteries, such as those made by RAYOVAC , or rechargeable AA nickel metal hydride (NiMH) batteries. We do not recommend nickel cadmium (NiCd) rechargeable batteries because we tend to get poor battery life from them.

Rechargeable alkaline batteries will not last as long as standard alkaline batteries. Rechargeable NiMH batteries, however, should give you suitable battery life.

Lithium batteries are lighter than alkaline, and with some brands of lithium batteries, the iFINDER H2OC will float. We've tested the iFINDER H2OC using Energizer e2 lithium batteries, and it remained afloat.

NOTE:

The battery gauge on the Satellite Status Page may not read accurately with some battery brands because discharge rates can vary significantly. This is especially true for rechargeables. This battery gauge was calibrated for alkaline batteries.

Do not mix different battery types. Mixing battery types may cause leakage. (For example, don’t use both alkaline and NiMH batteries at the same time, and don't use standard alkalines with rechargeable alkalines.)

Turn the unit over so that the back is facing you. With your thumb or nail, pull back on the small clip to release the battery cover latch as shown in the following images. Once the latch is released, pull the battery cover out of the grooves in the bottom of the case.

Remove the iFINDER battery cover.

Install the batteries according to the embossed signs in the battery compartment. They show the correct polarity. Point the positive pole of the upper battery to the left; point the positive pole of the bottom battery to the right.

NOTE:

Inside the battery compartment is a rotating MMC card lock. The grip on this lock must be turned parallel with the direction of the batteries for them to fit properly.

Replace the battery compartment cover. First, align the latch tabs at the bottom of the cover with the slots at the case's base. Press the cover into place, then firmly push up on the clip at the top of the cover until it latches in place. There is usually an audible click when the latch engages.

Replace battery compartment cover. Align tabs with slots in the base (left). Press latch firmly until it clicks (right).

Cigarette Lighter Power Adapter

To use external DC power, plug the power cable's cigarette lighter adapter into a cigarette lighter receptacle. Next, pull aside the rubber cover on the bottom of the unit and insert the other connector as shown in the following image. A small clip on the connector should hold the connector in place.

Attach external power cable to the iFINDER.

WARNING:

Do not remove the cigarette lighter adapter and splice the exposed wires directly to a 12-volt power system. The cigarette lighter adapter contains in the plug a protective fuse and a voltage regulator to convert 12 volts down to about 3 volts. Without this regulator, connecting your unit to a 12-volt power source will destroy the unit. This damage will not be covered by your warranty.

The iFINDER can use two other optional external cables to supply a NMEA/serial data connection or a combination of power and data. These cables are discussed in the following segment on NMEA connections.

NMEA Cable Connections

NMEA is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA interface on this unit and receive positioning information. The unit can exchange information with any device that transmits or receives NMEA 0183 data.

To exchange NMEA data, Lowrance offers an optional data only cable and a power/data combo cable:

The PC-DI7 is a NMEA/serial communications cable. It has a standard female DB-9 connector on one end to attach your unit to a computer's serial communications port.

The PC-DI8 combines a cigarette lighter power adapter with a DB-9 plug for a NMEA/serial com port connection to a laptop computer or other device. This is our favorite cable for connecting the iFINDER H2OC to a laptop computer in a RV or other vehicle. By transmitting NMEA data to the computer, you can get live position data for GPScompatible mapping software.

You can also run one of our free Lowrance GPS emulators on your laptop and operate it with real-time position information.

To use it, plug the power adapter into a cigarette lighter socket, plug the DB-9 connector into a serial port on the computer and attach the cable to the iFINDER. Then see "Com Port Configuration" in Sec. 5.

MMC or SD Memory Card Installation

Your iFINDER uses a MultiMedia Card to store information, such as custom maps, waypoints and other GPS data. The unit can also use Secure Digital Cards (SD cards) to store information.

NOTE:

Throughout this manual, we will use the term MMC, but just remember your unit can use an MMC or SD card to store data.

Both of these solid-state flash memory devices are about the size of a postage stamp. A SD card is slightly thicker than an MMC. As this manual went to press, MMC and SD cards were available in storage capacities of up to 1 GB.

Additional MMC cards are available from LEI Extras. See ordering information inside the back cover of this manual. MMCs and SD cards are also available at many consumer electronics stores.

The MMC slot is located in the battery compartment, beneath the batteries on the right side of the unit. The contact pins are springy, to make it easier to insert and remove a MMC card.

Lowrance iFinder H2Oc Operation Instructions

To remove an MMC

1.Remove battery compartment cover.

2.Remove batteries, if present.

3.Hold unit facedown in right hand. Use your thumb or index finger and press down on the center of the MMC label.

5.Turn the plastic rotating card lock until it holds the card firmly in place with the grip parallel to the direction of the batteries.

6.Replace the batteries and battery cover.

FreedomMaps

FreedomMaps are pre-made custom maps that cover multiple states, provinces, countries or other geographic regions on a single memory card. They give you all the features found in our MapCreate™ mapping software, but without the necessity of using a computer. FreedomMaps are available for the United States, Canada and Europe. In 2004, FreedomMaps with topographic contours became available for the United States and Canada.

Like custom maps built in MapCreate, the custom map on a FreedomMap card contains all of these features: rivers/lakes/tributaries; more than 60,000 critical navigation aids; more than 10,000 wrecks/obstructions in coastal and Great Lakes waters; interstate/federal/state highways; interstate exit services; searchable Points-of-Interest (POI) database including: airports, hotels, restaurants, entertainment, emergency services; rural roads and city streets; cities and towns; railways; key landmarks; searchable street intersections and street addresses; national parks and forests with boundaries; wildlife preserves; and more!

FreedomMaps come to you preloaded on a single 128 or 256 MB memory card. Insert the memory card into your Lowrance GPS unit, and you're ready to go.

FreedomMaps are available through LEI-Extras. To order a card (or for list of areas available) see ordering information in the back of this manual.

External Antenna

A GPS antenna requires a clear view of the sky for optimum operation. Inside a vehicle, your iFINDER can sometimes maintain satellite lock while sitting on the seat beside you, but we don't recommend this for optimum performance.

Since the view is restricted to what can be seen through the windows, this operating mode will reduce position accuracy and will increase the chance of losing satellite lock. Inside a vehicle, the unit operates best with an optional external antenna mounted on the windshield, on the dash or on top of the vehicle.

The optional external antenna can use a magnetic base that allows temporary mounting on any flat ferrous metal surface. A suction-cup mount allows you to attach the antenna to a windshield.

The iFINDER H2OC can use the passive FA-8 antenna or the active RAA-3 antenna. The active antenna offers a further performance boost by amplifying the satellite signals it receives. This is especially helpful when operating in areas like dense forests, which can obstruct GPS

signals. Your unit will automatically switch between the active RAA-3 and its internal antenna (located in the top of the case). If you purchase the passive FA-8, you must use a menu check box to manually switch between it and the internal antenna. See the topic "External Passive Antenna" in Sec. 5.

Attach the iFINDER antenna to windshield bracket with two screws.

You may achieve good results by placing the external antenna on the top of the dash, at the base of the windshield. A piece of the rubber nonskid shelf liner material available in recreational vehicle supply stores will also help hold the antenna in place.

To use the antenna: Mount it in a location with an unobstructed view of the sky. Plug the connector into the unit's antenna socket, located on the back, in the upper left corner of the case.

R-A-M Bracket Mounting Systems

Several R-A-M mounting brackets are available for your iFINDER. There are permanent mounts and temporary mounts suitable for virtually any boat, aircraft, vehicle, even motorcycle handlebars.

Two R-A-M mounting systems for your unit.

One model has a mounting arm and cradle attached to a swivel ball plate that can be screwed or bolted to a supporting surface. Another has a moldable, weighted, rubber foot and gooseneck for support virtually anywhere without screws or adhesives. R-A-M even has suction cup bases for attachment to windscreens or fiberglass surfaces. See your Lowrance dealer or visit the LEI web site for the latest options. Accessory ordering information is on the inside back cover of this manual. For a complete look at the many mounting options, visit the R-A-M web site at www.ram-mount.com.

Other Accessories

Other iFINDER accessories include MMC cards, MMC card readers and MapCreate™ 6 custom mapping software for your computer. (The iFINDER H2OC Plus model ships with the GPS Accessory Pack, which is composed of the MapCreate CDs, the card reader and one memory card.)

If these accessories are not available from your dealer, see the accessory ordering information on the inside back cover of this manual.

MapCreate™ 6 CD-ROM and MMC card reader for USB ports.

Section 3:

Easy Mode Operation

This section addresses Easy Mode operation for the iFINDER's main GPS functions. The principles are the same in both operating modes, so this discussion also serves as a good introduction to Advanced Mode work.

Before you turn on the iFINDER, it's a good idea to learn about the different keys, the three Page screens and how they all work together. BUT, if you just can't wait to get outside, grab the batteries and turn to the one-page Quick Reference on page 28.

Main Menu

Easy Mode has a single Main Menu, which contains function commands and setup option commands. The tutorial lessons in this section will deal only with functions — the basic commands that make the iFINDER do something. The iFINDER will work fine for these lessons right out of the box with the factory default settings. But, if you want to learn about the various options, see Sec. 5, System Setup and GPS Setup Options.

Main Menu, Easy Mode.

The Main Menu commands and their functions are:

Go To Cursor: navigates to the current cursor position on the map

Cancel Navigation: turns off the navigation command after you have reached your destination.

Screen: changes the contrast or brightness of the display screen and backlight delay.

Sounds: enables or disables the sounds for key strokes and alarms and sets the alarm style.

Navigate Trail: sets up navigation back to the start of the current trail.

Clear Trail: clears all the points stored in the plot trail.

Sun/Moon: finds the rising and setting time of the sun and the moon.

Units of Measure: changes the speed or distance units. Also used to change the heading, time and temperature formats.

Set Local Time: sets the time for your local time zone.

Advanced Mode: used to switch from Easy Mode to Advanced Mode. Easy Mode shows only the most commonly used features to simplify the interface and simplify operation.

Transfer My Data: load or save GPS Data Files containing waypoints, routes, trails and event marker icons.

Software Information: shows the product name and software version of the unit's operating system software, as well as copyright notices.

Pages

Easy Mode has three Page displays that represent the three major operating modes. They are the Satellite Status Page, the Navigation Page and the Map Page. The pages are accessed by pressing the PAGES key. Pressing PAGES repeatedly scrolls among the three screens in an endless loop.

Satellite Status Page

This Page, shown in the following images, provides detailed information on the status of the iFINDER's satellite lock-on and position acquisition. To get to the Satellite Status Page, press PAGES repeatedly until it appears on the screen.

No matter what page you are on, a flashing current position indicator/question mark symbol and flashing GPS data displays indicate satellite lock has been lost and there is no position confirmed. This 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 lock-on with a 3D position acquired.

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. If you hold the unit facing north, you can use it to see which satellites are obstructed by obstacles in your immediate area. 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, which means it isn't being used to resolve the position.

Beneath the circular graph are the bar graphs, one for each satellite in view. Since the unit has 16 channels, it can dedicate one channel per visible satellite. The taller the bar on the graph, the better the unit is receiving signals from the satellite.

The Estimated Position Error (EPE), shown above the bar graphs, 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 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.

Navigation Page

This Page has a compass rose. It shows your direction of travel and the direction to a recalled waypoint. When you're not navigating to a waypoint or destination, the navigation screen looks like the one in the following image. No graphic course information is displayed. Your position is shown by an arrow in the center of the screen. Your trail history, or path you've taken, is illustrated by a 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.
