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.

When navigating to a waypoint or following a route, the Navigation screen looks like the one shown in the next image. The cross track error range white corridor is 0. The driver is headed toward the cursor location, which is 0. Page 33 Map Page opening screen left ; Map zoomed to miles center ; Map zoomed to 6 miles right.
Over Zoomed means you have reached the detail limits in an area covered only by the basic background map. Zooming in any closer will reveal no more map details because a high- detail custom map for this area has not been loaded on the MMC. Page 34 What's more important is the large-scale map detail that allows your GPS unit to show a higher level of position accuracy. For example, the background map would show you the general outline and approximate shape of a coastline or water body, but the higher detail in MapCreate shows the shoreline completely and accurately finer detail.
Even though their display is turned off, you can still search for POIs and their icons will pop-up when the unit finds them. The following page contains a step quick reference for Easy Mode operation. As you practice, try navigating to a location a few blocks away. Navigation in too small a space, like a backyard, will constantly trigger arrival alarms. Clouds do not restrict GPS signal reception.
If satellite acquisition takes longer than usual, 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 has as clear a view of the sky as possible, then turn the unit off and back on again. Searching is one of the most powerful fea- tures 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. A list of restaurants will appear with the closest at the top of the list and the one furthest from you at the bottom of the list.
The location nearest you will be highlighted. To clear the search and return to the main page display, press repeatedly. Before you exited out of the Search menus, you could have gone looking for another place. If you have not loaded a high-detailed custom map covering the desired search area, you may not find much. If the cursor was not active, the point would be placed at the current position. Caution: Saving a new Home waypoint will overwrite and erase the pre- vious Home waypoint.
Go Home This command will automatically take you back to the Home waypoint you created. It is a quick and handy way to navigate to anything you can see on the map display. Page Navigate To A Point Of Interest The mile zoom figure left shows the course line connecting your current position to your destination. The mile zoom center shows both current position and destination on screen. The Navigation Page right will also show navigation information.
The trail is saved in memory when the unit is turned off. The iFINDER continues recording the same trail until you clear the trail, which erases the old trail and begins recording a new trail. Page 45 NOTE: If you are already located at or near the beginning of your back trail, the arrival alarm will go off as soon as you hit Enter.
Just press to clear the alarm and proceed. EXIT On the map, your original trail is visible as a solid line, along with a roughly parallel dotted line indicating the back trail to follow.

Create a Waypoint by Projecting a Position This feature sets a waypoint at a location a specific distance and bear- ing from a reference position. The reference position can be a highway exit, a map place or an item from your waypoints list. Waypoint Audio Note Audio notes are most helpful when you only have time to quick save a waypoint and move on. After saving the waypoint, you can record an audio note, giving specific information related to the waypoint that would have otherwise, been undocumented.

You can set an arrival alarm to flash a warning message and sound a tone when you cross a preset distance from a waypoint. Page Auto Satellite Search It then searches for only those satellites.
When your GPS receiver is turned on for the first time, it does not know what your position or elevation altitude is. The unit begins searching for the satellites using data acquired the last time it was turned on. The Com Port Menu, accessed from the System Setup Menu in Advanced Mode, allows you to configure the communi- cations port to send data to another electronic device, like autopilot. To set Com Port Configuration: 1. To determine the accuracy in your area, place yourself in a known location and turn on the GPS.

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 GPSequipped vehicle fails to pay full attention to travel conditions and vehicle operation while the vehicle is in motion.
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. 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. 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 one-page 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. 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, 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.
This section covers both Easy Mode and Advanced Mode options. 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! Finally, in Section 7, we offer Supplemental Material , including a list of the GPS datums used, warranties, and customer service information. Now, if you are into the fine details, glance over the next segment on specifications to see how much GPS power you hold in your hand.
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. If you're new to GPS, read on, and you can later impress your friends with your new-found knowledge. But don't worry — we made it easy to use, so you don't need to be a computer expert to find your way! This pocket-sized unit also contains an antenna and specialized scanning receiver, similar to a car radio.
But instead of your favorite dance tunes, this receiver tunes in a couple of dozen GPS satellites circling the earth. 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. We lock it in at the factory — you can't change or close this map. 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. These solid-state memory devices are about the size of a postage stamp, but can hold data ranging from 8 MB to 1 GB.
Compare that to a floppy disk's 1. Or store them on a pocketful of MMCs, if you don't have a computer. These MapCreate custom maps contain much greater detail than the basic background map. These custom maps are preloaded on MMCs. No computer work required! To use a custom map, all you need to do is slide an MMC containing a map into the unit. 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.
It was designed as a hour-a-day, days-a-year, all-weather global navigation system for the armed forces of the U. 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, , after the military developed other methods to deny GPS service to enemy forces.
Reliable accuracy for civilian users jumped from meters feet under SA to the present level of 10 to 20 meters about 30 to 60 feet. Twenty-four satellites orbit 10, 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. 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. 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. There will be more "wandering" of the data shown on the display. GPS alone is plenty accurate for route navigation, but the U.
The FAA commissioned the system on July 11, It does this by broadcasting correction signals on GPS frequencies.
There, however, are some fringe areas of the U. 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.
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. 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:. The arrow keys control the movement of dotted crosshairs lines the cursor on your mapping screen.
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. These indicate that you are to select this command or option from a menu or take an action of. Text that you may need to enter or file names you need to select are shown in italic type, such as trail name.
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:. Translated into complete English, step 1 means: "Press the Menu key. Use the down arrow key to scroll down and select highlight the Navigate Trail command. Press the Enter key. 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. The unit requires two, 1. We recommend you use alkaline batteries for the best trade-off between battery life and cost. 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.
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. 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. 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. 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. 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. Do not remove the cigarette lighter adapter and splice the exposed wires directly to a 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 volt power source will destroy the unit. This damage will not be covered by your warranty.
These cables are discussed in the following segment on NMEA 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 data. It has a standard female DB-9 connector on one end to attach your unit to a computer's serial communications port.
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. Both of these solid-state flash memory devices are about the size of a postage stamp. 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. Remove battery compartment cover. Remove batteries, if present. Hold unit facedown in right hand. Use your thumb or index finger and press down on the center of the MMC label. Drag the MMC from the slot into the battery compartment. Drop the MMC card into the slot, label-up, with the notched edge toward the right.
Press down on the center of the label and slide the card to the right. Turn the plastic rotating card lock until it holds the card firmly in place with the grip parallel to the direction of the batteries. Replace the batteries and battery cover.

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 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. 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 non-skid 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. There are permanent mounts and temporary mounts suitable for virtually any boat, aircraft, vehicle, even motorcycle handlebars. 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.
If these accessories are not available from your dealer, see the accessory ordering information on the inside back cover of this manual. 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 Satellite, Navigation, Compass and Map.
Each page represents one of the unit's major operation modes. MENU — Press this key to show the menus, which allow you to select or adjust a feature from a list. ENT — The enter key allows you to save data, accept values or execute menu commands.
Less detail is seen as you zoom out. ZIN — Zoom In — This key lets you zoom in the screen to see greater detail in a smaller geographic area on the map. To turn on the unit, press PWR.
To turn on the backlight, press PWR again. Pressing PWR again will turn off the backlight. Press EXIT to message or alarm displays. Turn off the unit by pressing and holding the PWR key for 3 seconds. Easy Mode has a single Main Menu, which contains function and setup option commands.
The lessons in this section will deal only with functions. But, if you want to learn about the various options, see Sec. 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. Set Local Time : sets the time for your local time zone. Easy Mode shows only the most commonly used features to simplify the interface and simplify operation.
Software Information : shows the product name and software version of the unit's operating system software, as well as copyright notices. Easy Mode has a three page display. The Satellite Status page, shown in the following images, provides detailed information on the status of the iFINDER's satellite lock-on and position acquisition. This page shows you the quality and accuracy of the current satellite lock-on and position calculation. 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. 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.
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. If the position error flashes dashes, then the unit hasn't locked onto the satellites and the number shown isn't valid.
At the center of the Navigation Page is a compass rose. It shows 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. 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 highlights your current track direction of travel.
When navigating to a waypoint or following a route, the Navigation screen looks like the one shown in the next image. Your ground speed, track, distance, course and bearing to a waypoint, all can be shown digitally on this screen. The current cross-track error is shown in the XTK box. This is the distance you are off-course to the side of the desired course line. The course line is an imaginary line drawn from your position when you started navigating to the destination waypoint.
It's shown on the navigation page as a vertical dotted line. Lines on either side of the present position show the current cross track error range. The default for the cross track error range is 0. For example, if the present position symbol touches the right cross-track error line, then you are 0. You need to steer left to return to the desired course. A circular symbol illustrating your destination waypoint appears on the screen as you approach the waypoint.
Travel Time is the time it will take to reach a destination at the present closing speed. Arrival Time is the local time it will be when you arrive at the destination, based upon the present closing speed and track. Bearing Waypoint arrow symbol. Navigation Page, going to cursor.
The cross track error range white corridor is 0. The driver is headed toward the cursor location, which is 0. The vehicle is basically on course off course only 1 foot. Traveling at 34 mph. The driver will arrive at the waypoint in 18 seconds.
The map 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 using options in Advanced Mode. See the topic Map Orientation , in Sec. If you're navigating to a waypoint, the map also shows your starting location, present position, course line and destination.
When our text says, navigating to a waypoint, it is synonymous with navigation to any selected item, whether it is a waypoint you made, a map feature or an item from the POI database. A screen similar to those in the following images will appear. The arrow flashing in the center of the screen is your present position.
It points in the direction you're traveling. The solid line extending from the arrow is your plot trail or path you've taken. The zoom range is the distance across the map. This number is shown in the lower left corner of the screen.
