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.
How this manual can get you out on the water, fast!
Welcome to the exciting world of digital sonar and GPS! We know you're anxious to begin finding fish, but we have a favor to ask. Before you grab the unit and begin installing it, please give us a moment or two to explain how our manual can help you get the best performance from your combination fish finder and GPS receiver. First, we want to thank you for buying a Eagle sonar/GPS unit. Whether you're a first time user or a professional fisherman, you'll discover that your unit is easy to use, yet capable of handling demanding navigation and sonar tasks. Our goal for this book is to get you on the water fast, with a minimum of fuss. Like you, we'd rather spend more time boating or fishing 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 8 sections. This first section is an introduction to the Cuda 240 sonar and GPS. It tells you the basics you need to know before you can make the unit look below the surface to find some fish. Section 2 will help you install your unit, as well as the transducer (the most important part of any sonar installation). We'll also tell you about some of the available accessories. Section 3 covers Basic Sonar Operation. It will show you how easy it is to run your sonar, right out of the box. This section features a one-page Sonar Quick Reference. (If you've already jumped ahead and figured out how to install the unit yourself, and you just can't wait any longer, turn to the Quick Reference on page 37 and head for the water with your unit!) When you come to a sonar menu command on the unit's screen, you can look it up in the manual by skimming over the table of contents, looking it up in the manual's index, just flipping through Section 3 or scanning through the sonar setup options in Section 7. 1

Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult your boat dealer or manufacturer. Other tools are a wooden craft stick or similar tool for stirring and applying epoxy, and a paper plate or piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100 grit sandpaper, specially formulated epoxy adhesive available from LEI (see ordering information on the inside back cover). A sandwich hull also requires polyester resin. Selecting a Transducer Location 1. The location must be in the water at all times, at all operating speeds. 2. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving. 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 10
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 Left, vee pad hull; right, vee hull. 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. Good location
Poor location Good location

TRANSDUCER ORIENTATION AND FISH ARCHES If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds.

Partial fish arches

Transducer aimed too far back
Transducer aimed too far forward
Full fish arch Proper transducer angle Transducer angles and their effects on fish arches.
If the arch slopes up but not back down then the front of the transducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation. SHOOT-THRU-HULL PREPARATION Hulls With Floatation Materials The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area. See the figure below. WARNING: Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications.
Fill with epoxy Flotation material Inner hull

Epoxy to hull first

Outer hull Epoxy the transducer to a solid portion of the hull.
For example, some (but not all) manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fiberglass and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to the outer layer of fiberglass. After the epoxy cures for 24 hours, fill the remaining space with polyester resin. When the job is finished, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. 18

Your sonar unit will work fine right out of the box with the factory default settings. You only need to learn a few basic functions to enhance your viewing. We'll discuss them briefly here, then talk about them and all the other commands in more detail in Sec. 4, Advanced Sonar Operation. Sonar Mode has two primary menus that control its operation. They are the Main Menu and the Sonar Menu. Main Menu The Main Menu contains some basic function commands and some setup option commands. You access the Main Menu by pressing MENU|MENU. You run a command by using or to highlight the command and then pressing ENT. To clear the Main Menu screen and return to the Page display, press EXIT. (Remember, our text style for "MENU|MENU" means "press the Menu key twice." See a full explanation of our instruction text formatting on page 8, Instructions = Menu Sequences.) 32
Main Menu. Main Menu Commands
There are four "basic" Main Menu commands that you'll really want to read more about. They are: Screen commands (CONTRAST, BRIGHTNESS and DISPLAY MODE): change the appearance of the display screen. Use these commands to adjust how the screen looks under various lighting conditions. Sounds command: controls sound levels for keystrokes and alarms. If you don't like to hear a beep each time you press a key, you can turn all sounds off by setting the volume to zero. Sound is especially useful when used with the Fish I.D. fish symbol feature and fish alarm feature. Sonar Alarms command (a sub-menu of Alarms): turns alarms on or off and changes alarm thresholds. The fish alarm, used with Fish I.D., is the most popular use. It tells you when the sonar sees a fish. You can also set deep or shallow depth alarms. Popup Help command (one of the System Setup options): turns the pop-up help boxes on or off. When you select a menu command, these information boxes appear to tell you what the command does or how to use the command. The default setting is on, which is really handy while you're learning. The remaining Main Menu commands are either for GPS use, or for advanced sonar functions, mostly setting various system options. (They're all detailed later in Sec. 4, Advanced Sonar Operation, or Sec. 7, System Setup and GPS Setup Options.) The other Sonar options in the Main Menu are: Set Keel Offset command: calibrates the unit to show depth under the keel or actual depth from the surface. Sonar Simulator command: turns the simulator feature on and off. Useful for learning how to operate the unit and all its functions. Reset Options command: returns all options and auto functions to their original factory settings. It's a great safety net while you're learning and experimenting with various settings. 33

Sonar Operations

As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for how it's working. As you're learning the basics, there is one setting you might want to tinker with from time to time Sensitivity. Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish echoes, if fish are present. As you change the sensitivity setting, you can see the difference on the chart as it scrolls.
Fig. 1 Bait school Fish arches Fig. 2
Thermocline with fish Fig. 3 Fig. 4
These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig. 3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.
You can change the sensitivity level whether you are in Auto Sensitivity mode or Manual Sensitivity mode. The adjustment method works the same in both modes, but it gives you slightly different results. Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on. You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting. In the sonar unit, auto mode will let you increase sensitivity to 100 percent, but the unit will limit your minimum setting. This prevents you from turning sensitivity down too low to allow automatic bottom tracking. When you change the setting with auto turned on, the unit will continue to track the bottom and make minor adjustments to the sensitivity level, with a bias toward the setting you selected. Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control you have complete manual control of the car's speed. In the sonar unit, manual mode allows you to set sensitivity at 100 percent (maximum) or zero percent (minimum.) Depending on water conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 50 percent or less! Try adjusting sensitivity in both auto and manual modes to see how they work. To adjust sensitivity: 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.)

At left, Sonar Page menu with Chart Speed command selected. At right, Chart Speed Control Bar.
If you do experiment with chart speed, remember to reset it to maximum when you resume trolling or moving across the water at higher speed. To change chart speed: 1. From the Sonar Page, press MENU| to CHART SPEED|ENT. 2. The Chart Speed Control Bar appears. Press to decrease chart speed; press to increase chart speed. 3. When it's set at the desired level, press EXIT.

Depth Cursor

The depth cursor consists of a horizontal line with a digital depth box on the right side. The numbers inside the box show the depth of the cursor. 47

Cursor line

Depth box At left, Sonar Page menu with Depth Cursor command selected. At right, sonar chart with the depth cursor active. The line indicates the large fish is 40.53 feet deep.
The cursor can be moved to any location on the screen, letting you pinpoint the depth of a target. 1. From the Sonar Page, press MENU| to DEPTH CURSOR|ENT. 2. The depth cursor appears. Press to lower the cursor line; press to raise the cursor line. 3. To clear the depth cursor, press EXIT.

Depth Range - Automatic

When turned on for the first time, the bottom signal is automatically placed in the lower half of the screen. This is called Auto Ranging and is part of the automatic function. However, depending upon the bottom depth and the current range, you can change the range to a different depth. To do this: 1. From the Sonar Page, press MENU| to DEPTH RANGE|ENT.
At left, Sonar Page menu with Depth Range command selected. At right, the Depth Range Control Scale.
2. The Depth Range Control Scale appears. Press or to select a different depth range. A dark bar highlights the selected range. Range numbers in gray cannot be selected. 3. When the new range is selected, press EXIT to clear the menu.

Depth Range - Manual

You have complete control over the range when the unit is in the manual mode. There are 12 depth ranges, from 5 feet to 800 feet.
To switch to Manual Depth Range:
1. First, turn off automatic depth range. From the Sonar Page, press MENU| to AUTO DEPTH RANGE|ENT. 2. Press to DEPTH RANGE|ENT and the Depth Range Control Scale appears. 3. Press or to select a different depth range. A horizontal dark bar highlights the selected range. 4. When the new range is selected, press EXIT to clear the menu.

Sonar Simulator
This unit has a built-in simulator that lets you run it as if you were on the water. All sonar features and functions are useable. When in simulator mode, you will see [Simulator Mode] in the Sonar Page title bar. To use the simulator: 1. From the Sonar Page, press MENU|MENU| to SONAR SIMULATOR|ENT. 2. Turn off Sonar Simulator by pressing MENU|MENU| to SONAR SIMULATOR|ENT|EXIT. NOTE: If you turn on your unit before attaching a transducer, it may enter a demo mode. The words "demo mode" in a pop-up box flash in the middle of the screen and a sonar chart plays much like the simulator. Unlike the simulator, the demo mode is for demonstration only, and will automatically stop as soon as you turn on the unit with a transducer attached. The simulator will continue to function normally.

Stop Chart

If you are running multiple units on a boat, there are times when you may want to turn off the sonar. This command turns off the sonar and stops the chart from scrolling. Sonar restarts automatically each time you turn on your unit. Press MENU| to STOP CHART|ENT|EXIT. To turn on sonar and start the chart scrolling again, repeat the above step.
Sonar Menu with Stop Chart command selected. The box is unchecked, indicating that the chart is scrolling across the screen.

Surface Clarity

The markings extending downward from the zero line on the chart are called "surface clutter." These markings are caused by wave action, boat wakes, temperature inversion and more. The surface clarity control reduces or eliminates surface clutter signals from the display. It does this by changing the sensitivity of the receiver, decreasing it near the surface and gradually increasing it as the depth increases. There are three levels of surface clarity available: low, medium, or high. It can also be turned off. The default level is off. To adjust the Surface Clarity level: 1. From the Sonar Page, press MENU| to SONAR FEATURES|ENT|ENT.
Sonar Features menu with Surface Clarity selected.
2. Press or to select clarity level|EXIT|EXIT|EXIT. 62

Zoom & Zoom Bar

"Zooming" the display is used to enlarge small detail, fish signals and the bottom with its associated structure. The 2X zoom doubles the size of all echoes on the screen. The 4X zoom quadruples the size of the echoes. You can also turn on a zoom bar on the far right side of the screen; this shows which echoes will be displayed on the screen when the Zoom commands are used. For example, turning on the 2X zoom will show all echoes that are between the top and bottom of the 2X zoom bar. The 4X zoom will show only the echoes between the top and bottom of the 4X zoom bar. To switch the zoom: 1. Press ZIN to increase the zoom display to 2X. Press ZIN again for a 4X zoom. 2. Press ZOUT to reduce the zoom and show more of the chart. To turn on the Zoom Bar: 1. Press MENU| to SONAR FEATURES|ENT. 2. The Sonar Features menu appears. Press to ZOOM BAR|ENT|EXIT|EXIT. 3. To turn off the Zoom Bar, repeat steps 1 and 2.

The arrow in the center of the screen is your present position. It points in the direction you're traveling. The flashing line extending from the back of the arrow is your plot trail, or path you've taken. The plotter's zoom range is the distance across the screen. This number shows in the lower right corner of the screen. In the first example figure below, the range is 4,000 miles from the left edge of the display to the right edge. The Zoom In and Zoom Out keys zoom the plotter to enlarge or reduce its coverage area and the amount of detail shown. There are 39 available zoom ranges, from 0.02 miles to 4,000 miles.
At left, Plotter Page zoomed to 30 miles (note the overlapping, unreadable waypoints) and right, zoomed to 15 miles (with waypoints visible).
The Plotter Page has its own menu, which is used for several functions and for setting various options. To access the Plotter Page Menu, from the Plotter Page, press MENU. The following page contains a 12-step quick reference for the most basic GPS operations. If you don't want to carry the manual with you as you practice with the Cuda 240, you might consider photocopying this quick reference page and tucking it into your pocket.

GPS Quick Reference

Start outdoors, with a clear view of the open sky. As you practice, try navigating to a location at least a few blocks away. While you're learning, navigation in too small an area will constantly trigger arrival alarms. 1. Install the unit. (See complete installation details beginning on page 9.) 2. To turn on the Cuda 240, press and release PWR key. 3. Opening screen displays the GPS plotter at the 4,000 mile zoom range.

IMPORTANT ALARM NOTES: Anchor Alarm - The anchor alarm may be triggered even when you're sitting still. This typically happens when using small (less than 0.05 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.

Auto Satellite Search

To lock onto the satellites, the GPS receiver needs to know its current position, UTC time and date. (Elevation (altitude) is also used in the equation, but it's rarely required to determine a position.) It needs this data so that it can calculate which satellites should be in view. It then searches for only those satellites. When your GPS receiver is turned on for the first time, it doesn't know what your position or elevation (altitude) is. It does know the current UTC time and date since these were programmed into it at the factory and an internal clock keeps the time while the unit is turned off. (If the time and/or date are incorrect, you can set it using the "Set Local Time" menu.) The unit begins searching for the satellites using the above data that it acquired the last time it was turned on. This probably was at the factory. Since it's almost certain that you're not at our factory, it's probably looking for the wrong satellites. If it doesn't find the satellites it's looking for after approximately one minute, it switches to Auto Search. The receiver looks for any satellite in the sky. Due to advanced technology, the auto search time has shrunk significantly from the early days of GPS. Once the unit locks onto the satellites, it should take less than a minute to find your position the next time it's turned on, provided you haven't moved more than approximately 100 miles from the last location it was used. 106

Once you have each field set the way you want, press EXIT repeatedly until you return to the previous page.

Show WAAS Alarm

When the signal is available, your unit will automatically use WAAS to boost the accuracy of the position fix. When the WAAS signal is lost or acquired, an alarm message appears. Since the U.S. government is still developing the WAAS system, it's not unusual for a GPS/WAAS receiver to frequently lose and reacquire its lock on a WAAS satellite. That can result in the alarm repeatedly going on and off. If you want, you have the option of turning off the WAAS Acquired/Lost alarm without affecting how the unit uses WAAS. Here's how: 1. Press MENU|MENU| to GPS SETUP|ENT| to SHOW WAAS ALARM. 2. With the option highlighted, press ENT to uncheck it (turn off) and check it (turn on). After the option is set, press EXIT|EXIT to return to the page display. 3. You can return to this command and press ENT again to turn the feature on.

Addendum I
Additional Instructions for

Eagle Cuda 240i S/GPS

Your sonar/GPS unit, the Cuda 240i, functions exactly like the Cuda 240 described in the manual provided (part 988-0152-012). In addition, the Cuda 240i contains a communications port for NMEA 0183 output. The instructions for connecting data cables and setting up the communications port appear in this addendum.
NMEA 0183 Data Cable Connections
NMEA is a standard communications format for marine electronic equipment. The Cuda 240i can send information to any device that receives NMEA 0183 data. This allows the unit to work with VHF marine radios equipped with the Digital Selective Calling (DSC) distress call feature. To send NMEA 0183 data, the Cuda 240i has one NMEA 0183 version 2.0 communication port. The com port can be used to send NMEA formatted data such as your current position. The provided Cuda 240i data cable plugs into the accessory socket on the right side of the back of your unit's case. The data cable ends in two wires that connect to your VHF radio or other NMEA device. The Cuda 240i uses the yellow wire to transmit and the black shield wire for signal ground. NOTE: Some VHF radios, such as the popular Uniden brand, have input levels which require use of an additional diode and resistor built into the Cuda 240i data cable. This is Wiring Diagram A, which is described on page 2. The majority of the DSC radios will work with the resistor and diode as provided by Eagle. 1
A few other radio brands (and other electronic devices) that meet the NMEA 0183 standard won't need these adapters and you will have to remove the resistor and diode to make those work. This is Wiring Diagram B, which is described on page 4. Consult your other device's owners manual, then read through all of the following instructions before you begin. Use the installation diagram most suited to your brand of radio or other device. If your device manual indicates an RS-232 connection (i.e., a computer), remove the resistor and diode and connect using Wiring Diagram B. Most other connection types (TTL; NMEA + and NMEA ; differential) will require Wiring Diagram A.
Recommended Tools and supplies
Recommended tools for this job include: wire pliers or wire stripper and a wire cutter. Required supplies for this job include: two gray (18 gauge) or blue (16 gauge) wire nuts and electrical tape. Supplies are not included.
Wiring Diagram "A"
Begin by stripping the wire ends of the device you're connecting to the Cuda 240i. (You'll notice the Cuda 240i's data cable comes pre-stripped, with wire ends exposed.) Use a pair of wire pliers to strip about 1/4-inch (6.35 mm) of insulation from each of the radio's or other device's data wires.
Strip the ends of the VHF radio's data wires. Connect them to the prestripped wires of the Cuda 240i's data cable (shown right).
Twist the exposed wires together as shown in the following figures. If you're using a Uniden or similar radio, connect the radio's NMEA Wire to the Cuda 240i data cable's yellow wire, and the radio's Ground/Shield wire to the Cuda 240i data cable's black shield wire. If you're using another radio brand or NMEA device, see Wiring Diagram B instructions at the end of page 3.

Twist the appropriate wires together, making sure that the exposed ends make good contact. Secure the wire ends with wire nuts, then wrap each wire nut securely with electrical tape to protect against moisture, as shown in the figure on the right.
After taping the wire ends individually, wrap the entire connection with electrical tape as shown. This will help protect from moisture and prevent the wires from breaking contact. Wiring Diagram "B"
If your VHF radio or other device requires true RS-232, you will need to remove the diode and resistor built into the end of the Cuda 240i data cable. You will notice near the end of the cable a segment protected with black heat-shrink. To connect the Cuda 240i to a true RS-232 radio, first remove the Uniden adapter segment of the cable as shown in the following figures.
For Wiring Diagram B installations, remove the Uniden adapter segment at the end of your data cable as shown at left. Snip off the end of the cable protected by the black heat-shrink. At right, we have used clear heat-shrink for clarity, so you can see the diode and resistor protected within. Remove this portion of the cable.
After you've removed the adapter segment, use wire pliers to expose the ends of the five remaining wires in the cable. Cut off the black, blue and white wires, then seal their ends with electrical tape.
Black Blue White Cut black, blue and white.

Bare wire (shield)

Yellow (transmit)
After removing the adapter segment, prepare to connect by removing and taping off unneeded wires. Strip the end of the yellow wire.
Strip about 1/4-inch (6.35 mm) of insulation from the yellow wire, then follow the preceding wire nut and taping instructions to connect the wires from the radio or other device. If you're using a true RS-232 radio or other device, connect its (+) Receive wire to the Cuda 240i data cable's yellow wire and its ground or () Receive wire to the Cuda 240i data cable's bare shield wire.

Once in the Communication Ports menu, you can configure the unit to use specific NMEA sentences. (The default setting has all NMEA sentences turned on.) Press to CONFIGURE NMEA|ENT.
NMEA Sentences selection menu.
A menu appears showing the prefixes of the available NMEA sentences. A check mark next to a prefix means the prefix is in use. Use to select a prefix, then press ENT to turn off the prefix. (Press ENT again to check the box and turn a prefix on.) NOTE: The names of the NMEA sentences are abbreviated in this menu. These are the functions of the various selectable prefixes: GLL transmits latitude and longitude of present position, time of position fix, and status. 7

GGA transmits time, position and fix related data. APB transmits autopilot information. RMC and RMB transmits navigation information messages. GSA and GSV transmits fix mode, DOP values and satellites in view information. DBT transmits the depth below the transducer. DPT transmits the depth MTW transmits the water temperature.
4. When the desired prefixes are checked or unchecked, press EXIT|EXIT|EXIT|EXIT to return to the previous page.
Compatibility With Various VHF Radios
The Digital Selective Calling (DSC) feature in marine radios is relatively new technology. The U.S. Coast Guard, for example, implemented its first DSC-capable systems in Atlantic City, N.J. and Chincoteague, VA in September, 2003. However, the entire U.S. DSC rescue system won't be operational until Sept. 30, 2006. As more marine electronics manufacturers enter this growing market, other connectivity issues with your unit may appear. You can check for known compatibility issues by visiting our web site, www.eaglesonar.com. Look in the Manuals section for updated documents for your sonar/GPS unit.
