INTRODUCTION > CAUTION

Caution

Failure to avoid the following potentially hazardous situations may result in injury or property damage. The GPSMAP 278 is designed to provide you with route suggestions. It does not reect road closures or road conditions, trafc congestion, weather conditions, or other factors that may affect safety or timing while driving. Use the GPSMAP 278 only as a navigational aid. Do not attempt to use the GPSMAP 278 for any purpose requiring precise measurement of direction, distance, location, or topography. The Global Positioning System (GPS) is operated by the United States government, which is solely responsible for its accuracy and maintenance. The governments system is subject to changes which could affect the accuracy and performance of all GPS equipment, including the GPSMAP 278. Although the GPSMAP 278 is a precision navigation device, any navigation device can be misused or misinterpreted and, therefore, become unsafe.
Map Data Information: One of the goals of Garmin is to provide customers with the most complete and accurate cartography that is available to us at a reasonable cost. We use a combination of governmental and private data sources, which we identify in product literature and copyright messages displayed to the consumer. Virtually all data sources contain inaccurate or incomplete data to some extent. In some countries, complete and accurate map information is either not available or is prohibitively expensive.

GPS Tips

While the receiver is gathering information, your location on the map might appear different from where you are actually located. As soon as the receiver gathers enough satellite information, your proper location appears on the map. When you travel more than 600 miles with the GPS receiver turned off, the receiver may take longer than normal to initialize and nd your location. The GPS receiver can lose satellite signals due to interference from such items as buildings, tunnels, and heavy tree cover. Monitoring the GPS status is recommended.
Start/Stop Simulatorstart and stop Simulator Mode, which is helpful when learning how to use your unit. Enable/Disable EGNOSenable or disable EGNOS capability.

SETTING UP AND USING SONAR > SETTING UP SONAR

Setting Up Sonar

Use the Sonar tab on the Main Menu to set up the Sonar Page.
Depth Numberselect how efcient the digital depth update rate is. Fast Update updates quicker and is recommended for low-noise water deeper than 50 feet. Auto is best for shallow water or highnoise areas, has a slower screen update, and is best used if you travel a wide variety of depths. If the unit is unable to track the bottom for any reason, the digits in the depth window ash on and off to alert you that the unit is not tracking the bottom.
Fish Symbolsselect how the Sonar Page shows underwater targets and background information. Select Off to show all of the available information about the underwater environment. Select a sh symbol, to show only the information related to that symbol. Water Typeselect the proper water type you are boating in. Because sound waves travel through fresh and salt water at different rates, it is necessary to select the water type to ensure accurate readings on the unit.

Understanding the Sonar Display
One of the rst things to understand about sonar is that the transducer sends a beam down to the bottom of the water, much like the beam of a ashlight. The beam starts small near your vessel and expands as it gets to the bottom. See Transducer Coverage for more detailed information. The Sonar Page does not show a three-dimensional representation of the underwater environment; the display is in two-dimensions, much like if you took a picture of an aquarium. Only the depth of the item in the water appears. The Sonar display does not show you where an item is located horizontally in the water, as shown in the drawings below. The sh is not directly above the tree in reality, but it might look like it is on the Sonar Page.

Fish Sonar Page

Generally speaking, if the only thing between the transducer and the bottom is water, the rst strong return comes from the bottom directly below the transducer and sets the bottom level. Weaker secondary returns provide the detailed data. Stronger returns appear in darker colors, with red being the strongest return.

Aerial View of the Water

Transducer Coverage

The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. The wide Coverage cone angles (40) associated with low frequencies (50 kHz) provide Diameter a large coverage area for nding sh within a coverage width that is approximately 2/3 of the water depth. However, this also means that wide cone angles produce less bottom detail and resolution. As shown in the drawing on the near right, the 40 cone angle produces a coverage area of approximately a 20-foot diameter circle at a 30-foot depth. The narrow cone angles (10) associated with high frequencies (200 kHz) provide better bottom resolution and crisper detail, but cannot show a large coverage area for nding sh. The 10 cone angle provides a coverage width that is approximately 2/10 of the water depth. As shown in the drawing on the far right, the 10 cone angle produces a coverage area of approximately a 6-foot diameter circle at a 30-foot depth. Dual frequency mode combines both frequencies to get the best coverage area and contour/depth readings.

Depth Coverage Diameter

40 Cone Angle (50 kHz)

10 Cone Angle (200 kHz)

Whiteline
The GSD 20 or GSD 21 can help you determine whether the bottom is hard or soft. When the sonar sound waves are reected back by the bottom, a hard bottom returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom, while a thick whiteline indicates a harder bottom. Normally, a red line is used to show the point where water meets the bottom. This line follows the bottom contour, along with any signicant objects lying on the bottom. The unit uses the whiteline function to make the bottom layer information easier to distinguish.

Thermoclines

A rough denition of a thermocline is a break in water where the water temperature changes faster than the water above it. Thermoclines are shown as the weakest colors. One of the unique features offered by Garmin is See-Thru technology, which allows the GPSMAP 278 to hear both weak and strong signals simultaneously so it can identify sh returns under the toughest conditions, such as suspended in thermoclines or even hiding near structures. See-Thru technology allows the GSD 21 or GSD 20 Sounder Modules to see through thermoclines and helps locate sh where they live.

APPENDIX > WHAT IS EGNOS/WAAS/MSAS AND LORAN TD SETUP

What is EGNOS/WAAS/MSAS?

The European Geostationary Navigation Overlay System (EGNOS) is European Space Agency developed service to improve the overall integrity of the GPS signal and increase position accuracy for users in Europe. In North America, EGNOS is referred to as WAAS. The system is made up of satellites and network of ground reference stations positioned across Europe that monitor GPS satellite data. All SBAS systems use the same receiver frequency; therefore any operational SBAS system should be capable of providing your GPS unit with increased accuracy at any location in the world. Currently, enabling EGNOS/WAAS on your Garmin GPSMAP 278 in regions that are not supported by ground stations may not improve accuracy, even when receiving signals from an SBAS satellite. In fact, it can degrade the accuracy to less than that provided by GPS satellites alone. For this reason, when you enable EGNOS/WAAS on your Garmin GPS receiver, the receiver automatically uses the method that achieves the best accuracy. To enable EGNOS/WAAS, see to page 6.

To add a new Directory entry:
1. Open the DSC Directory on the Main Menu. 2. Use the ROCKER to highlight the rst blank space in the directory list and press ENTER. OR Press MENU, highlight New Item, and press ENTER. 3. Enter the MMSI number, the name, and any comments. 4. When nished, highlight OK, and press ENTER.

Setting Up DSC

Highlight OK and press ENTER to save the directory entry. New Directory Item Page
Use the Setup sub tab to turn DSC on and off. If you have more than one chartplotter and only want DSC to display on another chartplotter, turn DSC off on this unit. This Setup sub tab also allows you to simulate Distress Calls and Position Reports while the unit is in Simulator Mode. Simulating calls is helpful for practice before connecting to the real system. The Distress Call simulator also helps to check if alarms are working properly.
After creating a New Directory Item, the name created is attached to that particular MMSI number. If you return to the Log, the new name appears under the corresponding MMSI number. Another way to input a name is from the Entry Review Page or the DSC Distress Call or DSC Position Report pages. The Name and MMSI are sent to other Garmin GPS units: Only the MMSI numbers are sent to other non-Garmin DSC users.

Making a Distress Call

To make a Distress Call, press the MayDay button on your VHF radio. The call transmits on an emergency channel with the MMSI number attached to the call, if you have DSC support. Any DSCequipped mariner (on sea or land) within range can receive the call.

DSC Setup

What is a Maritime Mobile Service Identity (MMSI) Number?
MMSI allows a VHF radio to act like a phone. The 9-digit MMSI number acts like a phone number when used in a position report and as a unique identier to the Coast Guard when used in an emergency distress call. To obtain a MMSI number, users must register their VHF radio with the FCC (Form 605). Garmin does not supply this number! For more information regarding MMSI numbers, visit www.navcen.uscg.gov/marcomms/gmdss/mmsi.htm.
Non-Federal Users in the United States Commercial users, or those who travel outside the United States or Canada, must apply for a ship station license or an amendment to a ship station license. To nd out if you require a Ship Station license, visit http://wireless.fcc.gov/marine/fctsht14.html. If your vessel requires licensing by the FCC, you can obtain a MMSI during the application/licensing process when you le FCC Forms 159 and 605. Federal Users in the United States Federal users can obtain MMSI assignments from their agency radio spectrum management ofce. These procedures are currently under review by the National Telecommunications and Information Administration (NTIA). Users Outside the United States Users can obtain an MMSI assignment from their telecommunications authority or ship registry, often by obtaining or amending their ship station license.
