How Your Sonar Works

Sonar has been around since the 1940s, so if you already know how it works, skip down to read about the relatively new technology of GPS. But, if you've never owned a sonar fish finder, this segment will tell you the underwater basics. Sonar is an abbreviation for SOund NAvigation and Ranging, a technology developed during World War II for tracking enemy submarines. (Lowrance developed the world's first transistorized sportfishing sonar in 1957.) A sonar consists of a transmitter, transducer, receiver and display. Heres a simple explanation of how it finds the bottom and the fish. The transmitter emits an electrical impulse, which the transducer converts into a sound wave and sends into the water. (Humans or fish can't hear the sound frequency.) The sound wave strikes an object (fish, structure or bottom) and bounces back to the transducer, which converts the sound back into an electrical signal. The receiver amplifies this return signal, or echo, and sends it to the display, where an image of the object appears on the scrolling sonar chart. The sonar's microprocessor calculates the time lapse between the transmitted signal and echo return to determine the distance to the object. The whole process repeats itself several times each second. Your sonar unit can record a log of the sonar signals that scroll across the screen and save them to the MMC memory card. (These recordings are also called sonar charts or sonar graphs.) You can replay this sonar log in the unit using the Sonar Simulator function, or play it back on a personal computer using our free Sonar Viewer. The viewer is available for download from the Lowrance web site, www.lowrance.com. You can save several different sonar log files, erase them and record new ones, over and over again. The size of your sonar recordings are only limited by the free space available on your MMC.

How Your GPS Works

You'll navigate faster and easier if you understand how this unit scans the sky to tell you where you are on the earth and, where you're going. (But if you already have a working understanding of GPS receivers and the GPS navigation system, skip on ahead to Section 2, Installation & Accessories on page 9. If you're new to GPS, read on, and you can later impress your friends with your newfound knowledge.) First, think of your unit as a small but powerful computer. (But don't worry we made the series easy to use, so you don't need to be a computer expert to find your way!) The unit includes a keypad and a screen with menus so you can tell it what to do. The screen also lets the unit show your location on a moving map, as well as point the way to your destination. This gimbal-mounted unit uses an external antenna/receiver module, which makes the whole system work something like your car radio. However, instead of your favorite dance tunes, this receiver tunes in to a dozen GPS satellites circling the earth. (It will also listen in to the WAAS satellites in orbit, but more about that in the upcoming segment introducing you to GPS and WAAS.) Your unit listens to signals from as many satellites as it can "see" above the horizon, eliminates the weakest signals, then computes its location in relation to those satellites. Once it figures its latitude and longitude, the unit plots that position on the moving map shown on the screen. The whole process takes place several times a second! The performance doesn't stop there. Stored in the permanent memory of every unit is a basic background map of the entire world. We lock it in here at the factory you can't change or erase this map. The background map is suitable for many navigation chores, but for maximum accuracy and much more detail, you need our optional mapmaking software, MapCreate. Some unit features such as searching for businesses and addresses won't work without a custom MapCreate map. There is so much detail in our background map (and even more in MapCreate) that we'll describe their contents and differences in Section 6, Basic GPS Operations, on page 99. NOTE: The LCX-28CHD, LCX-38 CHD and LCX-113CHD have NauticPath charts, Fishing Hot Spots Elite charts and all high detail custom maps preloaded onto a 30-Gigabyte hard drive. Therefore, if you own either the LCX-28CHD or the LCX-113CHD, you do not need to load any of those charts/maps into the unit. The unit can also use Navionics charts, but they must be loaded into the unit via a Navionics card. MMC and SD cards still will be necessary to log sonar chart data and to store GPS data files. 4

Well, now you know the basics of how the unit does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page 9, so you can mount your unit and plug in the power. 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 7. But, if you want to understand the current state of satellite 5
navigation, look over this segment describing how GPS and its new companion WAAS work together to get you where you're going. The United States Department of Defense launched Global Positioning System (GPS) on July 17, 1995. 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, 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 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. Trees, buildings, an automobile roof, even your body can easily block these signals.

Good location Stern view showing good location for mounting sensor on transom.

Transom

Bottom of hull Speed sensor mounting configuration: side view (left) and rear view (right.)
If the base of the transom has a radius, fill the gap between the transom and the sensor with the sealant. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 7/8". CAUTION: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the screws. The sensor is now ready for use. Connect the sensor to the sonar socket on the back of your unit and connect the transducer to the speed sensor's socket. If you have any questions concerning the installation of the sensor, please contact your local boat dealer.
GPS Antenna/Receiver Module
The LCX-27C, LCX-28C HD, LCX-37C, LCX-38 C HD, LCX-112C and LCX113C HD packages include the LGC-3000 GPS module. This device contains the unit's external antenna and receiver for GPS and WAAS signals. The antenna/receiver module comes with a 15-foot extension cable. This module can be mounted on a flat surface or pole, or an optional magnet is available for temporary mounting on any ferrous surface.
LGC-3000 Module, bottom view (left) and top view (right).
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, connect it to the unit. The LGC-3000 can communicate with your GPS unit either directly (using the supplied extension cable) or through a NMEA 2000 network. NOTE: See the modules instruction sheet, publication part number 9880154-651, for complete installation instructions. In an automobile, you may achieve good results by simply 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 help hold the antenna in place. This may not work well if you have a cab-over design pickup truck camper or motor home. If dashboard reception is poor, simply relocate the antenna module elsewhere on the vehicle for a clearer view of the sky.

Section 3: Basic Sonar Operation
This section addresses the unit's most basic sonar operations. The instructions presented in Sec. 3 follow a chronological order. Sec. 4, Sonar Options & Other Features, will discuss other more advanced functions and utilities. Material in Sec. 4 is arranged in alphabetical order. Before you turn on the unit, it's a good idea to learn about the different keys, the Main Menu, the four Page screens and how they all work together. BUT, if you just can't wait to get on the water, turn to the one-page Quick Reference on page 55.

Colorline

Colorline lets you distinguish between strong and weak echoes. It "paints" a brighter color on targets that return a stronger signal. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddy or weedy bottom returns a weaker signal, which is shown with a narrow, colored line (dark blue tinged with red or a little yellow.) Since fish are among the weakest echoes, they show up 65
mostly as blue arches. A hard bottom or other relatively hard target returns a strong signal displayed as a wide, brightly colored line (reddish yellow to bright yellow.) If you have two signals of equal size, one with red to yellow color and the other without, then the target with brighter color (yellow) is the stronger signal. This helps distinguish weeds from trees on the bottom, or fish from structure. Colorline is adjustable. Experiment with your unit to find the Colorline setting that's best for you.

To return to the main sonar display, press ENT repeatedly. For advanced information on Overlay Data Style, skip ahead to 163.
Ping Speed & HyperScroll
Ping Speed controls the rate at which the transmitter and transducer broadcast sonar sound waves pings into the water. The unit has a default ping speed of 50 percent. At normal boating speeds, this automatically provides enough return echoes to refresh the screen and scroll the chart at maximum chart speed. However, when you are running at high speeds, or just want the fastest possible screen update, you may want to use the HyperScroll feature. When you change the Ping Speed to any setting greater than 50 percent, the unit automatically enters HyperScroll mode. These faster ping rates allow you to maintain a high-detail picture on the screen, and the screen refresh rate and chart scroll speed can keep pace with the boat as it moves quickly over the bottom terrain. When using HyperScroll, you may also need to manually decrease the sensitivity for optimum performance. Depending on water depth and other conditions, HyperScroll may cause a second bottom echo to return to the transducer during the next ping cycle, or sounding. This can result 82
in a large amount of clutter appearing on the screen. If this occurs, just decrease the sensitivity to a level that eliminates the clutter. When you turn HyperScroll off, you can return to your original sensitivity level.

To change Ping Speed: 1. From the Sonar Page, press MENU| to PING SPEED|ENT. 2. The Ping Speed Control Bar appears. Press to increase ping speed; press to decrease ping speed. When it's set at the desired level, press EXIT. To turn off HyperScroll: 1. From the Sonar Page, press MENU| to PING SPEED|ENT. 2. The Ping Speed Control Bar appears. Press to decrease ping speed to 50 percent. When it's set at the desired level, press EXIT. When you boost ping speed and switch into HyperScroll, the width of the FasTrack bar graph display doubles at the right side of the screen. This allows you to see the virtually instantaneous sonar returns better, just as you would on a flasher sonar unit. For more information on FasTrack, see its entry in this section.
