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 way- point, but will also visually check to make sure a clear, safe path to the waypoin

Section 1: Read Me First! How this manual can get you out on the road, fast! Welcome to the exciting world of digital sonar and GPS! We know you're anxious to begin navigating and 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 compact, wide-screen, combination fish finder and mapping GPS receiver. First, we want to thank you for buying a Lowrance s

After you've gained some experience with your sonar, you'll want to check out Section 4, which discusses more advanced Sonar Options and Other Features. When you come to a sonar menu command on your unit’s screen, you can look it up in the manual by skimming over the table of contents, just flip- ping through Section 3 or scanning through the sonar options in Section 4. If you're having difficulty with your sonar, you can find an answer to the most common problems in Section 5, Sonar Troubleshoo

(Lowrance developed the world's first transistorized sportfishing sonar in 1957.) A sonar consists of a transmitter, transducer, receiver and display. In simple terms, here's how it finds the bottom, or the fish: The transmitter emits an electrical impulse, which the transducer con- verts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object (fish, structure, bottom) and bounces back to the transducer, which converts

as many satellites as it can "see" above the horizon, eliminates the weakest signals, then computes its location in relation to those satel- lites. Once the unit figures its latitude and longitude, it plots that posi- tion 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 each unit is a basic background map of the entire world. We lock it in here at the factory — you can't change or e

ate software. These MapCreate custom maps contain much greater de- tail than the basic background map. These Custom Map Files (file format *.lcm) not only may be shared between the LMS-334c iGPS and 339cDF iGPS, but also with other Lowrance GPS and sonar/GPS units as well as personal computers. (For example, the exact same MMC, custom map files and GPS data files can be used interchangeably be- tween your gimbal-mounted unit and the hand-held iFINDER GPS receiver.) Your unit automatically read

Three of these satellites are spares, unused until needed. The rest vir- tually guarantee that at least four satellites are in view nearly any- where 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. A minimum of three satellites are required to determine a 2D fix

this by broadcasting correction signals on GPS frequencies. Your unit automatically receives both GPS and WAAS signals. However, there 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

Sonar Viewer You can also download a free copy of our Sonar Viewer software. This PC-based software application plays back any sonar chart log recorded with a Lowrance sonar product. Features include: • Adjustable range, zoom, sensitivity, ColorLine, noise rejection, surface clarity, etc. • Color interpretation of sonar signals can be user defined. • Operates like a Windows Multimedia Player with forward, re- verse, pause, fast forward, fast reverse, and scroll buttons. • Adjustments update the

Arrow Keys The arrow keys control the movement of dotted cross-hair lines on your mapping screen called the cursor. The arrow keys also control a hori- zontal line depth cursor on the sonar screen. The arrow keys help you move around the 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.
