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

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, flipping 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 Troubleshooting. The manual switches from sonar to navigation in Section 6, which introduces you to Basic GPS Operations. This section features a one- page GPS Quick Refer

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 11. If you're new to GPS, read on, and you can later impress your friends with your new-found knowledge.) First, think of your unit as a small but powerful computer. (But don'

erase 'em and record new ones, over and over again. Like any computer file, these GPS Data Files (file format *.usr) can be shared between other Lowrance GPS or sonar/GPS units and even personal computers. Your unit has one more thing in common with a personal computer. Just as computers have a floppy disk drive for storing and exchanging files, this unit has a slot for an MMC (MultiMedia Card) or SDC (Secure Digital card) flash memory card. These solid-state memory devices are about the size of

The Global Positioning System (GPS) was launched July 17, 1995 by the United States Department of Defense. 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

Like most GPS receivers, this unit doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the satellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for the unit to determine direction of travel, you must be moving and the faster, the better. This is not to say that it won’t work at walking or trolling speeds — it will. There will simply be more "wandering" of th

How to use this manual: typographical conventions Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type, so you can easily skim the instructions and pick out what menu command to use. 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 horizontal line depth cursor on the sonar screen. The arrow keys also help you move around the menus so you can execut

Section 2: Installation & Accessories Preparations You can install the sonar and GPS systems in some other order if you prefer, but we recommend this installation sequence: CAUTION: You should read over this entire installation section before drilling any holes in your vehicle or vessel! 1. Determine the approximate location for the sonar/GPS unit, so you can plan how and where to route the cables for the antenna, transducer and power. This will help you make sure you have enough cable length fo

Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once the epoxy is applied and it is set into position, the transducer cannot be removed. Remember, the transducer installation is the most critical part of a sonar installation. Recommended Tools and supplies If you prefer the option of routing the cable through the transom, you will need a 1"
