Languages....................... 10; menu languages selectable by user. MMC slots: ...................... One with waterproof door (SD card compatible). Sonar Frequency....................... 50/200 kHz for SeaCharter 642cDF iGPS; 200 kHz for FishElite 642c iGPS. Recording:........................MMC & SD cards for recording sonar chart logs. Transducers: .................. A dual-frequency Skimmer. transducer with built-in temperature sensor is packed with the SeaCharter 642cDF iGPS. It has 35°/12° cone angles. A single-frequency Skimmer transducer with built-in temperature sensor is packed with the FishElite 642c iGPS. It has a 20° cone angle. Transducers operate at speeds up to 70 mph (61 kts) Watts: ............................... SeaCharter 642cDF iGPS: 4,000 watts peak-to-peak/500watts RMS. FishElite 642c iGPS: 1,500 watts peak-to-peak/188 watt RMS. 3 Sonar Sounding Depth capability:........... SeaCharter 642cDF iGPS: 1,500 feet (457 meters). FishElite 642c iGPS: 800 feet (244 meters). Actual capability depends on transducer configuration and installation, bottom composition and water conditions. All sonar units typically read deeper in fresh water than in salt water. Depth display:................ Continuous display . Audible alarms: ............. Deep/shallow/fish/zone. Automatic ranging:....... Yes, with instant screen updates. Auto bottom track:........ Yes. Zoom bottom track: ...... Yes. Split-screen zoom:......... Yes. Surface water temp: ..... Yes. Speed/distance log: ...... Optional (requires optional speed sensor). GPS Recording:........................MMC & SD cards for recording GPS trip details and displaying charts or custom maps. Receiver/antenna: ......... Internal; Built-in 12 parallel channel GPS/WAAS. Background map:.......... Built-in custom, detailed Eagle map. Contains: enhanced detail of continental U.S. and Hawaii. Includes more than 60,000 nav aids and 10,000 wrecks/obstructions in coastal and Great Lakes waters. Metro areas, selected major streets/highways and interstate exit services details included. Custom mapping: .......... MapCreate. 6 software optional; optional plug and play LEI FreedomMaps. offer the same high-detail without the computer work of MapCreate. Other plug and play mapping options include FreedomMaps., Fishing Hot Spots. Elite, LEI NauticPath. charts, LakeMaster. ProMaps and Navionics. charts. Mapping memory: ......... Up to 1 gigabyte on one MMC (or SD) card. Position updates: .......... Every second. 4 Position points: ............. 1,000 waypoints; 1,000 event marker icons. Audible alarms: ............. Arrival/off-course/anchor. Graphic symbols for waypoints or event marker icons: ................. 42. Routes:............................. 100, up to 100 waypoints per route. Plot Trails: ...................... 10 savable; up to 10,000 points per trail. Zoom range:.................... 40 ranges; 0.02 to 4,000 miles. NOTE: The above memory capacities refer only to the unit’s on-board memory. The amount of GPS or sonar data you can record and save for recall later is limited only by the number and size of the MMC cards you have. NOTICE! The storage temperature range for your FishElite 642c iGPS and SeaCharter 642cDF iGPS is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage in temperatures higher or lower than specified will damage the liquid crystal display in your unit. This type of damage is not covered by the warranty.

How Eagle 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 under water basics. Sonar is an abbreviation for SOund NAvigation and Ranging, a technology developed during World War II for tracking enemy submarines. A sonar consists of a transmitter, transducer, receiver and display. Here's how it locates the bottom and finds fish. The transmitter emits an electrical impulse, which the transducer converts 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 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 5 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 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 ca...
