Chartplotter 431s with Dual-beam Transducer

The GPSMAP 400 Series compact chartplotters feature an ultra-bright 4" QVGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. They’re ready to go with an easy-to-use interface and a choice of three built-in, satellite-enhanced basemaps. The GPSMAP 421 plotters come preloaded with a satellite-enhanced worldwide basemap. Inland lake boaters can choose the 431, which adds U.S. Inland Lakes. GPSMAP 441 includes all U.S. coastal areas, including Alaska and Hawaii as well as detailed charts for Bahamas. All three also accept BlueChart® g2 Vision cards for added features and functionality such as high-resolution satellite imagery, 3D views and Auto Guidance technology, and are equipped with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. Add sonar with the “S” versions. They run either 50/200kHz dual frequency (500W) or 80/200kHz dual beam (400W) transducers. The GPSMAP 421, 441, 421s and 441s are also NMEA 2000-certified for easy connectivity with sensors, instruments and future marine offerings. In addition, these units (but not the 431 and 431s) can receive U.S. graphical weather data via optional GXM 51 satellite receiver/antenna. And with an SD card slot, it’s easy to add additional maps without connecting to a computer. Transducers sold separately. '
