The Furuno GP1871F 7 - inch multi - touch GPS/WAAS Chart Plotter combines a CHIRP and conventional fish finder, offering an outstanding marine navigation and fishing experience. With an all - glass design similar to TZtouch2, it features multi - touch controls, slide - out menus, and edge - swipe gestures for easy operation. It has a built - in 1kW TruEcho CHIRP and conventional fish finder with Accu - Fish, RezBoost, and bottom discrimination. The 72 - channel GPS WAAS, EGNOS, MSAS core, and internal antenna ensure accurate positioning. Wireless connectivity allows use with DRS4W Radar and C - MAP C - Weather downloads. Radar overlay is possible with DRS4W, and it's compatible with the C - MAP 4D MicroSD Worldwide Cartographic Database. C - MAP C - Weather provides wind, wave, weather, humidity, and temperature data. It can control an autopilot when integrated with NavPilot 711C or NavPilot 300. Certified NMEA2000/NMEA0183 interface accepts AIS data in both formats. The all - glass, multi - touch display gives intuitive access to all features. Chart Plotter uses C - Map 4D charts for better situational awareness. The fish finder offers various power options and advanced features. Radar can be wirelessly overlaid on the display, and NAVpilot can be connected for control (coming soon).

Using the Furuno GP1871F is a breeze. First, install it on your vessel using the mounting bracket and flush - mount kit provided in the box. Connect the power/data cable and make sure the input voltage is between 12 - 24 VDC. For the fish finder, tell the unit what transducer you're using, and it'll select the appropriate mode. To access different functions, use the slide - out menus on the multi - touch display. Slide down from the top for Quick Pages, left for Data Boxes, up from the bottom to adjust layer settings, and right for frequently used menu functions. When using the Chart Plotter, create routes and waypoints by simply touching the screen. If you connect an AIS receiver, you can view AIS data. To use C - Weather, download the relevant information. For radar overlay, connect wirelessly to the Furuno DRS4W. If you integrate with NavPilot 711C or NavPilot 300, you can control the autopilot from the Chart Plotter (coming soon). As for maintenance, use the cleaning cloth to keep the display clean. Avoid exposing the unit to extreme temperatures and moisture. Make sure to keep the micro SD card slots free from dust and debris. Also, note that a CHIRP dedicated transducer is required, and a dual - frequency CW compatible transducer is needed too.
