GR-2000 Marine GPS Receiver



The GR-2000 is the ideal position and heading device. The GR-2000 is built with NMEA 2000 new world standard in marine electronics data protocol. It is brilliant for networking with multiple instruments on boat which is NMEA 2000® certified devices (sensor, sonar, GPS, multi-function gauge, etc.), regardless of brand, will share and/or display user-selectable data with any or all other display instruments installed in a NMEA 2000® network. The GR-2000 offers unique advantages for networking package for multi-station sensing and display of boat systems and engine functions. Those key benefits include simplicity, easy installation, versatility and ease of sensor/display/system expansion, excellent performance and amazing affordability. The advanced precision GPS receiver module applied not only provides extremely accurate and rapid boat position and speed updates, the electronic compass also provides heading for accurate and boat direction at any speed and for radar/chart overlay. The GR-2000 is fully waterproof and can be Pole or surface mounted on any boat.
