Product details
The compact size of the Garmin GMR18 HD+ radome radar antenna makes it ideal for boats where radar antenna space is limited. Its 4 kW transmit power ensures clear signals are transmitted and received over all ranges, making it easier to interpret radar echoes, increasing situational awareness, especially in poor visibility. Received radar echoes can be laid over a Garmin chartplotter map as a so-called radar overlay. For a smooth and jitter-free radar overlay the use of an optional heading sensor such as the 9-Axis Heading Sensor (item: 81775) or an autopilot system with heading sensor is necessary. Furthermore, the Garmin GMR18 HD+ in combination with a compatible heading sensor and a multifunction display supports further functions such as MARPA (Mini-Automated-Radar-Plotting-Aid) target tracking.
Thanks to the dynamic automatic amplification of echoes, the radar image adapts to the current surroundings, thus ensuring optimum performance in all conditions. In addition, the dynamic sea state filter adjusts sea clutter depending on the current sea conditions. A clear display on Garmin chartplotters is achieved by the GMR18 HD+'s 8-bit True Color resolution. Maximum range is 36 nautical miles, minimum range is a good 20 meters and rotation speed is 24 rpm.
