Dom Radar Garmin GMR HD3 18

Garmin GMR HD3 18 Dome Radar

The Garmin GMR 18 HD3 is a 4kW magnetron dome radar designed for high performance. With a maximum range of 36NM, it ensures clear and accurate detection even in low visibility conditions, providing essential information for safe navigation. The dome's rotation motor operates quietly at a fixed speed of 24RPM, reducing energy consumption.

The radar uses 8-bit true-color technology for better target definition and clear separation. The Timed Transmit Mode feature allows precise control of active transmission periods, optimizing power consumption and extending battery life on the water. The interface is intuitive and supports split-screen display with independent ranges on compatible chartplotters. The Dual-Radar function adds redundancy and flexibility between signal sources.

Integrated features include Dynamic Auto Gain, Dynamic Sea Filter, Radar Overlay, and MARPA target tracking (with additional sensors), along with guard zones and quick VRM/EBL measurements.
