A distinguishing feature of Garmin’s new 2- and 4-kW radomes is their low profile—only eight inches without the optional pedestal—and extra-wide, 28-inch diameter. The latter dimension means that these units boast a 3.6-degree horizontal beam width, narrower than more conventional 24-inch domes, and hence yielding more precise target discrimination. Plus the processing electronics are all built into the dome and output via Ethernet cable to a router and then onto to Garmin’s 3000 series multifunction displays, which means simplified installation and a scanner that’s nicely independent of any one display’s malfunction.
The results looked good during trials at the Miami International Boat Show, as did the radar’s full and well-implemented control and feature set, which includes MARPA anticollision tracking. The 24-mile-range GMR 20 is $1,920, and the 36-mile GMR 40 is $2,347.
