18 HD3 RADAR DOME

The Garmin GMR 18 HD3 Radome provides 4-kW transmit power and clear echo definitions at all ranges. It features dynamic auto gain and dynamic sea filter. This unit has MARPA Target Tracking to track select targets in order to keep track of other vessels and avoid collisions, as well as Dynamic Auto Gain to automatically adjust levels to optimum settings, and Dynamic Sea Filter that automatically adjusts sea clutter for calm, medium and rough sea conditions. It also has dual-radar support that provides redundancy and allows each display unit on the boat to pull data from one or two different radar sources, and timed transmit mode that allows the user to specify transmit time to reduce power consumption.
