GET ROBUST MAGNETRON SCANNING IN A COMPACT GARMIN DOME RADAR

Loaded with advanced features typically found on open arrays, these powerful 18” and 24” dome radars offer superior traffic, obstacle and weather detection for peace of mind on the water.

4kW POWER OUTPUT, 48-NAUTICAL MILE MAX RANGE

SCAN AVERAGING TECHNOLOGY

IMPROVED TARGET-SIZE PROCESSING

SPLIT-SCREEN DUAL-RANGE DISPLAY

BIRD DETECTION

QUIET DOME DRIVE MOTOR

NEW SCAN AVERAGING TECHNOLOGY

A first for Garmin magnetron radar, scan averaging helps filter out sea clutter and interference to enhance the detection and display of consistent targets.


ANGULAR TARGET-SIZE ADJUSTMENT

Pulse expansion and angular target-size processing techniques optimize on-screen object shapes for better interpretation at all range scales.


FASTER SCANNING ANTENNA

Rotation speeds up to 60 rpm improve the redraw rate for faster target updates.


TRUE ECHO TRAILS

A historical “trail” of boats on the water is displayed on the screen, removing relative motion influence to help you quickly identify moving targets and potential collision threats.


DUAL RANGE WITH OVERLAY

A single radar antenna is capable of providing split-screen, side-by-side images on your compatible chartplotter, with independent range setting and controls for both close and long range. Overlay either or both ranges on a chart.


DYNAMIC AUTO GAIN

Gain automatically adjusts levels to optimum settings for harbors, near shore and offshore in open waters.

RADAR OVERLAY

See overlaid images on your chartplotter’s map screen (with appropriate sensors, sold separately).

HIGH-RESOLUTION RADAR

Pick out targets at a distance, thanks to narrow horizontal beamwidth and high antenna gain.

DUAL-RADAR SUPPORT

This provides redundancy and allows each display unit to pull data from different sources.

DYNAMIC SEA FILTER

Radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions.

AUTO BIRD GAIN

Locate flocks of birds at the water’s surface where baitfish are also likely to be found.


MARPA TARGET TRACKING

Track up to 30 targets to help avoid collisions (with appropriate sensors, sold separately).

GUARD ZONE

Set the safety zone, and receive an alarm when an object enters the zone.

RANGE AND BEARING CUES

Variable range markers and electronic bearing lines allow rapid measurements of distance and bearing to vessels and land.
