Specification BatteriesRequired : 1 Brand : Garmin BulletPoint : Radar, Quantum 2 w/ Doppler, 15m Cable BulletPoint1 : High-Resolution Radar BulletPoint10 : Set the safety zone, and receive an alarm when an object enters the zone. BulletPoint2 : 4 KW power output, 48 nautical mile max range BulletPoint3 : Improved target-size processing BulletPoint4 : See overlaid images on your chartplotter’s map screen (with appropriate sensors, sold separately). BulletPoint5 : Pick out targets at a distance, thanks to narrow horizontal beamwidth and high antenna gain. BulletPoint6 : This provides redundancy and allows each display unit to pull data from different sources. BulletPoint7 : Radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions. BulletPoint8 : Locate flocks of birds at the water’s surface where baitfish are also likely to be found. BulletPoint9 : Track up to 30 targets to help avoid collisions (with appropriate sensors, sold separately).

Overlay either or both ranges on a chart.Dynamic Auto GainGain automatically adjusts levels to optimum settings for harbors, near shore, and offshore in open waters.Radar OverlaySee overlaid images on your chartplotter’s map screen (with appropriate sensors, sold separately).High-Resolution RadarPick out targets at a distance thanks to a narrow horizontal beamwidth and high antenna gain.Dual-Radar SupportThis provides redundancy and allows each display unit to pull data from different sources.Dynamic Sea FilterRadar gain automatically adjusts sea clutter for calm, medium, and rough sea conditions.Auto Bird GainLocate flocks of birds at the water’s surface, where baitfish are also likely to be found.MARPA Target TrackingTrack up to 30 targets to help avoid collisions (with appropriate sensors, sold separately).Guard ZoneSet the safety zone and receive an alarm when an object enters the zone.Range and Bearing CuesVariable range markers and electronic bearing lines allow rapid measurements of distance and bearing to vessels and land.In the Box: GMR 18 xHD3 dome radar Power cable (15 m/49.21 ft) Network cable (15 m/49.21 ft) Mounting hardware kit and template Installation instructions General: Dimensions: 20" x 9.8" (508 mm x 248 mm) Weight: 7.0 kg Waterproof: IPX7 Antenna length: 17" (43 cm) Rotation Speed (RPM): Up to 60 RPM, depending on settings Beam Width: 5.2° horizontal, 25° vertical Maximum Range: 48 nm Minimum Range: 20 meters Radar Type: Radome Electrical Features: Power Input: 11-32 v DC Power Consumption (Standby): 15 W Typical Power Consumption, Transmitting (Normal Mode): 40 W Transmit Power: 4 KW Radar Features: Dual Range: Yes Overlay: Yes Dual Radar Support: Yes Auto Bird Gain: Yes Auto Gain: Dynamic MARPA Target Tracking: Yes (requires heading sensor, sold separately) Echo Trails: True Target Size: Yes Scan Averaging: Yes ProductSiteLaunchDate : 2023-09-28T18:50:42.356Z Size : One Size SportType : Boating Style : Radar Dome SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredDgHzRegulation1 : not_applicable SupplierDeclaredDgHzRegulation2 : not_applicable SupplierDeclaredDgHzRegulation3 : not_applicable SupplierDeclaredDgHzRegulation4 : not_applicable SupplierDeclaredDgHzRegulation5 : not_applicable UnitCount : 1 WarrantyDescription : 2 year limited warranty
