Garmin GMR 1234 xHD3 Open Array Radar and Pedestal

Garmin GMR 1234 xHD3 Open Array Radar and Pedestal

Garmin GMR 1234 xHD3 Open Array Radar and Pedestal are a high-definition 12-kW magnetron radar system designed for superior weather, obstacle, and traffic detection for mariners on offshore vessels. It features advanced technologies like scan averaging and improved target-size processing for enhanced clarity.

Garmin GMR 1234 xHD3 Open Array Radar and Pedestal Key Features

• Powerful Performance: The system offers 12-kW output power with a maximum range of up to 96 nautical miles and a minimum range of 20 meters.
• Enhanced Clarity: It utilizes Scan Averaging Technology to reduce sea clutter and improve target display, along with angular target-size processing for better object shape interpretation.
• Dual Range with Overlay: This feature allows a single antenna to display side-by-side images with independent range settings on a compatible chart plotter. These images can also be overlaid on a chart.
• Automated Features: The system includes Dynamic Auto Gain to adjust levels in various water conditions and Auto Bird Gain to help locate potential fishing spots by identifying bird flocks.
• Safety and Awareness: True Echo Trails help identify collision threats by showing the history of moving targets, and MARPA target tracking can track up to 30 targets (requires heading sensor). A guard zone alarm is also available.
• Durable Design: The open-array antenna is rated for 100-knot commercial-grade wind, and the pedestal has a quiet drive motor for reliable use in challenging marine conditions.
• Connectivity: It connects to the Garmin Marine Network via a network cable, allowing for seamless integration with compatible Garmin chart plotters

Garmin GMR 1234 xHD3 Open Array Radar and Pedestal FAQs

• What is the maximum and minimum detection range? The maximum range of the Garmin GMR 1234 xHD3  is 96 nautical miles, while the minimum range is 20 meters.
• What is the wind rating? The antenna has a 100-knot commercial-grade wind rating.
• Does it support dual range with overlay? Yes, it has a dual-range feature that allows a single antenna to provide split-screen, side-by-side images on your compatible chart plotter, with independent range settings and controls for both close and long range. Either or both ranges can be overlaid on a chart (requires appropriate sensors, sold separately).
• Does it have features for anglers? Yes, it includes Auto Bird Gain and a bird mode pre-set to help locate flocks of birds at the water's surface, which can indicate the presence of fish.
• What is "Scan Averaging" technology? This is a new feature for Garmin magnetron radar that helps filter out sea clutter and interference, which enhances the detection and display of consistent targets.
• Does it support MARPA target tracking? Yes, it supports MARPA target tracking to track up to 30 targets and help avoid collisions, but this requires a heading sensor which is sold separately. 
• What are the power requirements?
  • The power input is 10-32 V DC.
• How should the radar be mounted to avoid interference?
  • The radar should not be mounted closer to a magnetic compass than the compass-safe distance value specified in the product specifications. It should be at least 1 m (40 in.) from any other transmitting equipment or cables carrying radio signals, and 2 m (6.5 ft) from SSB radios.
• What is included in the box?
  • The box typically includes the GMR xHD3 12 kW open array pedestal
     with the 4' antenna, a 15 m power cable, a 15 m network cable, a mounting hardware kit and template, and installation instructions.
• Are there high voltage concerns when servicing? Yes, the high voltage capacitors in the product can hold a charge well after disconnecting power. Take all necessary precautions against high voltage to avoid serious personal injury or death when servicing the unit.
