The GMR Fantom 256 combines long-range detection with target-management features. Its 96-nautical-mile maximum range supports extended situational awareness, while the 6-meter minimum range supports close-range detection. The 1.25° horizontal and 23° vertical beam specifications define the stated radar coverage characteristics.
Dual-range operation allows two distance scales to be monitored, while radar overlay can place radar information alongside compatible navigation data. Dual-radar support is also specified for installations using more than one radar source.
MotionScope is designed to highlight moving targets. The radar also provides echo trails, dynamic automatic gain, Auto Bird Gain, programmable antenna parking, target-size adjustment and scan averaging.
MARPA target tracking is specified when a suitable heading sensor is used; the heading sensor is sold separately. System compatibility should therefore be confirmed when planning the installation.
The 72-inch antenna and pedestal assembly require substantial mounting space. The listed full assembly dimensions are 15.9 inches high and 75.2 inches in diameter. The array weighs 16.0 pounds and the pedestal weighs 34.7 pounds, so the mounting structure should be selected for the complete assembly and its operating environment.
The radar accepts 10–32 V power input. The 48 rpm high-speed setting is subject to the stated limitations: it is available in single-range mode with MotionScope disabled and on range settings of 12 nautical miles or lower. Confirm compatibility with the vessel’s existing marine electronics before installation.
The Garmin GMR Fantom 256 is suitable for offshore navigation, fishing and other boating applications where long-range radar awareness is important. Its open-array design and feature set can also suit installations requiring radar overlay, dual-range viewing or multiple radar systems.
When comparing marine radar systems, consider required range, antenna size, beam characteristics, mounting space, power requirements and integration with existing electronics. Open-array systems also require careful attention to mounting strength and clearance. Explore our Marine Radar collection or contact Performance Engines for product and purchasing information.
