Open array marine radar systems from Garmin, Raymarine, and Simrad deliver long-range offshore radar performance, superior target separation, and faster antenna rotation compared to dome radar systems.

Designed for center console fishing boats, sportfish vessels, offshore cruisers, and commercial marine navigation, open array radar antennas provide extended detection range, wider sweep coverage, and better visibility in heavy weather, fog, and low-visibility conditions.

This collection includes Garmin GMR Fantom open array radar, Raymarine Cyclone open array radar, and Simrad HALO open array radar antennas, built for integration with modern chartplotters and multifunction displays for advanced navigation, collision avoidance, and bird-finding offshore.

High-Performance Open Array Radar for Offshore Navigation

Open array radar systems use longer rotating antennas to deliver significantly greater detection range and improved target definition compared to compact dome radar units. These radars are widely used on offshore fishing boats where early target detection and precise tracking are critical.

  • Long-range radar detection for offshore navigation
  • Enhanced target separation for boats, land, and weather systems
  • Faster antenna rotation for smoother radar updates
  • Ideal for sportfishing boats, center consoles, and cruisers
  • Designed for integration with modern marine electronics

Open Array Radar vs Dome Radar

One of the most common upgrades boat owners make is switching from a compact dome radar to an open array radar system. Open arrays offer stronger performance for offshore boating and long-distance navigation.

  • Longer antenna length increases radar range
  • Higher power output improves detection in rough conditions
  • Superior bird detection for offshore fishing
  • Improved radar clarity and target tracking
  • Ideal for larger center consoles and offshore vessels
