B&G HALO20+ 20” Radar Dome – 36 NM Pulse Compression Radar with 20m Cable, Dual Range & VelocityTrack

The B&G HALO20+ 20” Radar Dome with 20m Cable delivers exceptional short-, mid-, and long-range target detection in a compact dome—ideal for mid-sized to large sailboats needing maximum awareness in a smaller footprint. With advanced pulse compression and beam sharpening, HALO20+ provides clear target separation and reduced clutter, helping you pick out small or distant targets with confidence.

For improved situational awareness, Dual Range mode lets you monitor two ranges at once—track distant weather cells while keeping close-range collision hazards in view. When navigating tight quarters, HALO20+ offers an industry-leading 60 RPM rotation at ranges up to 1.5 nautical miles, completing a full 360° sweep every second for near real-time close-range updates.

Built-in VelocityTrack™ Doppler technology instantly color-codes targets approaching versus moving away, increasing visibility of collision threats and reducing the workload of interpreting returns. The radar automatically evaluates targets in range with no need to manually select them, while MARPA target tracking supports monitoring up to 10 targets (or 20 in dual range). With instant wake from standby and fast startup from power-down, HALO20+ is ready whenever you are.
