B&G HALO24 24” Radar Dome with Doppler (VelocityTrack) – 48 NM Pulse Compression Radar w/ 20m Cable
B&G HALO24 Doppler radar dome with 20m cable. 48 nm range, Dual Range, 60 RPM close-range sweeps, VelocityTrack, beam sharpening, IPX6, Instant On.

The B&G HALO24 24” Radar Dome with Doppler Technology (20m Cable) delivers high-definition target detection from short range all the way out to 48 nautical miles—ideal for sailboats, fishing boats, and smaller powerboats that demand confident navigation in any conditions. Using solid-state pulse compression and beam sharpening, HALO24 provides excellent target separation with reduced clutter, helping you spot small craft, buoys, land features, and weather cells with clarity.
For superior situational awareness, Dual Range mode lets you monitor near and far ranges at the same time, so you can track distant weather while watching for close-range collision hazards. At close range, HALO24 offers an industry-leading 60 RPM rotation up to 2 nautical miles, completing a full 360° sweep every second for an almost real-time view—an advantage in crowded waterways and poor visibility.
Built-in VelocityTrack™ Doppler technology instantly indicates whether targets are approaching or moving away using simple color coding. HALO24 automatically checks every target on screen without requiring manual selection, improving awareness and reducing collision risk. The low-profile, lightweight dome includes integrated LED lights, and wakes instantly from standby thanks to Instant On™ solid-state technology.
