B&G HALO20+ Radar


The HALO20+ comes in a compact dome antenna and delivers high-quality short, mid and long-range detection, ideal for a wide range of mid-sized to large sailboats.

Two distance ranges can be monitored at once in Dual Range mode which enables the user to keep an eye on far away weather cells while watching for collision hazards up close.

HALO20+ radar’s pulse compression technology means no compromises in detection at either selected range, while beam sharpening provides enhanced separation between small or distant targets.

The radar unit delivers a full 360 degree sweep every second, thanks to its 60 RPM rotation at ranges up to 1.5 nautical miles. These ultra-fast updates give an almost real-time view at close range, offering the ultimate view for collision avoidance of fast-moving targets.

VelocityTrack™ technology provides instant visual feedback on whether targets are coming towards the vessel or moving away. Simple colour coding highlights potential hazards, improving situational awareness and further reducing risk of collision. The radar automatically checks every target in range so there’s no need to manually select individual targets, and no limit to the number of targets on screen at one time.

HALO20+ wakes instantly from its low-power standby mode, delivering high-speed radar coverage exactly when and where needed. Start-up is a matter of seconds, even if the device is completely powered down.

Whether navigating through crowded waterways or contending with poor visibility, HALO20+ Radar immediately cuts through the clutter to offer a clear and current picture of surroundings.

Harbour, Offshore, Weather, Bird, and custom modes tune HALO20+ Radar’s advanced signal processing to help ensure that targets can be seen vividly - even in the toughest environmental conditions.
