Perfect for a wide mid-sized to large sailboats, HALO20+ comes in a compact 20-inch dome antenna and delivers high-quality short, mid and long-range detection.

Monitor two distance ranges at once in Dual Range mode so you can 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 Best View To Avoid Collision

HALO20+ radar does a full 360 degree sweep every second, thanks to its industry-first 60 RPM rotation at ranges up to 1.5 nautical miles.

These ultra-fast updates give you an almost real-time view at close range, offering the ultimate view for collision avoidance of fast moving targets.

Built-in VelocityTrack™ Doppler Technology

VelocityTrack™ technology grands instant visual feedback on whether targets are coming towards you or moving away with colour-coding approaching vessels for high visibility while de-emphasizing diverging targets, increasing situational awareness and decreasing the risk of collision.

HALO20+ radar automatically checks every target in range; there’s no need to manually select individual targets, and no limit to the number of targets on screen at one time.

Ready Whenever You Are

HALO20+ Radar wakes instantly from its low-power standby mode, delivering this high-speed radar coverage exactly where and when you require it.

Even if your HALO20+ Radar is completely powered down, start-up only takes some seconds, not minutes like traditional pulse radar.

Easy to Use Radar

Harbour, offshore, weather 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.
