HALO20+ Radar

Get an almost real-time view with HALO20+. Industry-leading 60 RPM operation at close range provides the best in collision avoidance. Identify hazards instantly with VelocityTrack™ Doppler technology, and enjoy both short and long-range coverage—up to 36 nautical miles—from a compact 20-inch dome antenna.

Quality Short-to-Mid-Range Performance

Extend your view from the bow of your boat up to 24 nautical miles with pulse-compression radar technology that delivers a powerful mix of short and long-range detection, as well as precise target definition with minimal clutter.

See Near and Far with One Compact Dome

Perfect for coastal bay and fishing boats, HALO20+ radar is a compact dome antenna that delivers high-quality short, mid and long-range detection. Monitor two distances at once in Dual Range mode which lets you keep an eye on far away weather cells while looking for closer collision hazards. Pulse compression technology means no compromises in detection at either range, and beam sharpening provides improved separation between small or distant targets.


The Best View for Collision Avoidance

HALO20+ radar performs a full 360 degree sweep every second because of its industry-first 60 RPM rotation at distances of up to 1.5 nautical miles. These ultra-fast updates give you an almost real-time view at close range, the best view for collision avoidance of fast moving targets.

VelocityTrack™ Doppler Technology Built-In

VelocityTrack™ technology gives instant visual feedback on whether targets are approaching or moving away. Simple color coding highlights potential hazards, improving your situational awareness and further reducing your risk of collision. HALO20+ radar automatically checks every target in range; no need to manually select individual targets, and no limit to the number of targets on screen at one time.

HALO20+ Radar wakes instantly from its low-power standby mode, delivering high-speed radar coverage exactly when and where you need it. Even if your HALO20+ Radar is switched off, start-up is a matter of seconds, not minutes like traditional pulse radar. Whether you’re navigating crowded waterways or dealing with poor visibility, HALO20+ Radar immediately analyses your surroundings to give you a clear and current picture.
