HALO20+ delivers an almost real-time view, with industry-leading 60 RPM operation at close range for the ultimate in collision avoidance. Identify hazards in an instant with VelocityTrack™ Doppler technology, and enjoy simultaneous short and long-range coverage—up to 36 nautical miles—from a compact 20-inch dome antenna.

See Near and Far with One Compact Dome

Perfect for a wide range of coastal bay boats, HALO20+ comes in a compact dome antenna and delivers high-quality short, mid and long-range detection. Monitor two distance ranges at once in Dual Range mode which enables you 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 Ultimate View for Collision Avoidance

HALO20+ radar delivers 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. 

VelocityTrack™ Doppler Technology Built-In

VelocityTrack™ technology provides instant visual feedback on whether targets are coming towards you 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; there’s no need to manually select individual targets, and no limit to the number of targets on screen at one time. 

Ready When You Are

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