B&G HALO24 Radar Dome with Doppler Technology – 48 Nautical Mile Range, 60 RPM Fast Sweep, Dual Range and VelocityTrack

HALO24 Radar Dome with Doppler Technology

HALO24 radar offers an almost real-time view, with industry-first 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 coverageup to 48 nautical milesfrom one compact 24-inch dome antenna.

See Near and Far with One Compact Dome

Perfect for a wide range of sailboats, fishing boats and smaller powerboats, HALO24 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. HALO24 radars 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

HALO24 radar introduces industry-first 60 RPM rotation at ranges up to 2 nautical miles, delivering a full 360-degree sweep every single second. These ultra-fast updates give you an almost real-time view at close range, offering the ultimate view for collision avoidance. Whether youre navigating through crowded waterways or contending with poor visibility, Halo radar cuts through the clutter to give you a clear and current picture of your surroundings

VelocityTrack Doppler Technology Built-In

VelocityTrack technology provides instant visual feedback on whether targets are coming towards you or moving away. Using the Doppler effect, this feature automatically checks every target seen by your radar; theres no need to manually select individual targets, and no limit to the number of targets on screen at one time. Simple colour coding highlights potential hazards, improving your situational awareness and further reducing your risk of collision.
