Unique Selling Points
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 you’re 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; there’s 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. VelocityTrack™ requires a heading sensor and GPS.
