HALO20+ Radar - A compact 20'' powerful 25 W Solid-State Radar, delivering 60 RPM at short range and up to 36 NM range. Identify hazards in an instant with VelocityTrack™ Doppler technology and can run dual scale to identify hazards both at close and long ranges simultaneously.
Overview
HALO20+ radar offers 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 one compact 20-inch dome antenna.
The Ultimate View for Collision Avoidance
HALO20+ radar incorporates industry-leading 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.
