Overview
HALO20 radar is a cost-effective solution for boaters to increase situational awareness and collision avoidance, detecting collision hazards and other targets nearby and up to 24 nautical miles away. With its small footprint and low profile, HALO20 is the perfect radar solution for more budget-conscious buyers with smaller sportfishing vessels and dayboats.
HALO20 radar also delivers a comprehensive range of features to enhance your situational awareness and on-water safety. Boaters can monitor selected collision hazards with MARPA target tracking, tracking up to 10 targets. Whether navigating through crowded waterways or contending with poor visibility, HALO20 radar cuts through the clutter to give boaters a clear and current picture of their surroundings.
Unrivalled Short-to-Mid-Range Performance
Extend your view from the bow of your boat out to 24 nautical miles with pulse-compression radar technology that not only delivers a powerful mix of short and long-range detection, but provides precise target definition with minimal clutter.
Better Situational Awareness, Collision Avoidance
HALO20 radar delivers a comprehensive range of features to enhance your situational awareness and on-water safety. Monitor selected collision hazards with MARPA target tracking, tracking up to 10 targets. Whether you’re navigating through crowded waterways or contending with poor visibility, HALO20 radar cuts through the clutter to give you a clear and current picture of your surroundings.
Easy to Use
Harbour, Offshore and Weather modes tune HALO20 radar’s advanced signal processing to help ensure that targets can be seen vividly – even in the toughest environmental conditions.
Ready When You Are
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 is completely powered down start-up is a matter of seconds, not minutes like traditional pulse radar.
