Ideal for coastal navigation of small boats and fishing boats. Equipped with a compact Dome antenna offering high quality short medium and long range detection. Pulse compression signal management and InstantOn technology for quick use at start-up. Easy to use thanks to the various modes of use such as Harbor Offshore Weather North Up Course Up Relative motion True Motion which exploit an advanced signal processing to ensure a clear view of the targets even in the most difficult environmental conditions. In addition to the above the HALO20 + plus model offers additional functions. Simultaneously monitors two distances in Dual Range mode to keep an eye on remote storm cells and control close-up collision risks. The impulse compression technology does not compromise in the detection of any distance and the narrowing of the beam offers a better separation between distant or small targets. VelocityTrack � technology provides instant visual feedback on approaching or moving targets away. The simple color coding highlights the potential risks and dangers for a better knowledge of the surrounding environment and to further reduce the risk of collision. The radar automatically controls every obstacle within its range of action without the need to manually select the targets one by one and without a maximum number of obstacles that can be displayed simultaneously on the screen. Performs a full 360-degree scan every second thanks to an industry-leading 60 rpm rotation mechanism for distances up to 1.5 nautical miles. These ultra-fast upgrades offer near-real-time close-up view the best solution to avoid collisions with fast moving obstacles.
