Simrad HALO-4 Pulse Compression Radar

See Near and Far, Simultaneously

Halo™ radar delivers an unprecedented mix of short and long range performance with its 4-foot open array, from just six metres (20 feet) to as far as 64 nautical miles. Monitor two distance ranges simultaneously in Dual Range mode, and take full advantage of Halo radar to keep an eye on faraway weather cells while monitoring channel markers and high speed watercraft up close. Pulse Compression technology means no compromises in detection at either range. Advanced digital signal processing helps to eliminate sea clutter, while Beam Sharpening technology provides enhanced separation between small or distant targets.

Safety, Weather, and Bird-Finder Radar

Halo radar delivers a comprehensive range of features to enhance your situational awareness and on-water safety. Monitor selected collision hazards with MARPA target tracking, or automatically highlight all approaching targets with the optional VelocityTrack™ Doppler motion-tracking upgrade. Keep watch on distant storm cells in Weather mode, your own real-time meteorological service. Halo radar also works as a powerful bird-finder, a must-have tool for sportfishing enthusiasts and pro anglers. Halo radar’s smart Weather and Bird modes require no manual tuning, just set the mode and go.

Ready in an Instant

Collision hazards won’t wait for your radar to start up – why should you? Halo radar’s solid-state technology is ready instantly from standby, and in just 16-25 seconds from a cold start. Avoid the 2-3 minute warm-up time associated with traditional pulse radar and trust Halo Radar to produce an immediate, accurate radar image when you need it. Halo radar’s low-power pulsed transmissions make it safe to run in anchorages and marinas, providing additional coverage in these high-collision-risk environments. Fast 48 RPM operation provides frequent position updates, while an advanced brushless motor and helical geartrain ensure quiet operation.
