Simrad Halo 3004 130w Pulse Compression Radar System with 4' Antenna, 20m Cable and RI-50
Model: 000-15763-001The HALO® 3000 array radar offers a premium experience on the water. An impressive 130 W of power — equivalent to a 25 kW magnetron radar — delivers an unrivaled combination of short- and long-range coverage that enables you to see targets from six meters (20 feet) out to 96 nautical miles with exceptional clarity. Pulse Compression technology powers confident navigation through marinas, and superior storm and hazard detection across a greater distance. The HALO® array series not only increase situational awareness and collision avoidance but also offer higher-resolution target detection you won’t find in lower-powered radars.
The HALO 3000-series boast an array of new features that make navigation safer and offer peace of mind. ZoneTrack™ brings the best of professional boating technology to recreational users, allowing them to track up to 50 vessels within a defined area, automatically detecting their course and speed. HALO’s Dangerous Target Alerts highlight range, graphical bearing, and heading of other vessels relative to yours. Meanwhile, VelocityTrack™ uses Doppler technology to show targets color-coded so you can identify potential threats at a glance. Because, when it comes to safety, situational awareness is everything.
The next generation of pulse compression radars, HALO 2000 and 3000 build on the features that have made HALO an established choice for boaters across the globe. The solid-state technology gets you up and running quickly, and HALO’s low-power pulsed transmissions make it safe to run in harbors and marinas. Dual Range mode allows you to keep an eye on distant weather cells while monitoring channel markers and high-speed watercraft up close. Advanced digital signal processing gives you a clearer view of targets, helping eliminate sea clutter, while Beam Sharpening provides enhanced separation between small or distant targets. Finally, HALO 2000 and 3000 have the same footprint as their predecessors, making it easy to upgrade your current system. It’s also compatible with a range of Simrad® chart plotters, including NSS™, NSX™, NSO™, and GO™.
Designed with an intuitive interface HALO arrays make operation easier with smart features like Harbour, Offshore, Bird, and Weather modes. These Preset Modes require no manual tuning — just select your chosen mode and go. This simple approach also extends to fishing, with HALO’s powerful bird-finding capability which enables boaters to find flocks of birds and — more importantly — schools of fish at a distance.
Designed with an intuitive interface, HALO 3000 has smart features like Harbour, Offshore, Bird, and Weather modes. These Preset Modes require no manual tuning — just select your chosen mode and go. This simplified approach also extends to fishing, with HALO 3000’s powerful Bird+ mode — a must-have tool for sportfishing enthusiasts. Bird+ mode allows you to focus the full 130W of HALO 3000’s power on bird finding, enabling boaters to find schools of fish up to 8nm away.
