Scanners: B&G BR24 4G BROADBAND RADAR FOR ZEUS (000-10423-001)

Joining the family of award-winning Broadband 3G™ Radar and BR24 Broadband Radar™ — the world’s first recreational marine FMCW system — Broadband 4G Radar delivers 50-percent greater range and target detection than Broadband 3G Radar. All 4G radar models feature revolutionary Beam Sharpening technology that provides the sharpest-possible radar images. When networked with most display options, the new Simrad and B&G Broadband 4G models also have the unprecedented ability to present dual-range radar returns from a single scanner, combined with the benefits of greater high-speed operation.* For optimal target separation, Broadband 4G Radar is the world’s first dome radar to use Beam Sharpening, which significantly improves azimuth resolution — the effective horizontal beam width of the radar signal. The result is a resolution that is equivalent to a 3.5-foot, open-array radar. When combined with a B&G Zeus multifunction display, the system’s user-defined, target-separation control allows users to adjust the level of separation to meet specific navigational needs.

The B&G Broadband 4G Radars’ exclusive dual-range functionality makes them the only recreational radars capable of displaying distances from 200 feet to 36 nautical miles — all from a single dome. The ultimate navigational safety tool, Broadband 4G Radar allows boaters to see a buoy 200 feet away on the multifunction display, while simultaneously monitoring coastal projections up to 36 nautical miles. In addition, B&G Broadband 4G Radar models can track up to 10 MARPA targets per range — each with independent control, for a total of 20 tracked targets in split-screen mode.

All Broadband 4G Radars provide an unequalled number of working ranges, 18, for premier performance and navigational awareness. Providing intuitive and easy-to-use operation, each model also features smart, pre-defined Offshore and Harbour modes on all ranges without requiring special tuning knowledge.

Broadband 4G Radar not only raises the bar in radome performance by providing far superior resolution at long-range distances, it also delivers the same exceptional close-range capability that is signature to Broadband Radar. The system marks objects within 2 meters (6.5 feet) of the boat, providing target definition and separation in close quarters where traditional pulse radar is blind. Maintaining high-sensitivity and clarity in all weather conditions, the radar provides easy-to-view detail of targets even in high-sea states.
