Broadband 4G™ Radar

Product details

See Near and Far

Broadband 4G™ radar relies on solid-state FMCW technology to detect targets from right off the bow out to 36 nautical miles away. See clearly at close range, where traditional radar systems can be blind to imminent collision hazards. Monitor two different range scales simultaneously in dual-range mode, and keep watch on nearby vessels while also keeping an eye on distant weather cells or landmarks. Beam Sharpening technology enhances target separation, giving you the sharpest images possible, while Harbour and Offshore modes optimise the radar image for ultimate clarity with no manual tuning required.

Designed for Situational Awareness

Great short-range performance makes Broadband 4G radar fantastic for tight manoeuvres in marinas, and for safe navigation in limited visibility such as darkness or fog. High-speed 48 RPM operation is available at ranges less than one nautical mile, delivering ultra-fast updates to maximise safety at times of high collision risk. MARPA target tracking lets you monitor up to ten selected radar targets (20 in dual-range mode), while dual guard zones automatically alert you of nearby hazards.

Perfect for Vessels of All Sizes

Low power consumption makes Broadband 4G radar ideal for boats of any size and type. InstantOn™ capability means no warm-up time from standby, giving you an immediate radar image when you need it without having to keep the system running when you don’t. A closed dome design and zero radiation hazard—with lower energy emissions than a mobile phone—make the system safe to mount almost anywhere on board. Installation is quick and easy, with no reason to open the dome and no radar-licensed technician required.
