Product Overview

Broadband 3G™ Radar delivers amazing short-range target resolution, InstantOn™ warmup speed and the lowest available RF transmission for safe, flexible installations.

With revolutionary Frequency Modulated Continuous Wave (FMCW) technology, you see objects such as small boats and channel markers at greater distances.

Incredibly safe, Broadband 3G transmits 1/20,000 the power of traditional pulse radar—less than 1/10 the energy of a mobile phone—so it’s safe to install just about anywhere on your boat. Broadband 3G Radar supports chart overlay, display networking, MARPA and True Motion Radar Display to distinguish moving vessels from fixed objects or landmasses.

Key Features

  • Uuparalleled short-range target discrimination: Lowrance Broadband Radar™ provides amazing target resolution, even at an unprecedented 1/32 nm range. Docks, channel markers, moored vessels and other critical targets are displayed with pronounced clarity and separation, for added safety and confidence in close quarters.
  • No dead zone: Broadband Radar™ technology eliminates the "main bang" of pulse radar—an obscured viewing "dead zone" immediately around the boat—which prevents display of any close-in hazards.
  • Virtually no radiation for safe installation: Lowrance Broadband Radar™ transmits at 1/10,000 the power of typical pulse radars, emitting 5-times less energy than an average cell phone!
  • Flexible mounting options: Broadband 3G™ Radar is safe to mount in locations never before possible.
  • Low power consumption: With the lowest DC power draw of any X-band marine radar, it's the first and only radar ideally suited for sailboats and other fishing or cruising boats with limited power.
  • Navigation in an instant: No more waiting 2-3 minutes for a pulse radar magnetron to warm up. The 100% solid-state Broadband 3G™ Radar design provides InstantOn™ navigation in seconds. In darkness, fog or foul weather, you can view your surroundings, near and far, instantly. Ideal for sailboats and other boats wanting to save power, especially at anchor.
