VIDEO: Broadband 4G is the latest from Navico

Navico introduced the Lowrance, Simrad Yachting and B&G broadband 4G radars last month at the Fort Lauderdale International Boat Show. The 4G radar delivers 50 percent greater range and target detection than broadband 3G radar.

"We're getting tremendous returns of up to 36 nautical miles, and without increasing the power output at all," Navico spokesman Andrew Golden said while demonstrating the system on a 39-foot Yellowfin center console.

All of the 4G radars feature beam-sharpening technology, which provides the sharpest possible images, according to Golden. When networked with most display options, the radar has dual-range returns from a single scanner. The Lowrance, Simrad and B&G models are compatible, respectively, with the Lowrance HDS; Simrad NSO Offshore, NSE Expert and NSS Sport; and B&G Zeus multifunction displays.

Broadband 4G radar allows boaters to see a buoy 200 feet away while monitoring coastal projections up to 36 nautical miles, Golden said. And these radars can track up to 10 MARPA (Mini Automatic Radar Plotting Aid) targets per range — each with independent control — for a total of 20 tracked targets in split-screen mode, he added.

The 4G radars became available this month in the United States and Canada. The Lowrance has a minimum advertised price of $1,899; the Simrad and B&G have a suggested retail price of $2,299.
