NEW Beam Sharpening. Broadband 4G Radar is the onlydome radar in the world to employ beam sharpening, which allows you to control the level of target separation, so you can see the sharpest images possible when you need them most.
NEW More Range 50% more true range than Broadband 3G Radar. Now you can see crystal clear targets up to 32nm away and inside strong storm cells more than 17nm away.
NEW Dual Range Capable of displaying Dual Range radar combination when combined with an NSE or NSO system. Monitor targets from 200 feet to 32nm from a single dome.
NEW High Speed Mode Select 48 RPM for almost instant updating at less than 1nm.
MARPA Target Tracking Track up to 10 targets as standard or up to 20 in Dual Range mode with independent control.
Quick Installation No reason to open the dome, no tune or zero mile adjustment, and no radar-licensed technician required.
Dual Guard Zones Protect yourself from more angles.
Extremely Low Emissions Safer than any other radar currently on the market and emitting less radiation than a mobile phone allowing it to be mounted anywhere.
True Motion Display Easily distinguish moving targets from land with NSS, NSE and NSO.
InstantOn™ Solid-state technology produces an immediate, accurate on-screen image unlike normal warm-up times associated with magnetron pulse radars.
Low Power Consumption Ideal for boats of any size, sail, cruise or fish.
Automatic Clarity Proven auto harbour and offshore modes including directional clutter rejection.
