HD Digital Radar systems combine high performance 2 to 25kW scanners and microwave technology with the latest digital signal processing.MAIN FEATURESRadar/Chart Overlay - interfaces charts and radar detail in a single, detail-rich display when coupled with an optional,compatible NMEA0183® or NMEA2000® heading sensor.Clearest Viewing - Automatic Tune, Gain and Sea Clutter adjustments provide “hands off” operation in Harbour and Offshore Modes.Smart STC - Digital Sensitivity Time Control curves reject clutter with setting of return strength/distance thresholds.Color Recognition - Color palette choices for improved target distinction based on viewing conditions.MARPA/Guard Zones - target tracking of up to 10 targets and dual guard zones.NS series support MARPA target tracking and dual guard zones with these HD radars.HD pulse radars are designed for boaters that go really far from land and want to see the details in weather cells>20nm away. In fact, the 25kW has proven to see tall storms as far as 100nm away.The Open Arrays are best for BIRD finding. Remember – the longer the array the better the resolution and target separation.If navigation is primary importance, recommend Broadband 4G and 3G Radars instead.2kW is for 12V systems only. 4/6kW work on 12/24V, while 10/25kW need 24V.HD digital radars automatically adjust color gradients on longer range for better interpretation of targets. This is especially useful when looking into storm areas and weather fronts.Radar allows the cursor to be placed over an anchored vessel to gather the latitude/longitude position. Great for pinpointing new potential fishing spots without being recognized.FAQAll Pulse Radars always have a blind spot at the center on shortest ranges.Be sure to use our RC42 rate compass for best Chart and MARPA overlay performance for HDS/NS series.It is usually OK to operate 2 pulse radars on the same boat, if physically separated by at least 6’ and interference rejection (IR) is set high on both scanners.Never look into a pulse radar or stand close to it while it is operating. The more powerful the radar, the farther the safe distance becomes.
