This compact 18″ dome radar combines ease of use with powerful scanning features that work to maximise your confidence and situational awareness on the water.
4kW POWER OUTPUT, 36-NAUTICAL MILE MAX RANGE
SPACE-SAVING 18″ DOME
MARPA TARGET TRACKING
Additonal sensors required*
DYNAMIC AUTO GAIN AND SEA FILTER
DUAL-RADAR SUPPORT
QUIET DOME DRIVE MOTOR
DUAL-RADAR SUPPORT
Using dual radar provides redundancy and allows each display unit on the boat to pull data from one of two different radar sources.
DYNAMIC AUTO GAIN
Gain automatically adjusts levels to optimum settings.
DYNAMIC SEA FILTER
Radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions.
RADAR OVERLAY
Overlay radar images onto your chartplotter’s map page. You can add an optional autopilot or heading sensor (sold separately) for best results.
MARPA TARGET TRACKING
MARPA tracks selected targets to help keep track of other vessels and avoid collisions (with appropriate sensors, sold separately*).
LOW-NOISE SCANNING
The reliable GMR HD3 dome drive motor spins at a fixed 24 rpm, offering reliable, low-noise operation and minimal power consumption.
COMPACT AND POWERFUL
4kW of transmit power, 36-nautical mile maximum range and clear echo definition at all ranges.
CLOSE-IN TARGET SCANNING
Minimum scanning range of 20 metres for excellent short-range detection and target detail
HIGH-RESOLUTION RADAR
8-bit true colour for outstanding target separation with less screen clutter.
TIMED TRANSMIT MODE
Specify transmit times down to the seconds to help reduce power consumption.
INTUITIVE OPERATION
No complex user settings, so it’s easy to install and start using.
