Chartplotter Onwa KM-8A
AIS chartplotter KM-8A displays 700 targets, tracks 1000 automatically saved, 10 manually saved tracks. The chartplotter memory can store 12,000 user waypoints, 3 system waypoints, 30 routes. Has an automatic track log for 8,000 points, makes it possible to track the vessel’s route in both directions. The Onwa chartplotter is compatible with GNSS GPS, Beidou.
The GPS receiver of the chartplotter with 50 parallel channels continuously tracks the location of the vessel using up to 50 satellites. The navigation device can operate in harsh conditions. The display and antenna unit comply with the IPX6 protection class: they will withstand the effects of water flows from any direction. Operating temperatures of the display: from -15℃ to +55℃, antenna unit: from -25℃ to +70℃.
