NEW KM12C with Sounder (includes transducer)

Latest KM series 12 ” chart plotter with 24-month warranty.

KM-Multi 12C

Latest top of the range 12 inch model from Onwa Marine with a fantastic new optically bonded 1024 x 768 resolution screen and NMEA2000 data. The KM-12C and its 8 inch sibling, KM-8C, are Onwa’s new flagship chart plotter products. These high end plotters come with a built in 600/1000 Watt sounder/fish-finder and a plastic 600 Watt transducer is supplied as standard. An AIS transceiver or/and an Onwa Radar can be added at any time; it’s plug and play to do in both cases. For the radar, all the controls for the radar antenna and the dedicated radar screens are already built into the KM-plotter. Once the radar signal is present, the KM-plotter becomes a fully fledged radar set with the choice of a conventional radar screen or have the radar trace overlaid onto the chart. Overlaid makes sense of all those mysterious wisps of radar trace when they are overlaid onto the chart itself.

Some additional notable features:

1024 x 768 optically bonded display
NMEA 2000 and 0183 Plus the latest NMEA ONENET
Built-in Radar function (requires Radar antenna) KM displays a dedicated conventional Radar screen and also as the radar trace overlaid onto the chart.IPX6 water protection
HDMI option (specify when ordering)
Can use K-charts 2 & 3.2, C-Map Max and Navionics +
SD card system updates
Can display gauges (engine etc.)
600 Watt (dual frequency) or 1000 Watt (choice of frequencies)

A new feature to Onwa plotters is the move to NMEA2000 as a data transfer method whilst still retaining NMEA0183 functionality so as to be compatible with other 0183 equipment. Not content to move just from NMEA0183 to embrace NMEA2000, the Onwa design team have gone another step forward and introduced the latest NMEA networking protocol, NMEA OneNet as well. One Net is the very latest NMEA IP based network data transfer system – it is the future for data transfer. Read about OneNet in our blog.
