Latest KM 8 and 12 inch models
Released in 2022, these brand new multi-functional plotters have embraced new technology and now include the new NMEA OneNet data transfer system
New Generation KP1299 12.1" plotters
Released May 2020 these are the third generation of the 1299 series and available in four versions:
KP-1299X this is the top of the Onwa range and it has every thing in one unit:
- Multi-function 12.1" IPX6 chart plotter
- SO-TDMA Class B+ AIS transceiver
- Built in sounder/Fish-Finder with up to 1kW capability. Comes with a more than adequate 600 watt transducer (1kW transducer available although this is more suitable for professional use).
- Ready to connect to an Onwa radar either by cable or by wi-fi
- Comes with 600 plastic transducer as standard (upgrades available).
KP1299A
- Multi-function 12.1" IPX6 chart plotter
- SOTDMA Class B+ AIS transceiver
- External 1 Kw KM-Sounder/Fish-Finder can be added
- Ready to connect to an Onwa radar either by cable or by wi-fi
KP-1299C
- Multi-function 12.1" IPX6 chart plotter
- Built in sounder/Fish-Finder with up to 1kW capability . Comes with a more than adequate 600 watt transducer (1kW transducer available although this is more suitable for professional use).
- External K-200A AIS transceiver can be added or a data feed from an AIS source will transform the 1299C to a fully functioning AIS receiver with user configurable collision alarms.
- Ready to connect to an Onwa radar either by cable or by wi-fi
KP1299
- Multi-function 12.1" IPX6 chart plotter
- External K-200A AIS transceiver can be added
- External KM-Sounder/Fish-Finder can be added
- Ready to connect to an Onwa radar either by cable or by wi-fi
Note, Onwa X Band radar sets are designed for commercial use and are widely used by professionals mariners in Asia. The performance is considerably better than radars produced for leisure sailors For example, the 60 cm Radome KRA-1007 has a horizontal beam width of just 4 0 degrees - compare that to leisure radars where this is likely to be much greater (think of beam width as focus).
Radar display can be overlaid onto the chart screen - perfect for those of us who want a clear and easy way to interpret the radar targets.
KRA-1007 Radar can be connected via conventional cable or by Wi-Fi
Just a mention on the Radome - it is quite heavy and probably too large and weighty to mount on a sailing vessel's mast. I have mine on a 3 metre pole on the stern quarter of my 28' sailing boat and it works great.
Frequently asked question: Why is the Radome 60cm, other makes are smaller?
The size of the transmitting antenna in the dome directly affects the beam width (focus) and the larger the antenna the smaller will be the beam width. It follows that to achieve a small beam width a large antenna is required - hence the size. To illustrate how increasing the size of the transmitting antenna effects the beam width, 55 cm antenna in the 60 cm dome has a horizontal beam width of 4 degrees, a 120 cm open array antenna is 1.9 degrees and 1.8 open array antenna is just 1.2 degrees. Whilst it is true that other make radars for the leisure market do have a smaller Radome - they also have higher beam width figures. It may be worth noting that top of the range Furuno radars also have a 60cm Radome.
New in 2023
KRA-1009
A brand new Radome product specially designed to be used as a networked radar system for use with KP1299 and KM series plotters. This model Radome is smaller and lighter than the 1007 above, making it very suitable for leisure vessels and smaller commercials yet retaining the great Onwa quality. Smaller (50cm dome) and lighter (8.8K), horizontal beam-width 5 degrees.
