KP-25X

This model has everything built in - with both Class B+ AIS and sounder/fishfinder. All these features in one small box, how do they manage to do this? Well, years of practice is the answer.

 Whilst the 'big name' manufactures have been producing basic chart plotters, Onwa have been producing plotters with AIS transceivers built-in since 2014. Over the years they have just got better and better and the ultimate result is the X version with not only 5 Watt Class B+ AIS but also with a built in 600 Watt Sonar/Sounder fish-finder.

All Onwa AIS transceivers are the latest Class B+ 5-Watt version with the same SOTDMA technology as Class A commercial vessels although at reduced power (Class A being 12,5 Watts). SOTDMA technology has advantages in performance over the older CSTDMA providing faster access to AIS transmission slots and higher power. If you are researching AIS transmitters you will find that some manufacturers are still offering old Class B CSTDMA transmitters and they will likely be more expensive than Onwa products using the very latest version.

X version has NMEA0183 and NMEA2000. For Wi-Fi add an NMEA to wi-fi converter. See our YakBitz 0183 to wi-Fi converter or our Onwa 0183/2000/wi-fi converter. If you are thinking of using an iPad or phone for Navionics/Garmin Boating App (or similar), message or call as we have lots of experience with this product and lots of satisfied customers using it.
