The YakBitz Yakker 2 Port Multiplexer combines the NMEA 0183 data 2 devices such as Fish Finder/GPS/Chart Plotter/AIS Receiver etc and sends it to your Wifi enabled Phone/Tablet/PC.
This enables navigation software like iNavx, Navionics Boating, OpenCPN, Memory Map etc to use your depth, location, wind, speed and other data.

You can also connect Yakker to your own WiFi network so your WiFi devices stay connected to the network AND receive NMEA data.

Supports both UDP and TCP protocols.

In addition, you can adjust the transmit power of the Yakker enabling you to reduce power if it's positioned close to your router.
