Entry-level package with log and echo sounder transducer type GST43 and GDT43 as well as the Garmin GNX20 instrument as a display.
Quick and easy replacement – even underwater: The Garmin TH43 transducers fit into the TH43 through-hull fittings of existing Silva and Nexus systems.
Simply plug it in and you're done – no drilling, laminating or filling required!
Expandable at any time:
The entry-level packages can easily be expanded at any time via the NMEA2000 network to include additional Garmin instruments, sensors or chartplotters.
It is also possible to connect the GNX packages to existing Silva Nexus or Nexus systems (NX, NX2, NXR) using the Garmin-Nexus Box GND10.
