The transducer is a sensor that transmits and receives sound
waves into the water.
• Fit the transom transducer supplied, following the
instructions in the Transducer Installation Manual supplied
with the chart plotter.
• In case of installation of 50/200 kHz transducer, water
speed sensor and water temperature sensor, an optional
through hull dual frequency sonar transducer and through
hull speed/temperature transducer provide more enhanced
performance. Contact GME for more information.
• Connect the transducer to the G142FD.
If you use Y-cable, the fishfinder can display water
temperature and water speed from the compatible devices and
receive and display the depth from transducer. To connect the
cable to the unit
see picture right.
