Transducer Maintenance

How to Abrade the Transducer

Please watch this short video before abrading your transducer.


  • Abrade the top surface of the transducer (shown in green on the image below).
  • Never polish the lower surfaces of the transducer (shown in purple on the image below) – this will result in damage to the sensor and failure of the transducer.


  • Be cautious to ensure the abrasion block remains horizontal to the surface.
  • Only abrade the transducer once housed in the sensor body.
  • Use a new piece of abrasion paper for each abrasion.

How to Replace the Transducer

Please watch this short video before replacing your transducer.

Always ensure the sensor is dry before removing the transducer.
  • Remove the 2 screws holding the Clip in place and remove the Clip.
  • Using the provided bottle opener – pry the sensor upwards, it will raise about 15mm.
  • Pull the transducer out.
  • Apply a small amount of grease to the perimeter of the new transducer.
  • Align the new transducer with the key and push until the lower edge is flush with the main body of the sensor.
  • Reattach the Clip using the 2 screws provided.
