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
  • Wash the transducer and wipe with a clean cloth after abrasion
