Simrad SH40 Fish Finding Sonar

Cleaning the sonar transducer

The transducer normally needs little attention. However, the transducer face must be inspected and cleaned when docking.


  1. Place the vessel in dry dock.
  2. Ensure that the distance between the vessel hull and the bottom of the dry dock is sufficient to lower the transducer.
  3. Lower the transducer.
  4. Perform a thorough check of the transducer. If necessary, clean the transducer.
  5. Once inspection and cleaning has been done, hoist the transducer up into the trunk.

Refer to your user manual for a more detailed procedure.
