Cleaning the Sensor

You need to regularly clean the sensor for proper performance.

Wash the sensor with fresh water and dry it before you charge or store it.

Regularly check that the sensor is clean. If not:
  • Wash away mud or debris with warm water.
  • Use Isopropyl alcohol to clean the end cap and transducer. Use a steel wool pencil to clean the shoulder bolts, and very fine sandpaper (180 grit) to clean between them.
    Notice: Do not use highly abrasive materials or jet wash.
    Notice: Special care should be taken with sensors and components sensitive to mechanical shock or contamination.

Regularly check the state of the shoulder bolts on the end cap and clean them using a swab or Q-tip with Isopropyl alcohol. Fully clean the surface from debris and inspect the surface for burrs or pitting.

Regularly clean the pull cord magnet or it may stop working:
  • A hole on the side of the NX housing allows you to clean the magnet assembly. Use a water jet or an air blower to remove any sand that may have accumulated around the magnet.

  • If needed, remove the metal disk fixed on the housing and clean the magnet with a swab or Q-tip. See Replacing the Catch Magnet or Cords to know how to remove the components.
