Proper Maintenance for Humminbird

Your Humminbird unit is designed to provide years of trouble free operation with virtually no maintenance.  Follow these simple procedures to ensure your Humminbird continues to deliver top performance.

  • When cleaning the LCD protective lens, we recommend that you first use a solution of warm mild soapy water (like a non-abrasive liquid hand soap or Dawn liquid dishwashing soap), wipe the face dry and if water spots remain, use a solution of water and vinegar.  Always use a soft cloth.
  • Do not use a commercial chemical glass cleaner on the lens. There are several layers of special coatings to ensure your unit has good visibility in daylight.  Chemicals can destroy these coatings and in older models, the solution may cause cracking in the lens of the unit.
  • If the unit comes into contact with salt spray simply wipe the affected surfaces with a cloth dampened in fresh water.
  • Do not spray wash your Humminbird or run through a car wash 
  • Do not wipe while dirt or grease on the lens. Be careful to avoid scratching the lens.  
  • Chemicals like sunscreen and bug spray can cause permanent damage to the special coatings on your protective lens.  This is not covered by warranty.   
  • If your boat remains in the water for long periods of time, algae and other marine growth can reduce the effectiveness of the transducer. Periodically clean the face of the transducer with liquid detergent. Pivoting the transducer up in the bracket may allow better access for inspection or cleaning. 
  • If your boat remains out of the water for a long period of time, it may take some time to wet the transducer when returned to the water. Small air bubbles can cling to the surface of the transducer  and interfere with proper operation. These bubbles dissipate with time, or you can wipe the face of  the transducer with your fingers after the transducer is in the water. 
  • NEVER leave your unit in a closed vehicle or trunk - the extremely high temperatures generated in hot weather can damage to the electronics.
  • Screen Protectors - screen protectors can be installed.  Since these are third party purchases, we are not responsible for the warranty on these protectors and we do not pay for replacement of these protectors if the need arises to replace the front housing, glass bonded display or head unit.
