What to do if my Humminbird Fish Finder doesn't detect fish, even when they are in the water?

  The sonar readings may be affected by several factors. The transducer might not be positioned correctly or there could be mechanical interference. The transducer may be mounted at an angle, or the hull may be too thick for proper sonar transmission. Also, the bond between the transducer and the hull might not be airtight, or the transducer could be dirty. Low battery voltage or electrical noise from the boat's engine can also interfere with sonar reception. Adjust the transducer position, ensure it's clean, and check for electrical noise.

  Confirm that the power cable is properly connected to the control head, wired correctly, and the fuse is working. Ensure the battery voltage at the power connector is at least 10 Volts. Correct any issues, such as removing corrosion from battery terminals or wiring, or replace the battery if needed.

Why does my Humminbird HELIX 12 Fish Finder control head lose power at high speeds?
- J
  Jasmine CastilloAug 9, 2025
  If your boat's engine has unregulated power output, the Humminbird Fish Finder control head might be using its over-voltage protection feature. Ensure the input voltage doesn't go over 20 Volts.

What to do if the bottom disappears or weakens at higher speeds on my Humminbird HELIX 12 Fish Finder?

  Robert LarsonAug 15, 2025
  The transducer position may need adjustment. A mix of air and water flowing around the transducer (cavitation) can interfere with sonar data interpretation. Also, electrical noise from the boat’s engine might interfere with sonar reception. Adjust the transducer position.

What to do if my Humminbird HELIX 12 control head doesn’t detect a connected accessory?
- E
  Ethan GambleAug 20, 2025
  First, check that the accessory cable is securely connected to the control head; reconnect it if necessary. Next, confirm that the accessory is connected to a stable and reliable power source. As a last resort, power off all control heads and connected equipment, wait 10 seconds, and then power everything back on.
