What to do if my Hondex Marine Equipment power cannot be turned ON?

  Heather CopelandAug 17, 2025
  If your Hondex Marine Equipment won't turn on, there are several potential causes. The battery voltage may be lower than the standard 11V, in which case you should recharge the battery. There might be a poor connection of the power connector, so retighten it, remove any rust or dust, and replace it if corroded; also, consider replacing the power cable or the connector on the unit. Ensure the power is connected with the correct polarity (+ and -). A cut wire inside the power cable would require a new power cable. Finally, a blown fuse will require sending the unit in for repair.

Why is there too much noise on my Hondex Marine Equipment?
- P
  Paul JohnsonAug 20, 2025
  If you're experiencing too much noise with your Hondex Marine Equipment, it could be due to several reasons. One possibility is that the sensitivity is set too high; in this case, lower the sensitivity or set it to auto gain control. Another cause might be interference from another vessel's echo sounder, which should disappear once the other vessel moves away. Engine noise can also be a factor, so try changing the routing of cables such as transducer and power cables, keeping them as far from the engine as possible.

  If the bottom or fish school is not displayed well on your Hondex Marine Equipment, it could be due to several factors. Check if the sensitivity is too low, and if so, increase it or set it to auto gain. Also, inspect the transducer surface for any rubbish or weed, and clean the bottom or exchange the liquid if dirty. If the clutter is too high, activate low reflection color.

What to do if the image does not appear sometimes on Hondex Marine Equipment?

  Cynthia VelezAug 26, 2025
  If the image on your Hondex Marine Equipment doesn't appear sometimes, ensure that the transducer is sufficiently immersed in the water by adjusting its installation. Also, check the installation of the transducer for any issues that might be causing air bubbles, especially when the vessel is speeding. The issue may also be caused by influence from other vessels causing air bubbles; try moving to another location or wait until the air bubbles disappear.

  If the bottom or fish cannot be displayed at all on your Hondex Marine Equipment, check the transducer connector for any contact issues, retightening the connection, removing any rust or dust, and replacing it if corroded. Also, you can exchange the transducer or send it for repair. Ensure the transducer is immersed enough into the water by adjusting the installation. If there is not enough internal liquid inside the case, add enough liquid to immerse the transducer.

  If your Hondex Marine Equipment is not indicating the latitude/longitude of your own vessel, check the GPS antenna and cable to ensure they are functioning correctly. If you are using an external GPS receiver, verify the data output (GGA) setting on the GPS receiver. If the number of received satellites is low (0-3), wait for approximately 5-30 minutes for better reception.
