How to Troubleshoot No Depth Reading on a Fish or Depth Finder

There are a lot of things that can cause an issue with your sonar unit to cause it not to read depth.  It can be anything from a loose connection, bad transducer or unit, or a bad cable.  There are many ways to troubleshoot this issue.  The easiest thing is to take a second unit from another location on your boat and try it on the transducer that isn't working.  If you don't have another unit on your boat see if you can borrow a friends unit.

Take a look at this video for more detailed tips on how to troubleshoot a sonar unit that isn't reading depth.


This video shows a Lowrance unit but this procedure will work on Simrad, Humminbird, Garmin, Furuno, Vexilar, MarCum or any other brand of sonar units.
