I70 depth readings not true

Thanks Chuck,

The boat does have my old transducer but it is completely unplugged. I left it in there as a back up if I ever needed it but it has no power and is not connected to anything. I did call your tech support line while waiting for this post to get uploaded to the forum. Your colleague suggested I unplug the bare (ground) wire coming from the transducer to the ITC5. He said sometimes noise comes for the ground. He asked me to see if that clears up the problem but to also watch my temp and speed to make sure they are still behaving.

I will follow your suggestion and turn off all instruments and the chart plotter to see if that clears up the issue before unplugging the ground.

Sound like a plan?

Many thanks for your support.
