Question about F/F

In the picture below is the fish actually at 4 & 5' fow.

I have transducer on trolling motor,about 1' in the water.

I thought someone told me that I had to add or subtract some off of what is displayed.Any help is appreciated as this is my 1st ever toy like this :eek:

If your xducer is 1' below the surface of the water then the fish at 4' are actually 5' below the surface. Most modern DFs have a setting you can compensate for the xducer depth. Its called keel offset or transducer offset.

Thanks IBNFISHN I did recall seeing that keel stuff (didnt touch it as didnt know what it was) I will try to learn how to get it to show actually reading.

Thanks again as I didnt even know this could be done.
