Soner temp readings

[Turkeyman]

I have an HDS 5 that used to show water temp, now just black lines, I changed out transducers to another one I had that works on an old c103 unit, but will not show anything on the HDS. I can get water temp if I switch to SS. Any ideas? Do I need a new transducer?

There are times when the unit doesn't read the digital temp reading on your screens. You can try to delete from the Overlay Data the temperature reading and then cycle the unit from off to on. Then when you power up the unit, go to Edit Overlay Data and select the water temperature reading again for display on your screen. Sometimes this will correct the issue. If this does't fix you issue, you can change the "Global" setting for the water temp to "Local". You can find this under "Scope" in the menu.
