Any experts on the C-80 / DSM-250 on the board or had this problem:
I have a Raymarine C-80 MFD and a Raymarine DSM250 Sounder. The sounder will not lock onto a depth. It will read 21'-some inches for a few minutes act like it is working and I know the water depth is incorrect, then blank out for a few seconds then back to the 21'-some inches. Keeps repeating, Both running and sitting still. Th:helpsmilie: e GPS works fine. No radar. I read the manuals but can't track down the problem. I factory reset the unit but that didn't help.
Any suggestions where to start would be appreciated.
Thanks,:helpsmilie:
