Location: Forest Lake, Mn. | Was out today and had my 110c sonar act funny and am not sure what the trouble is. I don't know if it's the transducer or the unit itself.
Here's the symptoms. While in water that I know was 10 deep or much deeper the unit would say that I was in 1 to 2 feet of water and the shallow alarm would come on. The graph display would show only a totally filled screen or the bottom was 2 feet deep. As I said, I've fished this lake and area many times and know I was in water at least 10 feet to 30 feet deep. The GPS Map display was normal and according to that I was over 10 to 30 feet of water.
I would change ping speed, chart speed, sensitivity, turn the unit off and on, change color line, surface clarity control, the advanced signal processing, check connections, anything I could think of to try and get the unit to display normally. After awhile it would just start to read normally again and show a normal display and depth reading with normal bottom display and fish arches,etc. It would change between the abnormal shallow reading and normal for no reason that I could determine. I also looked over the transom to check for weeds or anything that might be caught on the transducer and couldn't see anything.
As I said, all GPS functions,and map display was working normally. So I don't think that it is in the unit itself but suspect the transducer or transducer cable. Does that seem logical to any of you? Has anyone else experienced this? Any suggestions? I hope that I don't have to replace the transducer as that would be a job ripping out the cable and running a new one. So I thought I would ask here first before ripping things apart.
Thanks for any help!!
