Still nothing on the graph. Reset to factory default and no change. I didn't think it would help since I haven't touched any settings in quite some time. It was working fine for the first three hours on the water, then nothing. I didn't bang the transducer on anything, no twist or cuts in transducer cable. The unit is just 13 months old. Question: can I hook my 998 up to the di transducer to check it out to see if a head unit issue or transducer issue?
