Kenny,
Sorry but had a doctor appointment Friday and another busy weekend. Classes this morning so I’m only getting to check this forum during lunch.

Try this: go to the Sonar menu tab and look for the Transducer Select menu setting. Make sure that it is on the Hi-Def Sidescan setting. It sounds like it is on the Sidescan setting which is for using the original Si transducer that had the 455/262kHz Si sonar.
