Humminbird 898c SI Combo no LH side scan or down imaging

[catchncrisco]

Help me figure this one out guys... My year old 898c SI combo was working fine last trip, used it this weekend and no LH side scan or down imaging. I have the standard XHS transducer and a XNT 9 for high speed depth readings. Have not changed any settings, the set up screens checked correctly, am running the current 5.7 update...any ideas before I return it to Humminbird ????????

Have you changed anything on your boat that would affect the left Si Sonar?

If not, try testing your 898c Si unit on another boat that is running Humminbird Si sonar (any model will do or try testing their unit on your boat and transducer. It may be that the left Si element in the transducer went bad and not the unit. Testing it this way will show where the problem is and will help speed up getting it fixed.
