If that is the teardrop shaped transducer than it is the correct one riverrat.
Did you ever call the Humminbird Customer Resource Center folks?
That picture you posted doesn’t point to any particular problem so the fault could be in the unit or in the transducer. If you can: test your 597ci HD DI unit on someone else’s boat that has a Humminbird DI model unit on it. If not, you may have to send the unit and transducer in to be sure it gets fixed.

I have not contacted humminbird yet. I think i may just cut my losses with this unit and trash it. This unit cost more than it helped. Hope my new 998 doesnt disappoint as this one did.
