Before I throw out my two HDS 12 gen 3s and associated transducers, if anyone needs any of this for parts, just message me.

All the xducrs were changed within the last <2 years and everything was working when I pulled it.   Apparently, the epoxy never set on the thru hull when I changed it, I think they only shipped we one part, and it popped up and so I thought it had gone bad again, but is OK.   There's the TM xducr for side scan, and the two for the other unit, the thru hull and big side scan.   There's a fusion stereo unit that works.   All this stuff is ten years old and long out of L service.   

Going to trash today.
