Will any 12 pin transducer work as an upgrade ? Not entirely satisfied with the GT 30 that came with it. Thought maybe a GT 50 or another 12 pin transducer would up performance. Tried to do research on Garmins webpage but when selecting compatible devices page. The message I get is there are no compatible devices. This comes up regardless of item selected.
This is being contemplated for use on a GPSMAP 1040 XS.
