So I ordered a new msi+ unit and have moved my helix 9 chirp gps 2d unit to the bow removing my helix 7.
i am now having some severe interference on the bow unit. I have checked the fuse in the head of the ultrex fuse was good but put a new one in it anyways.
the power connection seems good and the tranducer is 3 trips old. The ultrex has the built in transducer which isn’t connected to the unit could this cause a problem?
scambling for ideas to fix the problem.
