When I bought my boat it came with all the electronics but no handbooks. Recently on an electrical refit, I cut through the coaxial cable that connects the unit to the transducer, eagle magna lll. I have soldered the cable back together, but am having a lot of interference on the unit ( many blank lines on the screen ) making it virtually unreadable. The cable is very thin, much thinner than normal coax. Anybody know where I can get spares from? My local chandlers aren't much help, just want to sell me a new one, but the unit itself was working well before this. Tried ebay etc. Idealy I would like a new cable with connections. Any help appreciated.
