I have a Furuno LS6000 FF I took off my boat and added a new Furuno so I am reusing the transducer and pwr. cable.It worked great when I removed it.

I also have a Blue Seas battery switch I just took out and replaced with a BEP cluster.It is only 2 years old and works great.

Furuno LS6000 $75
Battery Switch $25
If interested give me a call 610-405-8817 Thanks,Anthony
