I have a Furuno FCV600L and a GP37 with the GPS019 pole mount gps antenna that I removed from a boat when updating the equipment. There is no transducer with the fish finder, but they are readily available in whatever style you need. Yep, the stuff is a little old, but it is in very good shape and I have bench tested them, they work perfectly.
$400 for the FCV-600L, brand new is about $800
$250 for the GP-37, brand new is about $500
or you can have both for $600
