I have a Humminbird Helix 9 with down imaging and gps. It comes with the transducer and power cord. I also have a trolling motor mount for the transducer. It was only used for a year. I bought a new boat and it came with Lowrance Units. I am missing the Gimbal mount for it.(I accidentally left it on my old boat.) You can find them online for $40. I'll also leave the Navionics hot maps chip in it. First $550 takes it.
