I have 2 humminbird 597 CiHdDi gps combos in excellent condition. One has a trolling motor mount transducer, the other has a transom mount. There is a spare transom mount as well. One of the transducers is new never used. There are no marks or scratches on the units. This is a paypal auction only & shipping to lower 48 states only. No international shipping. I will ship priority mail with insurance.
