Took this unit off my boat earlier this spring. Only have head unit, no transducer or gps puck. Works great, couldn't pull lines, stripped cords when i did, was huge pain in ace, so just wound up cutting everything and tossing cords. Reason i took out is I upgraded to a humminbird 997si/di.180 shipped obo. Can buy power cable and transducer on ebay for $90 thanks
