These units are Gen 1 and I have the original boxes and manuals. They have not been used in over two years because I'm too old and weak to get my boat out. Neither of the units have been used much since I bought them. They both have side and down scan transducers. The 7 has the trolling motor mount and the 8 has the transom mount. Both also come with RAM mounts. One is console mount and the other is floor mount. I have about $1500 or so in these units and would like to get $750 for the pair. If you have any questions, please PM me. Thanks for looking!!
