I am selling 2 Lowrance 7 HDS Gen 1 units. Both units are in great shape. Always removed from boat in winter and stored inside. They come with 2 transom transducers. I am also including the networking cord that connects the two units. I'm selling both units for $700 ($350 each). I'm also selling the Lake Master Michigan Mapping Chips (compatible with the older Lowrance units) for $100 each. These Mapping Chips make the units invaluable. Feel free to email me is you are interested at email@example.com. Sold!
