Wow I have an HDS7 touch with side scan and I have not mastered the side imaging yet. Those are incredible shots. I guess I need to go out without any rods and play with the side scan. There is a huge retainer wall (20'H x 80"L) in Lake Murray in about 60 FOW that I would love to find, but I can't see it on my SI. I need some help I guess. I know the area it is in, but danged if I can find it. I found it years ago with a flasher unit of all things, but that was before GPS units were available. A friend who is a SCUBA diver found it and told me about it.
