My first testing of my home made high banker/Dredge. This is an amazing tool. Now I can dig in the high bank river gravels and instead of digging up a couple shovels of clay. With the Hydro Force, I can get to the clay and suck the gold up off it. I was excited to see that when I checked the gravels that washed out of my sluice box, there were only a couple specs of Micron gold that washed down. 99% recovery. I don’t know of anyone else’s sluice box that can guarantee that. Come visit the Wild Ammonoosuc River. I am a gold prospecting guide. Be it dredging, panning or high banking. I will put you on some gold guaranteed. Check out my facebook page to see more pictures of the gold I have been finding. Yankee Gold Prospecting New England, on facebook. If you decide to go gold prospecting and want to spend a great weekend on the river. Stop in to the Twin Rivers Campground, in Bath NH. They own the lower mile on the Wild Ammonoosuc. A great family & frinds get away. See you on the river. Jim
