The Gold Well is being made again with Bernie's blessing out of Boston Massachusetts. See his Gold Well Sluice Facebook page. I would like to talk with you if your still at mining.
I have a 33” drop riffle sluice, made by RPE, extremely lightweight and works great for fine gold. Much cheaper than the Angus McKirk, haven’t compared the two but this one works great and at a price of less than $40 it’s much easier on the wallet. Just thought I’d share
I use a Caledonian classic sluicebox. A very popular and best-selling ramp in Europe. I found a great article on a French gold panning site. https://www.goldlineorpaillage.fr/sluice-box-rampe-caledonian/
In addition they put a very practical site translator at the top of the page.
