Check the listing for details. Gold Pan Panning Classifier Mesh Screen Sifter 9 (NINE!) Piece Set! 1/100"-1/2". Condition: New. Listed at 149.99 USD. This is a VERY nice well made NINE PIECE gold pan classifier/sifter set, and has 304 STAINLESS STEEL MESH. You have to be VERY careful with these classifiers! Especially the "economy" and "handmade" models that are being sold on ebay, as the mesh is NOT Stainless, and will RUST in no time. The mesh/wire size varies, see the chart below. You will receive ONE pan of each size. These classifiers fit onto a 5 gallon bucket, and are stackable with the other classifier pans I sell. This means you can classify more than one size at a time. Put on however many pans you have (Biggest mesh on top, of course. Don't laugh, I've seen people do it backwards!) and start shaking. They fit very nicely onto most any 5 gallon buckets. See the second picture. These pans work GREAT to separate gold from the junk! Once you get everything sized, you can pan it much easier, or use a concentrator for the smaller stuff. PLEASE NOTE! I am a gold panner myself, and USE everything I sell. I've belonged to the Desert Gold Diggers here in Tucson since 1995. I've been gold panning since 1986.
