57" long, 12" wide 4" high made in N. California by South Yuba Mining Co. sluice body/flare construction, stiff and strong yet lightweight. Hungarian riffles are 16ga. steel welded onto a 12ga. frame. Expanded metal riffles are 3/4"raised expanded painted black metal-steel, that have a 3/8 vertical drop behind each diamond riffle.Expanded metal is thepreferredriffle system for gold <1mm if prescreened to 1" minus check thisengineeringreport for more info:

Our sluices use black V matting and blue loop unbacked matting that catch fine gold extremely well, much better than carpet. The black assay mat at the start gives you an idea of how much gold you are into in a particular hole you are working from. About half the gold will initially hang up in the black matting so you can gauge when a spot is really rich and when its not. The unbacked blue vinyl loop matting really is the best ive found, lets you have more peace of mind knowing that you wont loose the smaller gold if you disturb your water source or mishandle your sluice. At cleanup you will see that most all of your fine gold will be sitting underneath the blue matting in a black sand layer, trapped by the downward force of the clamped riffle tray. Catches bigger nuggets too, they will most likely just stop on the black matting or in higher flow drop right in one of the diamonds and stay there. Black matting is siliconed in place, also siliconed on edges of black mat to prevent any gold loss. Riffles are welded with side strengtheners and a rear stiffener.

Front flare attached with bolts and detachable, fitting inside sluice for packing in to the creek.
