I would check wiskey pete's on ebay . I gotten some from him and found gold , don't expect much . You will never get more than you paid from any of them .
Beach High Banker, Sweep Jig, Whippet Dry Washer, Lobo ST, 1/2 width 2 tray Gold Cube, numerous pans, rocker box, and home made fluid bed and stream sluices.
Maybe save yourself a few bucks.....If I remember right you have already panned some gold with purchased paydirt (?). If you mix some of the gold you already have with a few gallons of bank run material from the area you are thinking of working, or similar material (gravels, sand,clay, silt and all) then that should give you an indication as to how well the sluice works. Count pieces or weigh what you are adding to make sure what you put in you get out. If you get more out than what you put in then all the better. What ever you do, collect the tailings so you can pan and re recover any gold that may have escaped the sluice.
