If you had one choice what would you buy or use to process cons for fine gold? I do understand classification has a big part in this. I have used the blue bowl, bucket sluice and a few diy projects. Also does the spiral wheel work? I thought of building a shaker table. I just wish someone made a shaker table for a small guy. I can not justify spending that type of money for something I would use maybe 1to2 times a year when I go on vacation from FL at GA.
