Vibratory drywasher AZO''s: Metal Detecting Gold ...
Mar 03, 2006· As for which type of rig (drywashers), I prefer the bellows type (Mexican) with a gasoline engine for power. However the gold buddy mid size works well also. for sluicing, I prefer a long tom, carpet floor, louvered expanded metal over that, and angled angle iron riffles, especially in areas that have massive amount of black sand.
