Classification is the Key to Fine Gold Recovery. It is well-established that if you want to effectively recover finer particles of gold, you must first separate them from the larger-sized materials which are being washed through your recovery system by a higher-velocity flow of water.
A dredge is basically a suction hose powered by a pump and attached to a sluice box, usually floating on a tube or pontoons. The suction hose acts like a large vacuum cleaner to extract material from the bottom of a stream or pond and deliver it to a sluice box usually floating on the surface of the water.
5" Dredge. Our 5" size always has been popular with dredgers who were looking for the perfect balance of portability with higher productivity. Smaller dredges simply can't process as much gravel and the larger dredges require more effort to get into those more remote areas where the richer gold deposits are.
2" Dredge/Highbanker Combo. Beginners love our 2" machines because they are small, lightweight and very affordable. The Proline 2" combo offers the versatility of being operated as either a 2" dredge or a small highbanker which can be fed continuously with a small shovel.
