By adding this New Classifying Screen system, you can now take an ordinary sluice box and turn it into a High Production sluice that requires no pre-classification, allowing you to recover even more fine gold. The addition of this screen will allow you to easily double production with less effort. You can shovel bank run material directly into the sluice box, or even dump buckets of bank run material. The screen system features a mix of grizzly bars, a punch plate and woven wire that quickly classifies the material and drops the water speed underneath to at least half, allowing the riffles to do their job in ideal conditions.
Some drilling & assembly required
