this box will drop in to a standard A-52 style box

Drop riffle sluice boxes are used a bit differently than the old style Hungarian riffle sluice boxes!

Your goal when running a drop riffle sluice box is to run the box as flat as possible. Without ever having sand just sit on the slick plates between the riffles. The flatter you run the box the better the recovery rate on fine gold.

Water flow on drop riffle sluice boxes needs to be a bit more than the old style boxes due to the flatter angle. Watch the sand in the riffles...when you have the proper water flow this sand will be dancing around within the riffle.Do not try to adjust the box to run the riffles clean! The heavy material within the riffles works much like jig shot which allows the gold and heavies fall through the suspended material and the lighter material just floats right past.
