Made a English version rocker box but ran out of time to keep playing in the creeks with it

I don't know what to say, that's strange. Must be hunting for nuggets or reasonably sized gemstones?
Seems seriously inefficient. Although in saying that labour costs are probably not a major issue.

It is obviously not a sluice box - no sluicing is involved. It appears to be hand-picking of a coarse sieve fraction on a conveyor belt, presumably the coarse fraction from something like a sluicing operation. But water does not seem to be part of the process shown (although it may have been used off-screen to get the gravel spread out on the conveyor belts.

Seems to be something someone simply posted elsewhere with that title. However, it does look effective for hand picking, although I would not want to be dependent on that process alone to work gold (assuming gold is the target).

I think they are picking rubbish out of at least two sizes of washed river gravel.
