My version of a sluice

Made mine out of a plastic drain grate - different manufacturer than "Reeks" model. ( Flat inside bottom)
I cut the top edges off the side walls and a couple of inches off each end to create the channel.
I put a short timber handle at one end for carrying and also hold down the galvanised funnel. ( I folded the myself)
Then I fitted an aluminium plate to lock in the funnel.
I used a small ribbed rubber mat for the base to catch the fine gold. No baffles or mesh used.
To direct the water down onto the ribbed rubber mat I clamped a section of rubber strip to lay on top.
I am after the small gold that others may lose.
Hope this offers some help to others.

That looks very portable. Good job mate. Does it work well?

Yes BeagleBoy, it does a good job. Just a matter of controlling the water flow. This depends on the angle of drop plus speed of water. Using it without the funnel will slow the flow.

Nice job thanks for sharing your ideas
