Very low flow sluice design

[Ben78]

Who's got a good design for a lightweight sluice that can be operated off a small bilge pump in areas where there is very low or no flow? Will need to be carried up to a few hundred metres into the scrub. The creeks that I have noted for working don't have large enough waterholes to run a pan at any sort of speed hence looking at a pumped sluice solution. Will need to capture gold and sapphires.

Thanks!

Hi Ben
The Angus Mackirk grubsteak needs very little water flow.
Here's a couple of threads with pic and vid of mine.
In the second thread I have it set up at home with a 750gph bilge pump.
