tis my little tub and sluice i use for puddling clays works well with some elbow grease,handle at the back is to tip the tub once all the clays have been broken down.
The steel pipe with the hose connected is in a X pattern at the base with 4mm holes drilled on the base and sides a 6.5hp 40mm fire fighting pumd supplys the right amount of water (at half revs) to keep enough water over the riffles.I usually tip the tub (which is hinged to the sluice) and then manually remove the fines and put them through my wash plant to seperate the heavies(that pic is in another section of the forum....oooops...)
