Expanded mesh what is the right way

Agree with you on that one. I utilise woven wire mesh on my dredge including the opening that seperates understage of sluice. When I did this my fine gold recovery went up.

By doing this it creates drag on the water column and allows heavies to drop out into understage sluice while at the same time letting more water flow into the understage.

Keene is offering this upgrade on all of their 3 stage sluices with this concept , as well as rolling out this philosophy into the super max dredge.
