Not familiar with this particular unit but a miller table is great for cleaning your cons once classified way down and taking your time to spoon feed it......... and Washington has lot's of fine gold. Unfortunately that's about all we have.
Do a search for DIY or home made miller tables. Cheap and easy to build.
Miller table's are tried and true and a great option. In an effort to reduce prospecting equipment and cost, I am currently looking into some custom Gold Hog washer matting for my mini banker, which is a fraction of the price (thanks arizau for the idea). All I need to do is set up my mini banker as a recirculator, add the washer mat and process my cons to a super concentrate. From there I don't mind using a finishing pan. If that doesn't pan out then I'll look back into miller tables.
I use my miller table mainly for the finest of fine gold, like for -100 mixed with fine black sand when I go to the coast with my Gold Cube. That stuff is extremely hard to pan clean.
I built a 2.5" dredge this winter that has Gold Hog mat in it. I'll probably pan the big 50+ stuff and then everything smaller will go on the table. My table has chalk board paint on it right now, but I bought a roll of rubber mat to put in it that is the same as what's in the black magic clean up sluice to see if it works even better and faster.
I was thinking about making a miller table....either recycle a piece of actual chalkboard or pick up a hobbico mat.
Would like to know you results echo...as I am not a fan of the extra work to classify down my material.
I have 26 yrs as a machinist and tool designer. ....hope I can fab up something halfway decent. My problem is my perfectionist trait.
Hope to see pics of what you guys come up with
