Has anyone used the McKirk Bucket Grizzly? Thinking of purchasing one for the field. My first question is how well does it stay on top of the typical bucket? Once your shoveling I'm guessing that the bucket/grizzly is somewhat unsteady. But as you go it must become stable. I see the disadvantage of yet another piece of equipment to carry into the field. But time is money and if it makes classifying easier what the heck. Your comments please.
 

Classifying is best done wet so the little bits of gold wash off the bigger rocks they are stuck to. I would only use that classifier when dry washing personally. (Which I don't do since I'm in Colorado)
 

Carry a 7.5 & 5gal bucket. Classifier goes on 7.5 (which is taller) and 5 gal collects tailings. Start with water in the 5 gal and after several shovelings, spin the 5 gal and dump in into the classifier. Refill with water and continue.

Slightly more weight, use another 5 gal bucket (or a 2.5) as a bucket classifier. Put it in the 5 gal collecting tailings and leave the 5 gal full of water. Few shovels then spin the classifier backnforth and up/down and dump tailings. When it doesn't set down quite right, dump into classifier and refill with water.

Caveman method:
Drop a tarp. Cross (X) two 2x2s. Unroll a 1/4" (3/8 1/2" whatever you're after) hardware cloth and attach to cross. Lean your cross against your chair and toss shovel fulls at the screen. Fines fall on tarp, stones fall to the front.

...And here I thought the object was to have enough water flow through the sluice that ya didn't need to classify materials before running them. Silly me!

I haven't used the Bucket Grizzly but I've done my share of classifying out in the field. The screen box is a tried and true way of getting it done. I use a smaller one with 4 legs but may have to super size mine soon so I can keep up with the sluice feeder. (aka Robi)

My new box is going to be a big improvement over my old "Long Tom" but I have a feeling that I'm going to have to upgrade the pumps to move more water through it.
 

What Kevincolorado said plus I can see a guy getting real frustrated and po'd everytime it falls over until you have enough weight in it. I really like their stuff, but this one kind of seems like most fishing lures- designed to catch more fisherman then fish.
