I have used the Gold Cube in Alaska for the last 3 years. I love the speed at which you can put your material through it. I first classify my material down to a 12 Mesh before running it through. I use a 4 stack because you will get an occasional flake making it's way though the first 3 trays, but it is a very minor thing as the Gold Cube is very efficient.
I had sold my Gold Cube in Alaska to another miner and now have bought a 2nd one for myself. I noticed that the cube I received had the older style connector and hose coming from the pump to the slick plate than the one shown in the picture. Not a problem at all but the picture should reflect what you will receive. You will enjoy your Gold Cube.
Works great! Compact footprint and fairly easy to set up. Amazing the speed you can process material and turn a bunch of buckets to a couple cups of cons and finish from there.
