I'm selling my Gold Cube because it's setting in my basement taking up space and not being used. It is a 3 stack deluxe and works very well! It's a concentrate clean up device. If you dredge for gold you get lots of concentrate after awhile. If you pan your concentrate before hand and pick out the bigger pieces (anything above 1/8 inch) the Gold Cube will do the rest. It is capable of going through 1000 lbs per hour! Most of us dont have that kind of concentrate setting around but it will quickly go through whatever you have. It can concentrate 1000 lbs down to 1lb with 99% of the gold caught. You'll have to buy another tray for the extra 1% I didnt think and extra tray was worth the extra $99.00 for just catching 1% of the gold.
Here is a youtube video of it in action with 1000 lbs http://www.youtube.com/watch?v=wUlNNIxKjaQ
It is $389.95 brand new. Im selling mine for $350.00 (not including shipping) because it hasnt been used but twice and it's in new condition. It's a little dirty but that will be cleaned up before shipping. I live in Pendleton County WV and can bring it to you if you dont live too far away (> 4 hours). Hell i'll even show you how it works if you have concentrate.
It comes with:
• One Slick Plate
• Two Separator Trays
• Hose Adapter
