[QUOTE="22shells, post: 312075, member: 3817"] Hi madtuna, I've got one and it works quite well- the hard bit is finding rocks with gold in them! I find it works best with rocks about an inch size, (maybe a bit bigger) much bigger and the feed tube can block up. But you can put several inch size rocks in at the same time, so long as it doesn't block. You can hear when it crunches them and then you can put more in. I pre crack bigger rocks with a hammer first. Certainly a lot easier than using a dolly pot. I use mine for rocks with no visible or detectable gold in them, just rocks that look like they might have gold in them, and I have got a bit with it but not as much as sluicing and panning. The machine works well, but I only do a bucket every now and then. If you wanted to do heaps with it a bigger one would probably be better. [/QUOTE]
