Amazon : Royal Gold Dust Concentrating Miller Table ...

Royal is by far the highest quality equipment for the weekend gold miner. This was the first idem I have purchased from Royal. Very happy with the quality, packing, instructions, and the video included. I proses my fine gold inside, thru the winter, so I did purchase a 110 volt pump to keep the water flow more consistent. Thank you Royal.
