[QUOTE="HeadsUp, post: 442368, member: 414"] if you look closely the knudsen and knelson bowls are different One has tiny holes in each riffle and water flows into the grooves from outside to keep the fines stirred up , the gold stays in the groove and gets washed down after the bowl has stopped spinning , the other one is just grooves. They are also made out of a tough rubber , any made from steel would be either very old models or home made. [/QUOTE]
