[QUOTE="WalnLiz, post: 101031, member: 147"] For gemstones the strait sided mesh works best and when rocked prevents the sapphires from moving down the mesh. It does however have a negative side in severe ironstone areas as it will tend to hold these up as well. The biggest problem with most people using catwalk for gold only is they put carpet or matting under it. This will only cause clogging of ironstone and not allow the gold to creep under the ironstone "freely" from directly beyond the slick plate. The ironstone in the catwalk is meant to act like a maize of marbles allowing the gold to slide "freely" beneath the ironstone. If one has a lot of Spinel and sapphires in the area the strait sided will hold these up the same as ironstone as they have similar Specific gravities. [/QUOTE]
