An improved design over the old standard Keene prospecting classifier screens and sieves, this new classifier screen design is very clean with no need for screws or silicon to attach the stainless steel screen to the plastic housing. They also have superior UV protection and will not crack easily when left out in freezing weather.

These rock and gravel classifier screens are made of tough, high-impact plastic and stainless steel mesh screens. Designed to fit in the top of 5 gallon plastic buckets and over most gold pans, they are very easy to use. A must-have tool for the rock hound or gem and gold panner.

Classifier's overall height is 3 1/2 inches. It's been carefully designed to allow up to four classifiers to be nested together with an overall height of only 6 1/2 inches. These are very compact sieves and easily transported.

We recommend using a combination of at least 2 LARGE MESH sieves on the river and ideally a combination of the next 5 sizes when cleaning up your gold concentrates. A discount is available for the set of five and all Nine. Classifiers stack one on top of the other easily so you can classify your material down to the ideal size for easy and very efficient gold panning.
