Rugged but lightweight this product is specially made for us to provide a deep vee

rubberized mat tough enough to stand up to the rigors of prospecting but thin enough to

not require special applications. The overall height of the mat is 150/1000th of an inch

and the depth of the grove is 110/1000th of an inch

The ideal matting for easy identification of gold values due to the contrast of gold on black. Immediately see the gold that has been trapped by this matting right in the sluice! Also Great under the Miners Moss for better Fine Gold Recovery.
