Backpack Screen (17" x 22"), 1/4" Polyethylene Screen

For back country surveying we offer removable, lightweight, metal alloy backpack frames mounted on small rocking sifters. Total weight is less than 16 pounds. A removable nylon carrying mesh over the sifter box is a standard feature so the sifter box can be used to carry equipment, such as tarps, into the field. All wood is hand graded for minimum weight.

Note: Backpack Screen features the same screen area as our Small Rocking Sifter but, in order to minimize weight, does not have the front lateral dowel and is slightly shorter in height.

Our polyethylene mesh screens are specifically designed to assist in the recovery of sensitive law enforcement evidence or delicate artifacts. Polyethylene mesh minimizes abrasion of bullet casings and helps prevent damage to fragile ceramics and bone. Because polyethylene mesh does not offer the same load-bearing ability as steel mesh, we offer a high-density plastic strapping for reinforcement. Simply choose “Plastic Strapping” (item No. PSTRP) under our Optional Screen Features.
