Sirchie STT103 SirchTRAK Print-Out Sheets, 10 Pack

To accurately compare tire print evidence, the track left by the suspect tire should be recorded under the pressure of the vehicle. SIRCHTRAK is a new, easy-to-use “drive over” system that gives a permanent record of the tire under load, making comparisons to casts and/or photographs more reliable and eliminating dusting or inking of tires to be examined. Simply lay a sheet of SIRCHTRAK on the impression board and drive the vehicle over it. The pressure of the tire under load causes the interleaved carbon carrier to transfer to the adhesive-coated receiver sheet. Simply peel off the carbon carrier and discard. BENEFITS: Unlike conventional methods of making test tracks, the tire tread imprints are exact, uniform, high-contrast reproductions which become an accurate “signature” of the suspect tire. The SIRCHTRAK printout is perfect for comparison purposes and ultimate courtroom presentations."
