Designed for the rigor of the bureau, this kit is primarily for measuring footwear and tire track impression comparison. Made of rigid plastic and features glare free finish. The l-scale set provides maximum contrast by featuring black markings on a white background on one side and white markings on a black background on the reverse. Alternating black and white bands provide an excellent visual reference from a distance and crosshairs at each end provide a means for checking and correcting perspective distortion.
