Sirchie LTF113 Optional Reflective Yarn, 250' Spool

This reflective 250 ft. (76m) spool of yarn can be used for blood spatter analysis in conjunction with our BSK500 Blood Spatter Kit. By tying it to one of the kit’s wax clips, emphasis can be given to the direction traveled by blood spatter evidence found in the poorest of lighting conditions. It can also be beneficial in ballistics investigations. When integrated with the LTF100 Laser Trajectory Finder Kit, the flight of the bullet and location of its source can be better determined at darkened or poorly lit crime scenes.
