Designed by Rob Caunt of the Firearms Section of the Vancouver, British Columbia Police Department, the Dual Trajectory Laser Holder is used to hold two trajectory lasers in opposing directions with a high level of accuracy for gunshot trajectory reconstruction. This design exploits the co-axial properties of the laser in its round housing. The mount can also hold a single laser and the Evi-Paq ® Angle Finder. The Dual Laser Holder easily mounts on a standard tripod.
