TECHNICAL INFORMATION
Laser Trajectory Finder Kit
Catalog No. LTF100
INTRODUCTION
Laser projection is the newest and most accurate method
used to determine projectile trajectories at crime scenes.
The laser is attached to a penetration rod, which is then
inserted into a bullet hole so that the laser beam can help
to determine the direction and angle from the source. It
may also be used to locate bullet exit points and other pos-
sible impact locations. The laser may be used with penetra-
tion rods and centering cones inserted into bullet holes, or
it may be used with the tripod mount to project its beam
through bullet holes.
The No. LTF100 Laser Trajectory Finder Kit includes a
high quality Laser Pointer, Centering Cones, Laser Con-
nectors, Universal Tripod Mount, Bullet Tips, Ballistic
100 HUNTER PLACE, YOUNGSVILLE, NC 27596 USA
