Tracer kits tag a target with a small electronic bug to allow finding and tracing the target. The kit consists of a small pen size launcher and a dozen tracer bugs. The pen can launch a bug up to two meters or simply attach the bug by touch to a person, item of equipment, robot, or vehicle. Each bug is coated with an adhesive and small enough to escape notice. The bug transmits its location using either local communications networks or an internal radio with a 5km range. The internal battery last for a few hours, longer at higher TLs. If tracked over time the data can be fed into a Map Box or Hand Computer to produce a map of the locations of the tracer, including velocity, altitude, and other positional information.
