Tracking Beacon Set

A set of small, adhesive beacons, easily pressed onto the underside of a vehicle or slipped into a bag, transmitting a steady location signal back to a handheld receiver so the user can follow a target from a safe distance without maintaining direct visual contact.

Each beacon runs on a limited battery and transmits over a finite range, and a routine sweep or a signal detector can locate and remove one if the target thinks to look.
