Locator is capable of discovering the whereabouts of electronic circuitry incorporating transistors and diodes (non-linear junctions) regardless of whether the circuits are powered or not. Radio transmitters, receivers, power amplified microphones, electronic timers, and similar equipment invariably contain semi-conductors and can therefore be detected by Locator. It is simply the most invaluable tool for a technical surveillance counter measure inspection (TSCMI).
The ability to detect a dormant electronic circuit is particularly important in the case of a remotely controlled device or a device in which the battery is awaiting replacement. It also proves invaluable in the detection of 'Trojan Horse' type eavesdropping devices hidden in furnishings or objet d'art.
