Which one of the following is not a component of bomb detection and disposal equipment ?

Bomb Detection and Disposal (BDD) equipment consists of specialized tools used by bomb squads to identify and neutralize explosive threats. Bomb blankets are made of high-strength ballistic fibers used to cover a suspicious object to contain fragments and blast pressure. An electronic stethoscope is a highly sensitive acoustic tool used to detect mechanical timers or clockwork mechanisms inside a bomb. A bomb disposal suit is heavy body armor designed to protect the technician from blast overpressure, fragmentation, and heat. In contrast, a handheld weapon (such as a pistol or rifle) is standard combat or self-defense gear for security personnel but is not a functional component of the technical bomb disposal process. Other common BDD tools include X-ray scanners, Non-Linear Junction Detectors (NLJD), and Remotely Operated Vehicles (ROVs).
