Winkelmann has developed a portable, field operatable handheld NLJD system, which is an advanced detector using the Harmonic Radar principle to aid the security professionals in the search of concealed electronic devices.

The HAWK 450XD provides real time detection against electronic devices containing semi-conductors and bi-metallic junctions. Devices like Radio Transmitters, Power Amplified Microphones and Electronic Timers etc. contain non-linear junctions and will be detected even if they are embedded in the Cabinets and either in conducting or non-conducting states.

Due to global environment of international terrorism, there has been a well-identified requirement for security and specific detection equipment. In the recent past, land mines and explosives are detonated with the help of remote control and electronic timers. The HAWK 450XD is successfully deployed by EOD teams (bomb technicians) to aid detection of improvised explosive devices (IEDs).

The HAWK 450XD is the preferred model of choice of TSCM operators where concealed or buried electronic devices (bugging equipment) must be detected and located. Examples of devices detected are attachments to telephone or mains cables, transmitters of all types, tape recorders, hidden cameras, wired electric microphone systems.
