TimeWatch TWND-800 Portable Non-Linear Junction Detector (NLJD) The TimeWatch TWND-800 is an advanced handheld NLJD device engineered for the rapid detection of hidden electronics, such as covert transmitters, listening devices, and mobile phones, in secure zones. Utilizing focused microwave signals and harmonic response analysis, TWND-800 identifies non-linear junctions found in semiconductor components, even if devices are powered off or shielded. Key advantages include ultra-sensitive electronics detection (at up to 2 meters distance), rugged shockproof construction, ergonomic handle, intuitive visual/audio feedback, and fast rechargeable batteries for all-day field deployment. Its user-friendly touchscreen, automatic calibration, and spectrum analysis deliver reliable results in challenging environments. TWND-800 is ideal for counter-surveillance, prison inspections, government, military, and VIP protection teams seeking fast and effective bug sweeps.
