The JJN EDD-24XT is a professional non-linear junction detector (NLJD) for detecting concealed electronic devices, whether they are switched on, in standby mode, or completely switched off. This advanced NLJD was developed in the UK and is used worldwide by government agencies, defense, criminal investigations, and technical security investigations.
Thanks to its telescopic design with an aluminum extension pole and adjustable head, this device is ideal for inspecting walls, ceilings, vehicles, and furniture. The EDD-24XT detects semiconductor components such as those found in microphones, cameras, SIM cards, recorders, smartphones, and listening devices.
Professional detection of hidden electronics
The device operates by emitting an RF signal at 2.4 GHz and measures reflected harmonic frequencies at 4.8 GHz (2nd harmonic) and 7.2 GHz (3rd harmonic). This allows it to distinguish between electronic circuits and non-electronic materials. The integrated software provides real-time indication of whether the detected material is silicon or metal.
Ergonomic design for inspection in hard-to-reach places
The extendable telescopic handle extends from 30 to 140 cm and features an adjustable head that can be locked in five 90° positions. This allows you to perform inspections above ceilings, in baseboards, or under car seats without physical strain. Operation is intuitive, with a clear display and direct audio feedback.
