JJN Digital EDD-24T Handheld Electronic Device Detector is a Non-Linear Junction Detector (NLJD) that detects all types of electronic equipment, no matter if active, passive, or powered off. 

The EDD-24T detects contemporary electronic devices like mobile phones, tracking devices, listening devices, covert cameras, digital voice recorders, Nano/ SIM cards, etc. It will detect them in all working mode scenarios: powered on, powered off (and without any power), in standby mode, and in use.

 

How does it work? Semiconductors in current electronic products are made using silicone. Silicon responds with a strong second harmonic frequency when high-frequency radio signals are transmitted directly over it. In contrast, bi-metals and oxidized metals respond with a third harmonic signal. The NLJD transmits a focused directional signal on 2.4 GHz (ISMBand Type B) and receives on 4.8GHz (Second Harmonic) and 7.2GHz (Third Harmonic).

This means, that when a high-frequency radio signal hits even the smallest amount of silicone, like the ones found in mobile phone parts, SIM cars, and so on, the high-sensitivity receiver will respond to it (with a strong 2nd Harmonic frequency) and thus detect it. The same goes for the 3rd Harmonic receiver that responds to metals and bi-metals and can serve as a good confirmation source for signals that are at first ambiguous.

EDD-24T NLJD is user-friendly and allows a wide range of people to use it; from beginners to professionals. It uses an intelligent algorithm to analyze the detected signals (2nd and 3rd Harmonic) and evaluates the material probability (Silicone or Metal). It has receivers equally powerful and sensitive when compared to much larger portable units on the market.

It is compact, enclosed in machined Aluminium, and has a battery life of up to 4,5 hours. The Audible Tone and Demodulation Function is available via the speaker or the provided earphones.

It is made in England (designed, manufactured, and tested), while abiding by high technical standards and delivered in a Military Standard carrying case.

EDD-24T NLJD for Active and Passive Devices FAQs

Can the EDD-24T detect devices that are powered off?
Yes, the EDD-24T can detect electronic devices even if they are powered off, in standby mode, or without any power source. This is due to its ability to detect the silicon and metal components of electronic devices through high-frequency radio signals, which do not require the device to be active to be detected. This feature is particularly useful in counter-surveillance and security applications where devices may be hidden and powered off.


How does the EDD-24T NLJD work?
The EDD-24T NLJD works by transmitting a high-frequency radio signal that, when it encounters silicon, such as in electronic devices, responds with a strong second harmonic frequency. Metals and bi-metals respond with a third harmonic signal, allowing the device to differentiate between silicon-based electronics and metal objects. It operates on a 2.4 GHz frequency for transmission and has receivers for both 4.8 GHz (second harmonic) and 7.2 GHz (third harmonic).


How far can the EDD-24T detect devices?
The EDD-24T can detect the newest NANO SIM cards from up to 20cm away, showcasing its sensitivity and range in detecting small and sophisticated electronic devices. This range is indicative of its overall capability to identify various types of electronic equipment from a reasonable distance, making it effective in a variety of security and counter-surveillance scenarios.


Is the EDD-24T NLJD easy to use?
Yes, the EDD-24T NLJD is designed to be user-friendly, with a simple operation interface that is suitable for both beginners and professionals. It features an intelligent algorithm that analyzes detected signals and evaluates the material probability, making it straightforward to identify the type of device detected. The device’s design focuses on ease of use without compromising on the accuracy or sensitivity of detection.


What comes included with the EDD-24T NLJD?
The EDD-24T package includes the Handheld NLJD Electronic Device Detector, a 110V to 240V AC input charger with auto-switching and international adaptors outputting 5V DC 2A, earphones, and a compact Military Standard Carry Case. This comprehensive package ensures that users have everything they need to start using the device effectively right out of the box.


What is the battery life of the EDD-24T NLJD?
The battery life of the EDD-24T NLJD is up to 4.5 hours, allowing for extended use in field operations without the need for frequent recharging. This makes it a reliable tool for comprehensive searches and security checks. The device comes with a charger and has been designed for efficiency and longevity in operational use.


What is the JJN Digital EDD-24T NLJD?
