Non-Linear Junction Detector with 140cm Pole for Hidden Devices

Find hidden electronics before they find you. This detector reveals surveillance devices even when they are turned off, giving you clear awareness during professional sweeps.

Scan rooms, furniture, walls, and hard-to-reach areas with confidence and spot concealed electronics based on the materials inside them—not their power state.

Detect hidden electronics with total control and clarity

✅ Locate devices even when powered off, revealing what standard scans miss

✅ Detect tiny components like Nano SIM cards from up to 20 cm away

✅ Reach ceilings and confined spaces with an adjustable pole up to 140 cm

✅ Instantly identify signals as silicon or metal for faster decisions

✅ Perform sweeps without looking down using real-time audio tone feedback

✅ Stay operational for up to 4.5 hours on a single charge

This non-linear junction detector works by scanning for semiconductor materials found in all modern electronics. It transmits a 2.4 GHz signal and listens for harmonic responses, allowing it to detect devices regardless of whether they are active, idle, or completely powered down.

The 3.5-inch daylight-readable display shows signal strength clearly while categorizing detections as silicon or metal. This makes it easier to distinguish real electronic threats from common materials during inspections.

The adjustable extension pole extends from 30 cm to 140 cm, helping you check ceilings, vents, and elevated surfaces without strain. A five-position adjustable head ensures you can keep the screen visible while scanning, and included counterweights improve balance during longer use.

Audio feedback adds another layer of control. The tone changes with signal strength, so you can sweep efficiently without constantly watching the screen. A demodulation mode lets you listen to detected signals for deeper analysis.

Unlike basic detection tools, this unit identifies actual electronic components rather than relying on power signals. Combined with its lightweight design under 1 kg and durable aluminum casing, it is built for real inspection work in varied environments.
