(NLJD)

The device radiates a clean high-frequency RF probing signal into the target area; when this signal encounters a non-linear junction (such as a P-N junction in a diode/transistor) it generates detectable harmonics

It detects electronic components whether they are active, in standby, or completely powered‐off — making it far more effective than standard RF scanners that only detect emissions.

It is capable of penetrating materials such as walls, ceilings, floors, furniture, and containers — enabling the detection of concealed devices embedded behind or within those structures.

User‐friendly in design: features may include telescopic antenna poles for extended reach (e.g., ceilings), LED displays for harmonic response, audio & visual alerts, and adjustable power settings to suit different scan depths.
