Lornet Star 24S is a nonlinear junction detector (NJD) built for professional counter-surveillance. It uses dual-harmonic analysis of second and third harmonics, selectable pulse and continuous-wave operation, automatic channel search in 200 kHz, 2 MHz, or 13 MHz steps, and anti-jamming filtering. A handheld design with a removable 54–86 cm telescopic rod, modular antenna, and Li-ion battery system supports mobile sweeps in offices, facilities, and vehicles.
Key Features & Benefits
-
Dual-harmonic detection: Confirms semiconductor junctions by reading second and third harmonics, including devices that are powered down.
-
Pulse and CW modes: Use pulse for wide, long-range scans, then switch to CW for precise localization with audio feedback.
-
Smart frequency control: Automatic channel search with anti-jamming filtering maintains a clean working window in busy RF areas.
-
Handheld with reach: Removable telescopic rod extends 54–86 cm to check wall cavities, ceilings, and under-desk spaces.
-
Visual and audio cues: Integrated spectrum display and headphone monitoring provide clear confirmation during a sweep.
-
Modular antenna bands: Hot-swap 800 MHz, 2400 MHz, or 3600 MHz modules to match the environment without changing tools.
-
Manual power and sensitivity: Adjust output power and select receive sensitivity levels directly on the handle for quick control.
Where It’s Used
Deploy for privacy checks in boardrooms, executive suites, laboratories, server rooms, vehicles, and other sensitive areas where passive or active implants may be concealed in fixtures, furniture, or equipment. Mode switching and harmonic readout support both broad scans and pinpoint checks.

Frequently Asked Questions (FAQ)
What is the difference between pulse and CW modes?
Pulse mode provides high-power bursts for faster, wider scans. CW offers a steady carrier and is used to pinpoint a suspect spot with audio and visual feedback.
How does automatic channel search help in busy environments?
It scans available channels and locks a quiet one, while anti-jamming filtering suppresses center-frequency noise to keep readings stable.
How long can I operate on battery power?
Typical runtime is at least 3 hours in pulse mode or about 1.5 hours in CW. The fast-charge container supports quick swaps between the two batteries.
Can I check hard-to-reach areas?
Yes. The telescopic rod extends from 54 to 86 cm to reach ceilings, wall cavities, and under furniture without awkward positioning.
Will it detect devices that are switched off?
Yes. Dual-harmonic detection reads the second and third harmonics from semiconductor junctions, which remain present even when a device is powered down.
