Non-linear junction detector to search for semiconductors in complex environments: massive ferroconcrete, humid soil, greenery etc.

Non-linear detector


  • 800 MHz signal range
  • Search inside concrete structures and in humid environments
  • Removable telescopic pole
  • Compatible with 2400 and 3600 MHz antenna blocks of LORNET STAR set

Reliable and easy-to-manage non-linear junction detector for searching medium-sized electronic components (radio microphones, voice recorders, etc.), no matter of turned on/off status

Detection capabilities through any obstacles

Convenience of search

The removable telescopic pole, the record-low weight of the device, the small thickness (18mm) of the antenna module allow search work in hard-to-reach places. The presence of an additional battery allows for round-the-clock operation of the device


Detection capabilities through any obstacles

Detection of electronic devices in complex cases, for example when searching in concrete or wet walls, in wet soil or behind vegetation



Any non-linear junction detector of LORNET STAR set can be understaffed with one or two additional antenna modules with a different frequency range, using a common control panel handle and telescopic pole

Transportation packaging

Standart: Originally product kit of LORNET STAR 08 is delivered in a special fabric bag that protects the device from damage

Export: In export version LORNET STAR 08 can be delivered packed in hard plastic case

  • Detection of electronic devices such as bugs, microphones, cameras, voice recorders, telephones, electronic components of explosive devices that may be in the off, sleep or on state
  • Ability to search in wet conditions, for example, wet walls, soil, bushes, etc.
  • A removable telescopic pole allows the operator to easily turn the device from search to inspection mode and vice versa
  • Compact size and light weight provide comfortable working conditions for the operator
  • Maximum search efficiency of any electronic devices in the most difficult conditions when used with other replaceable antenna modules of Lornet-Star set
  • The small thickness (18mm) of the antenna module allows you to conduct search work in hard-to-reach places
  • The presence of an additional battery with a charging time significantly shorter than the discharge time allows, if necessary, to carry out round-the-clock operation
  • The presence of an additional battery with a charging time significantly shorter than the discharge time allows, if necessary, to carry out round-the-clock operation
  • Recognition (identification) of electronic components from natural semiconductors (rust, metal-to-metal contacts, etc.) in CW mode by listening to the signal from the output of the amplitude detector when receiving the 2nd and 3rd harmonics through the built-in speaker or headphones
  • CW mode can be used to identify working analogue radio microphones due to the acoustic feedback
  • Additional assessment of the 2nd and 3rd harmonic levels by ear by the frequency of clicks played through the built-in speaker or headphones
  • Automatically search for the frequency channel with the least interference for working in complex electromagnetic environments
  • Automatic and manual output power adjustment
  • Manual receiver sensitivity adjustment
