"Lorgnette" non-linear junction detector

Non-linear junction detector Lorgnette is designed to detect various kinds of electronic devices containing semiconductor elements, such as eavesdropping devices, microphone amplifiers, audio-recording devices, remote control devices etc., both in switched-on and switched-off modes.

Distinctive features:
- light weight (less than 1 kg);
- the unique antenna (only 18 mm thick) allows the hard-to-reach places to be investigated;
- minimum output power (1 W in continuous mode and 15 W in pulse mode);
- automatic frequency selection allows operation in complex electromagnetic environment;
- possibility to choose either continuous or pulse radiation mode;
- wireless headphones for audio information.
