Electronic detection system of non-linear junctions at the distance of up to 17 m - Lornet 0836

Lornet-0836 is a must-have tool for quick and effective detection of devices with semiconductor components aimed at detecting and annihilating all kinds of surveillance equipment or hazardous devices.

Lornet-0839 is a professional electronic detection system, which encompasses DPF technology (double probing frequency) which allows to detect all kinds of hidden wiretaps, video cameras and other types of electronic devices within 15-17 m, this additionally enhances the safety of detecting any transmitters used for production or detonation of bombs.

DPF provides a great advantage of detecting non-linear junctions as it is better to detect single minor devices through emission of high frequencies, and use low frequencies for detecting in wet soil, concrete walls and etc. With the simultaneous analysis of the second and the third harmonics and due to the characteristics of signal response, it is possible to verify whether you are dealing with an electronic device or natural non-linear junctions (present e.g. in rust).

Device operation is very simple in use and, thanks to its low weight, very convenient. Parabolic large-gain antenna (20dB at 3600 MHz) enables very precise detection of semiconductor components at a large distance, and the laser pointer allows for a more exact search. In the handle there are buttons for quick switch of functions, and just above them there is a graphic indicator with LED diodes which indicates the strength of the detected frequencies.
