Главная ST 400 "CAYMAN"


ST 400 "CAYMAN" nonlinear junction detector  is designed for search and detection of hidden electronic devices installed in walls, floors, ceilings, fixtures, furniture, or containers, regardless of whether the electronic target is radiating, hard wired, or even turned off.
All modern electronic devices contain semi-conducting components. Using a non-linear junction detector it is possible to find these components.


  • Searching for active and passive electronic eavesdropping devices;
  • Detection of mobile phones and SIM-cards;
  • Checking parcels and mail for contraband or dangerous attachments containing semiconductors;
  • Searching for other unauthorized electronic devices comprising semiconductor elements.


Distinctive features:

  • High detection sensitivity at a low output power;
  • Effective work against interference (reinforced structures, corrosion, etc.).
  • Low probability of false alarms.
  • Additional opportunities to identify the response provided by the analysis of signals in the "AUDIO" mode.
  • Ergonomic design, large telescopic bar and retractable armrest provide maximum comfort for the user.
  • Standard replaceable batteries provides up to 4 hours of continuous operation. ST 400 "CAYMAN" comes with two sets of batteries that can increase the uptime up to 8 hours.
  • Optimum balance between price and capabilities.
  • The detector is supplied in a shock-proof case.
