ST 400 CAYMAN

Nonlinear Locator ST 400 "CAYMAN" is designed to detect electronic surveillance devices, mobile phones, SIM cards, and other electronic devices containing semiconductor components.
The key distinguishing feature of the CAYMAN series nonlinear locators is their multi-frequency emission mode, which provides several advantages over locators built using conventional designs.

Purpose:
The ST 400 "CAYMAN" nonlinear locator is designed to detect:
  • Covert technical surveillance devices (СТС НПИ)
  • Mobile phones
  • SIM cards
  • Other semiconductor-containing devices
The device can detect both powered and unpowered electronic devices while precisely determining their location. Operators can distinguish genuine semiconductor responses from false signals (caused by corrosion, metal, or MOS-structures).
Key Features:
The "CAYMAN" series' distinctive advantage is its multi-frequency emission mode, providing significant improvements over conventional locators:
  • Enhanced selectivity (improved differentiation of electronic components against metal-oxide-metal structures)
  • Increased detection capability of devices behind partial shielding (e.g., chain-link fencing)
  • Optimized power-to-range ratio
  • Audio-mode identification of detected objects
  • Effective operation in high-interference environments
The proprietary signal processing algorithm reduces false alarms while improving selectivity and response speed.
Package Includes:
Shockproof carrying case.
