ST 401 "CAYMAN", Portable Nonlinear Junction Detector

Non-linear junction detector ST 401 series "CAYMAN" is a portable modification of the basic model ST 400 Thus ST 401 retained all modes implemented in the basic model. The main difference from the basic model, is the lack of a telescopic rod. ST 401 is especially useful when working in a confined space when checking small loads, mail, as well as screening people. ST 401 allows you to detect, turned on and turning off electronic devices, as well as pinpoint their placement. Using the detector, the operator can distinguish between "feedback" from the real semiconductors "false" signals (corrosion, metal structure, metal-oxide - metal).


  • Ergonomic design;
  • Maximum peak radiated output power does not exceed 2W;
  • An original signals algorithm reduces false positives , increase selectivity and reaction rate;
  • The range of the receiver gain is 40dB ( five steps to 8 dB);
  • Having to listen to audio mode demodulated signals;
  • Time of continuous operation from a fully charged battery from 3 to 4 hours;
  • Adjustable tilt antenna module of the instrument;
  • 4 standard battery and charger;
  • Software update via port USB;
  • Locator comes in a shockproof case.
