1. Product overview:
       ST 031M "PIRANHA" is a handheld wireless anti-eavesdropping detector. The product adopts the latest microelectronic anti-detection technology, which can detect and locate hidden transmitters (bugs), wireless microphones and GSM phone signals in various situations, and provide professional-level radio wave scanning. The product is equipped with a 12-key operating keyboard and a color display screen to display the results. The scanable frequency range is from 0.02KHz to 4.5GHz. It is simple to operate and easy to use. It is a professional and practical product.

2. Features:
ST 031M can operate in a variety of modes, such as:
1) Selective high-frequency electronic signal detection mode (frequency range: 140∽4500MHz)
2) Wired scanning analysis mode (frequency range: 0.05∽30MHz)
3) Low frequency signal amplification analysis mode (frequency range: 0.02∽100KHz)
Special software can:
1) Transfer the information on the ST 031M monitor to the computer screen.
2) During the real-time operation of ST 031M, create image and audio files, or extract data from ST 031M‘s non-volatile memory.
3) When the instrument is working in high frequency detector mode/frequency meter mode/electronic scanning analyzer mode, the scanning receiver can be flexibly switched. The conversion is mainly to adjust the receiving frequency of the scanning receiver to match the received signal frequency.
4) ST 031M is light and easy to carry. When using or storing, use a special carrying case.
