Feature: 1. Anti‑eavesdropping detectors use the principle of radio detection to detect closet eavesdropping devices. 2. With 1MHZ‑8000MHZ high frequency range, has wide application range, strong practicability. 3. The shell is made of ABS material, which is light and wear‑resistant, and is not easy to corrode after long‑term use. 4. One‑piece design, which has glossy appearance without burrs, more stable installation and use. 5. With probe and antenna, the signal response is very sensitive, you can quickly find the source of the bug.
