By means of this searching device, bugging devices which are active in the room, computer or telephone can be located. Thus it is possible to find hidden bugging devices (bugs, mini spys). The device responds to bugging devices with transmitting frequencies of ca. 100 KHz - 2.4 GHz with transmitter powers usual for bugs. Display: 1 x LED for the turn-on control, 1 LED for indication of receipt from one transmitter (the closer you get to the transmitter, the faster this LED flashes). A 9 VDC compound battery is necessary for operation.
