Dictaphone Jammer Bughunter

The device is designed to protect conversations areas from eavesdropping. Device blocks wireless microphones, tape recorders, hard-wired microphones and most of professional digital tape recorders including tape recorders installed in mobile phones (smartphones). Ultrasonic inaudible noise signal  as well as acoustic speech-like noise signal are used in jamming the eavesdropping devices.

Operation:
The device should be placed so that the transducers be directed towards possible location of eavesdropping devices (tape recorders, microphone, "bugs" etc.), for example, toward the new visitors or clients. The optimal distance from the transducers to microphone of the eavesdropping device is up to 2 meters. Then switch ON the device and adjust the volume of the acoustic speech-like signal so that you can still hear the person you are talking to. You should hold conversation in a low voice but so that you hear well each other without repeating every word. Use TURBO mode for more effective jamming of the microphones.
Do not switch on the acoustic speech-like signal when you want the device to be hidden. Note that this is somewhat reduces the effectiveness of the device (the manufacturer cannot ensure  that if you use only one ultrasonic signal the device will jam all tape recorders).
It is recommended to connect the device to external speakers (e.g. computer) through the special jack in order to more effectively expose the acoustic speech-like signal in a large room. This will protect the large conversation area from eavesdropping as well as to prevent from eavesdropping by external directed microphones (such as laser).
Ultrasonic exposure+voice imitation 100% jaming.
5 ultrasonic tranducers and powerful speaker.
Absolutely soundless operation possible.
Jamming range up to max - 7 m, super effective - 2 m.
Very powerful emission - up to 120 dB.
Able to plug external speakers for big rooms.
Detailed english manual included.
