Spirit Voice Receiver Transducer Microphone
Simply plug this device into your Voice Recorder and begin an EVP session.
External voices cannot be picked up but spirit voices can.
This is because spirits communicate telepathically and electro-magnetic impulses may be the conduit.
Either way, this simply magnet and copper coil assembly will help to eliminate outside voice contamination during EVP sessions.
Be sure to stay away from high EMF readings while using this device to avoid the hum of 60 cycle electrical interference.
