"Hear" and Record EMF Energy
The EVP Mic is a ghost hunting device by renowned inventor, Bill Chappell, that allows you to LISTEN to energy. It detects electromatic waves and translates it into audio waves we can hear and record. Just plug it into a recorder and experiment with listening to EMF. 
Listen to EMF Energy.
 
In short, the EVP Mic converts energy into sound. And, honestly, energy sounds pretty cool!
When it comes to paranormal investigating, keep an ear out for when it changes - especially when it shouldn't. What does it sound like? Experiment by walking around the location and 'hearing' what electricity sounds like. Wave the EVP Mic near a computer, a fan or a light switch. Each will have its own electronic signature - or 'voice'.
 
Simple to use with a recorder.
Just plug the EVP Mic into an EVP/audio recorder with a microphone input and hit record. Use headphones to hear it live. Honestly, this device is super simple with no need for batteries. It is powered through the recorder.
 
For ghost hunting, we suggest placing it in one area and listen closely for changes (that maybe shouldn't be there).

A unique way to baseline on ghost hunts.
Baseline readings are super helpful to kick off your paranormal investigation. The EMF Mic provides a more in-depth 'listen' into those readings. Traditionally, this is done with an EMF meter amongst other tools. Instead of that (or in addition to), try using this microphone with a recorder and headphones to tap into the true voice of the location.
 

IMPORTANT: This device MUST be used with an audio recorder, amplifier, speaker or video camera that has a microphone input. We have listed a few above that we have tested to work well.
