If ghostbusting is your thing, you’ll want to check out this K2 EMF meter before you get slimed. EMF (electromagnetic field) energy is similar to what is emitted by your gadgets. The device is simple and portable and will have you catching ghosts so easily that you’ll hear them cursing you out when you review your audio recorder for EVP(Electronic voice phenomenon).
The device has 5 LEDs for different levels of EMF. It even knows the difference between EMF emitted by you and your gadgets and by paranormal spookery. EMF from gadgets will light up the LEDs and remain steady. Paranormal activity makes the meter spike since spooks emit a pulsating EMF energy. An otherworldly specter will cause all 5 LEDs to light up and flash. I can attest to this, since I have one and it did the exact same thing when my mother-in-law came over.
