K2 EMF MeterElectromagnetic fields, or EMFs, are emitted by electrical devices of all types. EMFs are everywhere, originating from appliances, cell phones, electrical wiring, and even the human body. The K-II EMF Meter helps measure these fields to identify appliances that produce high-level emissions, allowing users to make informed decisions about limiting exposure. EMF fluctuations have also been associated with locations where unexplained phenomena have been reported, including alleged hauntings. The K-II operates on a single 9V battery, and reports EMF measurements in five milliGauss ranges. The P-SB7 is a miniature sized Spirit Box the size of a thicker iPhone 5. The P-SB7 has been widely used in various paranormal TV Shows with remarkable results. When used by a properly trained individual, under certain circumstances, the P-SB7 will provide results similar to that of an EVP recorder, but in real time. The P-SB7 utilizes a milli-second adjustable Forward or Reverse frequency "sweep" technique coupled with a proprietary high frequency synthetic noise or "white noise" distributed between frequency steps. This modeloffers an enhanced FM frequency sweep which includes an additional 119 new frequencies from the earlier versions 76MHz to 87.9MHz. No other Hack Box or Modified radio currently offers this. A seven step adjustable sweep rate provides user flexibility based on individual technique and session circumstances. There are two discreet audio outputs; (1) 15mW Earphone, and (1) 250mW Speaker. A bright EL back light display with manual ON/OFF select is ideal for viewing in the dark. The P-SB7 uses three "AAA" batteries. The P-SB7 is intended to be used by professional investigators to help promote the field of Paranormal ITC Research. This model sweeps only the FM band, which is preferred to avoid AM talk radio to be confused with a ghost voice.
