Feature:1. The EMF Meter Range for Ghost Hunting helps measure the electromagnetic fields to identify appliances that produce high-level emissions, allowing users to make informed decisions about limiting exposure.2. The detectors have been associated with locations, where unexplained phenomena have been reported like alleged haunting. The K2 Ghost Hunting Detector operates on a single battery, and reports EMF measurements in five milliGauss ranges.3. Measure wide spectrum of EMFs from 50 Hz up to 20,000 Hz, and it can register a cell phone that is within 2 feet.4. Measure EMF level protect from potentially harmful long term overexposure to EMFs.5. Convenient push-on\/push-off operation; Portable, easy to use, rugged, reliable, super responsive with easy to read LED light scale in dark and sunshine.Specifications:Accuracy: +\/- 5%,Detection Range: 0 to 20+ milliGauss,Detection Frequency: 30 - 20,000 HzEasy-to-read multi-segment LED displayAccuracy of 5% at 50-60 HzSize: 14.3 x 2.9 x 5.3cmThe Five Scales:The 1st Light detects a Normal EMF field, what is always around us.The range is between 0 to 1.5 mGThe 2nd Light (GREEN) detects a Low Level EMF,which range is between 1.5 to 2.5 mG.The 3rd Light (YELLOW) detects a Mid Level EMF in the range between 2.5 to 10 mG.The 4th Light (ORANGE) detects a High Level EMF field in the range between 10 to 20 mGThe 5th Light (RED) detects an Extremely High EMF Range of 20+ mGincludes:1 x EMF Magnetic Field Detector
