Feature: 1. EMF Meter Range for ghost hunting helps measure the electromagnetic fields to identify appliances that produce high emissions, enabling users to make informed decisions about limiting exposure. 2. The detectors have been associated with places where unexplained phenomena have been reported as alleged hauntings. The K2 Ghost Hunting Detector operates on a single battery and reports EMF measurements in five milliGauss intervals. 3. Measure wide range of electromagnetic fields from 50 Hz up to 20,000 Hz, and it can register a mobile phone that is within 2 feet. 4. Measure the EMF level protect from potentially harmful long-term overexposure to EMF. 5. Convenient push-on/push-off operation; Portable, easy to use, robust, reliable, super responsive with easy to read LED light scale in the dark and sunshine. Specifications: Accuracy: +/- 5%, Detection range: 0 to 20+ milliGauss, Detection frequency: 30 - 20,000 Hz Easy-to-read multi-segment LED display Accuracy of 5% at 50-60 Hz Size: 14.3 x 2.9 x 5.3 cm Batteries: with 1x 9V batteries The five scales: The first light detects a normal EMF field, the one that is always around us. The range is between 0 and 1.5 mg The second light (GREEN) detects a low level EMF, which is between 1.5 and 2.5 mg. The 3rd light (YELLOW) detects an intermediate level EMF in the range between 2.5 and 10 mg. The 4th light (ORANGE) detects a high level EMF field in the range between 10 and 20 mg The 5th light (RED) detects an extremely high EMF range of 20+ mG includes: 1 x EMF Magnetic Field Detector
