Crewell Electromagnetic Field Detector - with 9V Batteries - Ghost Hunting - Paranormal Activity Equipment

1. The electromagnetic field detector for ghost hunting helps measure electromagnetic fields to identify devices producing high-level emissions – allowing users to make informed decisions about exposure limits. 2. The detectors have been associated with locations where unexplained phenomena such as ghosts have been reported. The ghost hunting detector operates on a single battery and reports electromagnetic field measurements in the range of five milligauss. 3. Measures a wide spectrum of electromagnetic fields between 50 Hz and 20,000 Hz – it can register a cell phone within a range of 60 cm. 4. Measure the electromagnetic level to protect yourself from overexposure to electromagnetic fields, which can be harmful in the long term. 5. Convenient to use - One-button operation to turn it on and off - Portable - Robust - Reliable - Highly responsive with an easy-to-read LED scale in the dark and in sunlight. Note: All data is measured manually; please allow for a 1-3cm error.
