Features Strong Durability: This hunting supernatural tester is small and portable, easy to operate, made of high -quality ABS engineering materials, is solid and durable, and can quickly respond to the test results. Five LED Indicator Lights: This magnetic field detector has five levels of detection indicators, which represents different EMF radiation values, and the response to EMF fluctuations and peaks is fast. Excellent Performance: This Magnetic Field Detector is used for super wave wave research and general EMF detection. It uses reliable and excellent effects and super sensitivity, and provides accurate readings. Easy To Use: This magnetic field detector uses colorful LED lights. It is more convenient to observe the reading. It can be noticed during the day or darkness. It is easy to carry and easily place it in pockets or bags. Widely Use: The range of EMF meters used for ghost hunting helps to measure electromagnetic fields to identify devices that generate high radiation, enabling users to make decisions about limiting exposure. Suitable for Home EMF Inspections, Office & Outdoor.Ghost Hunting Equipment for Halloween.
