Hold the phone steady. Watch the meter. Listen. Ghost Detector turns your phone into a paranormal investigator's pocket toolkit. The EMF scanner reads the magnetometer field around you and pulses when something shifts. The spirit box cycles voices the room should not have made. The EVP recorder captures what you cannot hear on your own. WHAT THE METER SHOWS The needle answers the room. Calm fields stay green. Spikes climb yellow into red. Some spikes have explanations. Some do not. You will learn which is which. SPIRIT BOX Three hundred and twenty three voice clips cycle through the audio. Some sound like words. Some sound like answers to questions you just asked out loud. The pattern is the point. EVP RECORDER Press record. Ask. Stop. Listen back. The recordings hold things you did not hear in the room. INVESTIGATION FIELD KIT Built for the kind of night where the house is quiet and you want to know why. Built for friends sharing the phone around a circle. Built for the curious. For entertainment purposes. Ghost Detector is a paranormal investigation toy that takes itself seriously. The readings are theatre. Take them as seriously as you want to. Open the kit tonight.
