Open the door to the paranormal with GHOST SCIENCE M3™, the pinnacle of ghost hunting technology. Trusted by the world’s leading professional investigators, GHOST SCIENCE M3™ is the culmination of over a decade of research and innovation. GHOST SCIENCE M3™ stands as the most advanced, comprehensive, and powerful paranormal investigation toolkit ever created. Nothing Compares. Vision The Vision instrument employs structured-light lidar-enabled infrared laser grid imaging, AI-driven computer vision, GPU-based image filtering, and advanced hardware management to deliver unparalleled night-vision, image processing, and real-time human-like figure detection. *Lidar is available only on Pro devices. Spirit Box The Spirit Box instrument leverages live streaming radio stations, advanced signal processing, real-time audio analysis, and dynamic frequency scanning to generate a blend of white noise and brief audio fragments. It is hypothesized that spiritual entities can manipulate these audio fragments using their energy, resulting in intelligible communications. Spatial Matrix The Spatial Matrix instrument uses LiDAR depth mapping, real-time mesh reconstruction, and GPU-accelerated analysis to visualize the geometric structure of the surrounding environment. It is theorized that paranormal energies may subtly distort these patterns, allowing investigators to observe potential manifestations within three-dimensional space. *Pro devices only. Music Box The Music Box instrument employs advanced sensor integration, real-time data analysis, and precise environmental monitoring to detect subtle changes in the ambient environment. In the realm of paranormal research, this instrument is utilized to identify the potential presence of paranormal phenomena. PEVP-VOX The Spirit Vox instrument generates a continuous sound bed composed of phonetic fragments, tonal shifts, and raw audio textures through advanced sound synthesis and real-time modulation. It is hypothesized that subtle environmental influences can manipulate these fragments, shaping them into speech-like bursts that may convey meaningful communication. EVP-ITC The EVP-ITC instrument employs full sensor integration to detect subtle environmental fluctuations and presents words based on an advanced, proprietary phonetically-based computational algorithm. Instrumental Trans-Communication (ITC) devices operate on the theory that paranormal entities can communicate by influencing the ITC device’s sensors. EMF The EMF instrument allows for precise detection, measurement, and visualization of ambient electromagnetic field levels across the electromagnetic spectrum in real-time. It is hypothesized that paranormal entities can influence and generate electromagnetic fields, which are detectable by the EMF instrument. Audio-EVP The Audio instrument analyzes intricate and nuanced audio signals to provide insights into the underlying acoustic properties of the environment. It is theorized that spirits or supernatural entities can manipulate acoustic wave data to produce electronic voice phenomena (EVP) not audible during the initial recording session. Frequency-EVP The Frequency instrument analyzes complex frequency signal harmonics to identify subtle variations and anomalies within the underlying acoustic environment. It is suggested that high audio frequencies, near and beyond the limit of human hearing, could be linked to paranormal phenomena. Geoscope The Geoscope instrument leverages gyroscope and accelerometer sensors to detect even the minutest device movements or vibrations. This functionality is predicated on the hypothesis that paranormal entities can induce subtle vibrations, such as footsteps or knocking sounds. Barometer The Barometer instrument employs the device’s advanced barometric sensor to detect extremely subtle variations in ambient pressure. This functionality is based on the hypothesis that paranormal phenomena may induce sudden or unexplained changes in pressure.
