During an investigation, our researchers utilize various types of equipment and strict guidelines to gather and analyze potential evidence of unexplained activity. Evidence is systematically, carefully, and deliberately examined by our members following completion of the on-site investigation. Frequently, a majority of the evidence can be attributed to natural causes/circumstances. Only a very small proportion of data from any given investigation might be labeled credible evidence of the existence of ghosts. Most investigations yield no evidence of paranormal phenomena following our analysis.

Types of Evidence
EVP
One of the most common forms of evidence collected during investigations are EVPs (Electronic Voice Phenomena.) While adhering to strict protocols, audio recordings are made while one member asks questions that might elicit a response. During review of these recordings, possible responses are sometimes heard, suggesting further analysis. Researchers utilize both analog and digital voice recorders.
