Let’s think out of the box for a moment, has anyone ever used a ghost detector? How about foolproof evidence of the existence of ghost? There has never been a piece of equipment made that could prove that ghost are real. As a group HPR uses a scientific approach to paranormal investigating, however the equipment we, and most other groups use, were never designed to find a ghost. I believe that groups need to focus on and use what this equipment was designed for, taking baseline readings, under scientific control, to obtain verifiable data of the environment you are in. The more data collected and recorded the better. Maybe someday enough factual evidence can be recorded to explain how and why our environment (emf, temps, humidity, barometric pressure, moon phases and such) can affect how people perceive what they believe to be paranormal activity.
