Digital Barometer
THEORY:Â In theory when a spirit/ghost starts to manifest it may cause an increase/decrease in barometric pressure.
NOTE:Â Besides barometric pressure this device also has an altimeter, compass and an ambient thermometer.Â
HOW TO USE:Â Â Â Â Â Â - Â Take base readings so you can compare the readings youÂ
                                            take out in the field, to see if there is any activity.Â
Look for an increase/decrease in pressure during the                                           investigation.
When the investigation is complete, log your readings in the logbook.
RANGE: The range of readings on this meter is from 350hPa to 1100hPa. Â
READINGS: The unit of measurement for pressure is hectopascal (hPa). If there is an increase/decrease of 20hPa, then it could be considered paranormal activity. If pressure starts to decrease from 1000hPa to 980hPa, this means that there is a severe storm coming your way, or is present. If pressure decreases to 950hPa or below, then that means there is a hurricane present. NOTE: If you have an Ion Counter present during the investigation when there is a decrease in pressure, due to a storm, then the Air Ion Counter should read positive ions in the air. If the pressure starts to increase during an investigation to 1000hPa or above, then this could mean that the low-pressure storm system is moving away from you. NOTE: The readings listed for weather are based on coastal regions, not inland.
