FACT: The digital thermometer detects ambient temperatures in Fahrenheit or Celsius.
THEORY: In theory when a spirit/ghost starts to manifest, it will draw in heat energy around the area, causing either a cold spot or a hot spot. A cold spot would form because the heat energy is being sucked out of the air, causing the air around the entity to be cold. A hot spot would form because the heat energy is being sucked out of the air and confined to a specific area causing a hot spot.
HOW TO USE: The first thing you want to do is make sure the thermometer is set to Fahrenheit. Unravel the cord and probe to give you a more accurate reading. Take a base reading to compare to your other readings later on. During the investigation, walk around and look for any differences in temperature. When the investigation is complete write down your temperature readings in the field report.
RANGE: The range of the cord with the probe is 10 feet. The range from the probe to the active field is 0 to 1 foot.
READINGS: A normal reading is usually a 5-degree difference from your base reading. Typically a paranormal reading has a minimum of a 10-degree increase/decrease from your base reading. If you get a drop in temperature, the drop is called a cold spot. You may also get an increase in temperature, which would then be called a hot spot. Hot spots are rare but they do occur.
