Laser Thermography (Laser Temperature Gun, IR Guns) -

Hot or Cold Spots can be evidence of paranormal activity,
although these are not guaranteed. One of the main drawbacks of
Laser thermographs is a drop (cold) or rise (hot) in
temperature could be related to the normal atmospheric
conditions found in the environment. I.E wood retains heat,
while metal loses temperature rather quickly. So you must be
careful when using this equipment as you could be merely
capturing the heat temperature of the object.

Advanced Use: Find the relative temperature of the room and
it's objects before acclimating the incident to paranormal
activity. Generally unless the investigative area is unusually
cold (such as winter time), the general temperature of
paranormal activity should be registered about at least 30
degrees Fahrenheit above or below room temperature.
