List Of Techniques You Can Use

Here are some techniques that can be used to collect measurable evidence:

• Laser grid (if anything moves in front of the grid created by the scattered beam of a laser pen, you will see a shift or discrepancy)
• Thermometer (an infrared thermometer can be used to measure the temperature of surfaces, it will not measure air temperature)
• Trigger objects (a ball, a bunch of keys, a child's toy, a marble, or any other object left stationary for a spirit to interact with)
• Camera (photographic evidence is the ultimate aim of most ghost hunts)
