A standard investigation consists of:
EMF Meter- We currently have an ELF Zone EMF Meter, but due to extra room in our Budget, we are looking at aquiring the EMF-822A
A Motion Sensor- A model somewhat in the mid range, it works like a charm picking up Infrared beams off of moving objects.
Infrared Thermometer- A cheap, basic infrared thermometer, great for recording cold spots.
Memorex DVR- Great for recording EVPs
A Journal- Perfect for writing observations in.
Research on the area- What obstacles are located in the area, directions, the story, etc.
