Hadden Nite-Vision Camcorder.
The E.M.F. Meter: Easily the most popular, and portable of the modern ghosthunters kitbag. The meter detects variable electromagnetic fluctuations in the atmosphere around you, and indicates strong readings via sound. Explore haunted sites with this gadget, and you will soon be locating psychic hotspots,
unexplainable earth forces and natural sources of electrical power. Use the E.M.F. to ‘zoom in’ on actual areas, and locate the source of the disturbance. Be warned, do not use around electrical appliances, as the readings will mislead you.
