Energy Meter
Energy meters exist for a wide range of energy sources claimed as useful by occultists. From the etheric energies captured by Kirlian photography to orgone and even psychokinetic energy, an energy meter purports to indicate abnormal amounts of the energy in the background. Most of them are junk: No more than a few circuit boards scavenged from a dead clock radio, wired together and sold on for a vast profit. A few show surprising results. They capture the presence of ghosts, and UFO landing sites cause the meters to spike for weeks afterwards.
- An energy meter monitors a radius up 15 yards (depending on energy interference). If a paranormal energy source enters that space, the meter spikes.
- The meter is a simple yes/no device; a hunter can't get a "closer" or more accurate reading. The precise range is up to the Storyteller, and should vary. Characters in possession of an energy meter shouldn't know the range of their equipment until they have plenty of time and a known supernatural phenomenon to experiment with. Most energy meters spike on the presence of ghosts, mages, and in areas where UFOs are reported to have landed.
- A character using one has the equivalent of the Unseen Sense merit relating to ghosts, Fortean phenomena, and mages, though precisely what sets it off depends on the meter.
