The REM pod- REM stands for Radiating Electro Magnetism.The device works in a similar fashion to the EMF meter by detecting changes in the electro magnetic field. The difference between the two though, is that an EMF meter detects changes levels in background or natural magnetic field where as a REM pod- detects changes in the magnetic field it is generating. The idea is the
ghosts or spirits passing through this field will have an effect and trigger an alarm within the unit.
A word of caution, as it will be easily triggered by any modern electronic item passing nearby.
The REM pod- also includes an ambient temperature deviation detector or ATDD. This detects changes in temperature, again an alleged side effect of ghost or spirit activity.
