Electromagnetic field detectors are very useful tools provided they are used properly.  There are instructions with each type that you should read.  These meters detect fluctuations in EM fields.  These ranges vary for 3 feet to 30 feet.  Many things will give readings on an EMF meter but what we are looking for is abnormal and unnatural readings that have been tied to spirit activity.  Each of the EMF meters pictured are the ones that I use.  Each one has it's own benefits.  (From left to right) The Electrosensor EMF has a range of 3ft and a light up led display.  It can give you readings within 1 milligauss.  It runs about $29.00.  The ELF Zone one has 3 lights, the middle of which is almost exactly the range we are looking for during an investigation.  It's range is 10-12 feet,.  These cost about $12.00.  The Trifield Natural EM meter is one of the best.  It is very sensitive to movement and vibration so be aware of that.  One the plus side it has an audible alarm to let you know that your meter is getting a reading.  It's range is approximately 25 feet and it runs about $250.00.  The KII EMF meter is a great handheld meter with an easy to read led light readout readout.  It's range is approximately 12-15 feet and it runs about $60.00.    The final one to the far right is the Cell Sensor EMF meter.  The cell sensor is my meter of choice.   I can be used in a stationary position or walk around with it. It has both audible and LED alarms to let you know when you have a reading.

EMF Detector -  The Electromagnetic Field Detector, also known as an EMF, is the modern day ghost researcher's tracking device, a very important piece of equipment.  With this instrument it is possible to locate and track energy sources.   It will detect fluctuations in electromagnetic fields and low strength moving EMF fields that have no source.  It is a common theory that spirits disrupt this field in such a way that you can tell one is present by higher than normal readings with this meter.  Before using the EMF as a ghost research tool on an investigation be sure to walk around the area and take initial readings around energy sources such as light poles or electrical outlets to be sure of the readings you receive while scanning the area during the investigation.  Most units when purchased come with a manual describing most household and major appliances and their corresponding electromagnetic reading.   When using the EMF as a tracking device look for fluctuations of 2.0 to 7.0, this usually indicates spirit presence.  Anything higher or lower is normally has a natural source. 

SJGH training sheet I give all my new trainees on EMF meters. 

This new meter is made by the same people who make the Cell Sensor.   Unlike the Cell Sensor, it is an EMF meter only and does not have a separate probe.   It's other features are:

50 & 60 Hz operation 
Flashing red light and audible alarm when it gets a reading 

1 - 5  milliGauss ranges
