Sorry, I guess I'm just too "old school." EMF meters seem to pick up more pollution from electrical systems, etc during investigations than genuine valid data. Way back when, my Dad used dowsing rods which seemed to ignore electrical pollution and home in on the phenomena he was seeking instead. Granted, more often than not, there was little or no activity happening, but when the rods got active, you knew you were in for a good time! I too, have chosen dowsing rods over the EMF meter as a way of paying homage to Dad's memory, as well as showing respect for the very souls who choose to communicate with us.
Imagine being a spirit from the 16th century being bombarded with frightening and unknown equipment. True communication occurs only when we show genuine respect for the spirits we encounter. Dowsing rods were used during their time on Earth and as a result pose no threat-logically, would it not make more sense to make those we seek to engage as comfortable as possible?

For years between "ghost hunter" EMF meters have become the main tool. Here they are and some of its qualities.

What is an EMF?


EMF stands for English for "Electromagnetic Field" in Castilian it be "electromagnetic fields". With electric fields exist where there is a difference of electric potential and magnetic fields exist where there are electric currents. And Faraday's law all electrical current generates an electromagnetic field and vice versa.


Whoever wants to know more about it please visit:



There are electromagnetic fields in a thunderstorm, on a computer, a cell in our bodies, we are surrounded by electromagnetic fields differing in frequency, intensity, and so on.

Why measure EMF?



Among the paranormal researchers think that the presence of spiritual entities produce alterations and / or spikes in electromagnetic fields (EMF) hence the importance given to the electromagnetic field measuring devices.

EMF Meters



EMF Meter is the common name given to what would be more correctly magnetometers meters or magnetic flux density, but no further complicating the terminology. These meters consist of a sensor EMF ("common" or triaxial) and give a reading on a scale usually are lights, needles or digital displays. The paranormal research designed to include a visual and audible alarm which reacts to peaks.

The problems



One of the main problems of EMF detectors are sensors. Common sensors are designed to react to frequencies near 50 or 60 Hz, ie frequencies from power lines. This not only makes them more vulnerable to pollution from power cables but will remove sensitivity at other frequencies producing erroneous readings.

This easy: they can show that there is a low-intensity magnetic field when high intensity is indeed "wrong" because the instrument is very sensitive at that frequency. For example, consider the sensitivity of CellSensor (TM) created by Trent Brandon, a classic team of paranormal research.



As we can see the "strong" sensor is between 50 and 1000 Hz which is a rather poor spectrum.

Triaxial Sensors



The cheapest equipment is very directional sensors that take the direction of the EMF in a single "meaning" say, when in fact the field is three dimensional. To solve this in a somewhat more sophisticated equipment used sensors called Triaxial sensors is measured in 3 directions by providing a better reading.

"SUM" function



Meters on the market as the "Natural EMF Meter Trifield" that have a more than interesting. The team has named the "SUM". This will indicate when the electromagnetic flux changes from the background reading. Are these changes just as important when it comes to "ghost hunting"
