An interesting read:
http://www.themortonreport.com…..t-hunters/
I particularly like this portion:
Quickly, though, I discovered just how easy it was to get the [EMF] meter to emit a dramatic squealing sound simply by moving either it or me.
This was unsurprising given what it was designed to detect, but I was surprised – not to say a little concerned – to see at first hand how some researchers were starting to use the same instrument during investigations. They would excitedly wave their EMF meters, and other increasingly hi-tech toys, around with no real understanding of how to use them, while reacting to every inevitable flash and bleep as it were confirmation of a ghostly presence in the vicinity. EMF meters had somehow morphed into ghost detectors.

Question, if someone handed you a black box gadget and told you it was a ghost detector what would you do?
A. Immediately start looking for ghosts with it.
B. Find out how it works and..
C. Find out what else it picks up.
Many ghost hunters I know would go straight for the juggler with option A. A few dabble with option C but don't take sufficient precautions because they have no idea about option B. They "want it now" without taking the time to really understand how things work. And that's why they get an F for fail.

A is the most likely choice probably. Here, download this ghost hunting app for your iPhone. Pretty soon you see posts in places about how it was detecting activity. Really kind of funny and sad at the same time.
Myself, I wouldn't believe in any sort of gadget unless it had a ghost emblem on the side of it

Yeah it's got to be endorsed by J&G too. 
Many would be ghost hunters buy a nice shiny case to put their EMF meter and other gadgets in and leave them in the case until they go for an investigation. That is the only time their meter sees the light of day, oops I mean the dark of night.  The barely wiser ones might take "background readings" for a few minutes of the location beforehand. Blech.
When I bought my EMF meters, the first thing I did was pulled them apart, tried to understand how it worked and then put them on a test bench. Then I would real world test them by taking them with me everywhere. I'd eat with them, sleep with them, carry them on me everywhere I went, drive around with them (this is fun), and leave them running 24x7 for weeks/months/years to really see exactly what activates them in the real world. People think you're up to no good when you carry one of these in daylight by the way. Especially if you point it at them. I'm afraid in doing this it's only made me more skeptical.

I can see Learjet walking down the street with his meter in one hand and poking people with his other like the scene in Ghostbusters with Egon and the man in the hallway opening his hotel room door.

Double tap to the head. Don't become Undead.

You made me watch the movie so I could see that again. Yeah that's me lol.

I'll be totally honest here and admit that when I very first got interested in ghost hunting (2007, I think), I knew very little about any of it.
Just to hammer that point home, the first show I watched was the live special of "Most Haunted" at Eastern State Penitentiary.. and liked it. D'oh.
Little did I know then how bogus that show was.Then, during breaks, they were advertising for a ghost/EMF meter (I forget which term they used) app for your phone, all you had to do was text some number to download and install it. Of course, that only worked on smartphones so I couldn't even attempt it (I didn't have such a phone), but I was unsure at the moment if there was anyway one could actually configure a cell phone's antenna and cpu to detect and display VLF EMF. I'm sure those circuits are hard-tuned to the much, much higher frequency bands of cellular communications and are probably unable to detect anything below a gHz.. if you could even program it to do so.
I would love to take apart my Gaussmaster, Cell sensor, and Trifield EM Natural, except that I have no Oscope – or for that matter, an RF generator. Without that, there's not much I can test, all I have is a DMM and a freq counter.
OTOH, this guy did a good job of dissecting a gaussmaster, so I got a general idea of the basics involved.

You can do a fair few tests using a PC or laptop. There's a number of freeware software Oscope and spectrum analyser programs out there, as well as signal and function generators that use the sound card's input and output.The limits are one side band of the sound card's bandwidth. For instance if you have a 48 kHz soundcard, you can analyse the first 24 kHz. This is plenty for most EMF meters, unless like the K2 they venture into the radio bands. Then I use my amateur radio gear to test them through HF/VHF/UHF.
Using this method I've been able to plot the frequency response of a few EMF meters. This one is for the Gauss Master. http://img268.imageshack.us/im…..master.jpg
This probe which is just a few hundred metres of wire wound around a polystyrene box has a K2 lighting up. http://img203.imageshack.us/im…../hat2b.jpg
I wore this on my head to test the EMF hypersensitivity baloney. http://img815.imageshack.us/im…..9/hat1.jpg
Made a loop for Schumann resonances. But I need more than 1.6km of wire. http://img130.imageshack.us/im…..loop12.jpg
And a few more to experiment with. http://img14.imageshack.us/img…..probes.jpg
All these plug into a Creative USB sound card adaptor for further analysis, VLF listening, plotting etc.
