Direct experiments reveal how easy that is to handle one of the most popular devices of “search for ghosts” and show that the basic understanding of this device is clearly outside the range of the “scientific” ghost hunters.
A simple handheld device has become a standard tool of paranormal research and cultural phenomenon – the now famous “K2 Meter”. Since its debut in a popular paranormal show, the K-II (K2) EMF Meter has become an indispensable device in the backpack of all ghost hunters. Is difficult to find a team or a series of television that not is using the meter K2, many times as their main source of “detection of ghosts”.
Looking at this device in person, on television, and more than a few hundreds of YouTube videos, some interesting observations can be made. The most obvious is that nobody is using the device as it was designed originally – as a meter of electromagnetic field.
The sole purpose for which many researchers and ghost hunters buy a Detector of electromagnetic field is to help them locate ghosts. In addition, the reason for most of these ghost hunters specifically buy a meter K2 is because they believe that the device allows to communicate with nearby spirits. Obviously, an EMF detector does is none of these, nor was never designed for this purpose.
The purpose of any electromagnetic field meter is to locate sources of electromagnetic radiation (magnetic, electrical and RF / microwave) and provide a reading of the relative strength (and address, if you are an expert and competent operator) EM field.
An overview of the K-II meter
The K-II meter, also known as “Safe Range EMF”, is a simple single-axis electromagnetic field meter. The device is encased in a hard plastic case and is powered by a single 9 volt battery. A sensitive switch to pressure on the front turns on the device, using the thumb to keep pressure (a fast cutting is to slide a coin between the switch and case). There are versions modified available that have added a switch of lever, allowing that the power remains on without the need of keep constantly the button pressed.
Five LED lights are the screen that divides the meter (in milligauss) measurements at five levels; 1 green = less than 1.5 mG, 2 green = 1.5 mG to 2.5 mG, 3 yellow = 2.5 mG to 10 mG, 4 Red = 10 mG to 20 mG, 5 red = more than 20 mG. Once turned on the power, the device performs a self-test: flashing LED lights on, from the first to the last (green to red), and then return to the first green LED. Does it twice, and makes it fast (important to remember later).
The device operates at a level of 50 and 60 Hz. It can detect extremely low frequency (50-1000 Hz) and very low (1,000 to 20,000 Hz) frequency range. I must point out that some retailers of this device to announce that it operates as low as 30 Hz. A common mistake among paranormal enthusiasts is that when they use these devices, they are measuring “the” electromagnetic spectrum – i.e., the entire electromagnetic spectrum. The fact is that they measure only a small portion of the spectrum. The KII covers only the ELF and about 1/8 of the portion of the spectrum–a small fraction of the entire radio waves.
The response time of the K2 is almost instantaneous. As “single-axis” meter, only reads an axis, from left to right (do not read the other two axes). This means that the meter must be turned in the three axes (X, and y Z) to obtain the most accurate reading. My own tests, the device reads better fields directly in front of him – holding device so that the LEDs are against you and a source of EMF is on the opposite side of the device (behind).
Once opened the device and take a look inside, its simplicity is revealed. There is no much – a circuit board and battery. The device is produced by a company called K-II Enterprises, which also produces other three devices. The company also produces other three devices; El Dazer II® (ultrasonic anti-fouling device), the Pet – Agree® (ultrasonic pet trainer) and the Tattle Tale® (a vibration alarm to train pets and safety).
The device weighs 3.8 ounces and measures 5.5 inches long, 2 inches wide and 1 inch deep. To the passing by the web site of the company. I found no mention of its use as a paranormal detection device lo-than-ever. It sells for $59.99 
Meter K2 earned its considerable reputation after appearing in the third season of tv Ghost Hunters ghost hunting program. It was stated that device allowed the communication of spirits through the manipulation of the LED lights on the meter. In an episode that covers an investigation of the Manson murders, Grant Wilson says:
“K2 meter measures magnetic fields, and has been specially calibrated for Paranormal investigators.”
I have yet to find out exactly how this device might be “specially calibrated” to paranormal investigators (but it is on TV, so it must be right… isn’t it?). The statement is not only false, it is absurd.
The alleged communication with the other side is achieved by asking several questions, and spirits (or other entity) would respond by making the LEDs flash in one of two ways – in quick succession to the third, fourth, or fifth LED, then so fast down… or all LEDs lit in rapid succession, and then down – twice. Hunters of ghosts who are asking questions to the spirits would comply with a standard code: the lights will blink once for “No”, twice for “Yes”.
Internet contains a lot of web sites and videos that show how the K2 meter, how to modify it, and examples of individuals who show how (believe) that detects spiritual entities. There are so many videos and websites that show how easy that is to manipulate the sensor, thus producing the desired results of ghost enthusiasts everywhere. The most notable of these manipulations is to find the “sweet spot” in the on/off switch – apply the sufficient pressure on the switch so that it seems to be completely depressed, but the switch is doing the slightest touch. This allows the operator to manipulate the device, making the LED dance madly and / or blink twice on a consistent basis (remember the self-test when turned on?).
In the website ‘ The KII EMF Meter’, says: “the meter of EMF K-II is the companion perfect that like bring in all your research paranormal to ensure the greater possibility of capture the activity paranormal”. Bold statement, it has never existed, and still there is no scientifically valid evidence to support such claims.
With the popularity of these devices in paranormal-themed programs and Ghost hunting equipment (and even with Bigfoot hunters now), I decided to make some simple experiments to see how it behaves the device against a little critical criticism. Regardless of what the people of TV review of these devices can make (detect / communicate with spirits), no one had tested devices in conditions encountered during a “ghost hunt”. I wanted to see what else, apart from the ghost assumptions, would make these devices will illuminate.
I had invited to participate in a hunt for ghosts public in the Sun Inn, located in Bethlehem, Pennsylvania by a group paranormal local. This was a good opportunity to see a group using the device, as well as to observe how it reacted with other standard equipment used. The first four experiments is performed during this hunt of ghosts. The other six were made in my office.
I used a Gauss Master meter to compare sensitivity of the meter of safe reach (K2). Two meters K2 were used in the first of these experiments, along with a Gauss Master EMF meter. The three meters were placed on the floor, with no more than three feet between them. Once the devices were in place, they were not manipulated at all (without human contact). There was a constant measuring just 2 mG which we use as baseline (verified by the master of Gauss).
