Ghost Hunting Equipment: K-II Meter
Class of Instruments Known as EMF Detectors

A K-II (K2) meter is a part of a class of instruments known as EMF detectors. When the K-II Meter is exposed to an electric field an electrical current is induced
within the devices circuitry.

The strength of this field and the induced current is then measured from a 5 LED light up scale which indicates the intensity of the field.

K-II meters are usually modified for Ghost Hunting so that they are accurate during paranormal investigations.

A K-II Meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.

The K-II Meter was made popular by it's appearance in the TV show 'Ghost Hunters'. Starting around the third season, the Ghost Hunters team have used the K-2 (or K-II) meter, a type of EMF meter that uses a series of LEDs to measure the strength of an energy field instead of a numerical LCD screen.

During the Manson murders investigation in particular, the team used a K-2 meter in an attempt to get "yes" and "no" responses to verbal questions posed to a supposed entity in a room.

K-II Modification for Paranormal Investigations

This video explains why a K-II EMF meter
must be modified for accurate useful readings during paranormal investigations.

Usually a penny or dime is used to hold down the lever to keep the K-II unit continuously on.

The theory is that spirits produce a magnetic field which they can manipulate which is why a K-II meter may be able to detect the paranormal.

When using a K-II meter for the detection of ghosts the ghost hunter should hold the K-II meter firmly. You do not want to jerk the K-II meter or use fast motions since this type of action can create false results.

Some ghost hunters will hold the K-II meter in their hand, while others will put the K-II meter on a surface. Both methods will work. Just be aware of any possible interference from other devices. Items such as radios, TVs, power lines, etc. can effect the K-II meter and provide negative results.

When using the K-II meter you want to ask controlled questions with a 'YES' or 'NO' response. Most ghost hunters will use the K-II meters responses as flashing twice for meaning 'yes' and one flash for meaning 'no'.

The K-II Meter

This was recorded on 6/22/2008 at Fort Mifflin
during a TAPS sponsored field investigation. It was near casemate11.

Jason and Grant from TAPS conducted this session where it appears they were communicating with an entity from the 18th century using a K2 meter.

Grant provided one meter while other investigators provide two other meters which you can see in the video.

Several questions are asked and the meters appear to react by making its lights flash.

According to Grant Wilson from Ghost Hunters:

"The K2 meter measures magnetic fields, and it's been specially calibrated for paranormal investigations. The theory behind the K2 meter is that if there's a spirit in the area, the K2 meter will pick up it's magnetic field. You can then train the spirits, supposedly, to intensify its magnetic field, therefore lighting up the lights on the meter."

K-II Meter Tips

  • Always make sure you are using new batteries as old batteries will generally affect the performance of a K-II meter.
  • Hold the K-II meter firmly and do not jerk the meter or make fast motions. Set the meter down on a solid surface if possible.
  • Be aware of your surroundings. Other devices such as radios, TVs and power lines can affect the results of the K-II meter in a negative manner.
  • Use controlled questions that will force a yes or no reply. Most ghost hunters will attribute two flashes on the K-II meter for a response of 'yes' and one flash for a response of 'no'.
