register any anomalous readings. Starting around the third season, the team has 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. In the fifth season's "Edith Wharton Estate" case, the team introduced two new pieces of equipment: one is a custom-made geophone, which detects vibrations and flashes a series of LEDs that measure the intensity of the vibration; the second is a new EMF detector that makes a buzzing sound when in the presence of an electromagnetic field, and the stronger the field, the louder it buzzes. In the episode, the geophones were recorded on video flashing to the vibrations of what sounded like footsteps across a floor, even though no one was supposedly in the room. Other gear not typically shown on screen are an ion generator, a device that charges the air with electricity and is theorized to help spirits manifest, and the white noise generator, an audio device that makes a static background noise and is theorized to act as a catalyst for assisting entities in making EVPs.
