The Estes Method is a paranormal investigation technique that has gained popularity in recent years. It was first developed by Karl Pfeiffer during his investigation of the Stanley Hotel, at Estes Park, in Colorado – the same hotel that inspired horror author Stephen King to write his classic novel, The Shining. The technique involves using sensory deprivation and a spirit box to communicate with potential spirits in a given location. The Estes Method is also known as the SB7 Spirit Box Experiment. The spirit box is a device that rapidly scans through radio frequencies, and it is believed that spirits can manipulate the white noise to communicate. While some see the Estes Method as a bit of a controversial technique as it uses a spirit box (which can be affected by external factors), its popularity and effectiveness in gathering potential evidence is steadily increasing.
