A spirit box or ghost box is a catch-all term for a device used to verbally communicate with spirits. Many of these gadgets continually scan AM & FM radio frequencies, creating a din of white noise. The idea is the spirit can use that white noise to communicate in some way, either verbally or through EVP sessions.
These are some of our favourite tools to use on The Other Side as they can give the spirits a voice to communicate with our team for a real time conversation. We used the P-SB7 for the first 4 seasons of the show and starting with season 5 started using the P-SB11 which essentially contains 2 P-SB7 units and gives a much broader and more stable spectrum of frequencies and also includes a temperature readout to alert of any ambient fluctuations around the device.
