P-SB7
The P-SB7 is an AM/FM Radio device that sweeps radio frequencies at a fast sweep rate. It is called a "Spirit Box". It is said that entities can manipulate radio frequencies to speak or possibly that the white noise generated by the device allows them to speak through it. The device has many features. It can sweep forwards and backwards non-stop for detection. Gary Galka of Pro-measure developed this device. We never use any audio from this device as proof of the paranormal, but it is fun to play around with.
We have also purchased a Faraday Cage to help reduce Radio Frequency waves while using the device.
