This is a must have item for anyone interested in the paranormal. The P-SB7 has given ample proof that it can instantly transmit unexplained voices. These voices, referred to as EVPs (Electronic Voice Phenomena), typically express intelligence since they often call out things that identifies people present at the investigation or something that pertains to the investigation. Also, communications coming across typically co-relates to the known facts about that haunted site, such as specifics about the spirits there. The P-SB7 is the most famous tool for instant spirit communications since it has been the favorite on numerous Paranormal TV-Shows.
The P-SB7 works by scanning the FM band and AM band along with a unique high frequency synthetic noise, a.k.a. white noise, where spirit voices seemingly are able to form words. The P-SB brand’s FM band scans 320 FM frequencies, which is further than any other competing brand known on the market, from 76 MHz to 108 MHz. Also, unique for the P-SB brand is that the band sweep speed can be selected – and from 7 different millisecond speeds. One can also sweep forward or backwards. Improvements, other than the added FM frequencies, from earlier versions of the P-SB7 are: 1) a Noise Cancellation Circuit has been added to the FM band for clearer transmission 2) the AM band is no longer tuned down, it can now be heard equally well as the FM band. 3) a free external speaker is provided (due to improvements, the internal speaker volume is not strong enough – the external one or earphone must be used). The P-SB7 uses 3 "AAA" batteries (included).
