The P-SB7 is a miniature sized Spirit Box the size of a iPhone 5 about – but thicker. The P-SB7 has been widely used in various paranormal TV Shows with remarkable results. Zack on Ghost Adventures was first with using it on TV and ususally just calls it the SB7. On its premiere on TV the The P-SB7 provided responses to Zack’s questions in real time over a 40 minute segment of the show. When used by a properly trained individual, under certain circumstances, the P-SB7 will provide results similar that of an EVP recorder, but in real time.

Since introducing the P-SB7  three years ago, the FM frequency sweep method has clearly become the preferred technique used by Zak on Ghost Adventures and is used by paranormal enthusiasts world wide.

As such, there are two distinct differences that set the P-SB7-FM apart from the standard P-SB7. First, the  P-SB7-FM has been modified to include amplified audio through the mini 20mm built in speaker for the FM frequency sweep. So, the volume on this FM model is twice as loud during the FM sweep than our standard P-SB7 model.

Second, it is specifically designed (de-tuned) to pick up stronger AM frequencies and ignore many of the weaker nuisance frequencies that create radio bit confusion. This means that as the AM sweeps,  individual words will be more pronounced and easier to understand.It is always recommended to use a power amplified speaker when using the SB7. And because we are allocating the majority of the audio power to the FM sweep which is loud and clear, the de-tuned AM sweep requires that a power amplified speaker be used to hear the individual words more clearly.

A good example of this AM sweep modification can be viewed on the most recent Mustang Ranch Ghost Adventures episode. Zak is using AM sweep set to 200msec with an Altec Lansing speaker. You will hear only the intelligent relevant responses to his questions.
