Designed by Gary Galka of DAS, with Spiritual guidance and influence from Chris Fleming, the Model P-SB7 is the first production built Spirit Box designed exclusively for Paranormal enthusiasts. The P-SB7 made its premier debut on Ghost Adventures "LIVE" show from the Trans-Allegheny Lunatic Asylum on October 30, 2009 where the P-SB7 was used by Chris, a Sensitive, Paranormal Investigator and expert in the Paranormal field. From the moment it was turned ON, The P-SB7 provided "real time" responses to his questions 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 then, it has become very popular and can be seen frequently on Ghost Adventures where Zak continues to receive consistent relevant responses to specific questions. The P-SB7 utilizes a milli-second adjustable Forward or Reverse frequency "sweep" technique coupled with a proprietary high frequency synthetic noise or "white noise" distributed between frequency steps. The New 2011 model now offers an enhanced FM frequency sweep which includes an additional 119 new frequencies from 76MHz to 87.9MHz. No other Hack Box or Modified radio currently offers this. A seven step adjustable sweep rate provides user flexibility based on individual technique and session circumstances. There are two discreet audio outputs; (1) 15mW Earphone, and (1) 250mW Speaker. A bright EL back light display with manual ON/OFF select is ideal for viewing in the dark. The P-SB7 uses three "AAA" batteries. The P-SB7 is intended to be used by professional investigators to help promote the field of Paranormal ITC Research.
