The improvement for the P-SB7 Rev04 (2018) is that the FM sweep is focused on the frequencies where EVP most often occurs. Hence this gives an improved performance with an increased probability of capturing EVPs.The AM band is unchanged.
The P-SB7 Spirit Box / Ghost Box has been widely used in paranormal TV Shows with remarkable results.The P-SB7 provides responses to questions in real time. When used by a properly trained individual, under certain circumstances, the P-SB 7 will provide results similar that of an EVP recorder.
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.
A seven step adjustable sweep rate provides user flexibility based on individual technique and session circumstances. There are two discreet audio outputs;
A bright EL back light display with manual ON/OFF select is ideal for viewing in the dark. The P-SB7 is intended to be used by professional investigators to help promote the field of Paranormal ITC Research.
Noise cancellation circuit to the FM channel is added and the AM is now equally balanced with the FM so both can be heard. Since added filtering added means lower volume, the P-SB7 now comes with a Amplified Mini Speaker that one attaches easily to its side. This means both FM and AM are heard much better. The reason for the FM Noise Cancellation (NC) is that researchers found that the FM band produces the most communications and the NC makes the FM communications more clear to hear. P-SB7 FM – created with intent of hearing voices from the departed in real time FM and AM frequency sweep.
