The improvement for the P-SB7 Rev05 (2020)
* Improved internal speaker
No need for additional speaker, however the unit still has a socket should you choose to use it or plug strait in to a portal unit.
* Built-in ATDD function (Automatic Temperature Deviation Detection)
When the ATDD is activated it will calibrate to current temp, when one pushes the Baseline button, and then alert with audio and visual display when temp changes with + or – 5F. It will confirm and alert you of a sudden temperature drop or increase.
* The background color of the screen has changed to RED
RED is night vision friendly. It is also a bit brighter so it makes it easier to see in the dark. As before the background light can be turned off.
* The SB7T has a built-in ,white high intensity mini led light that acts as a flashlight.
* The AM sweep rates are no longer faster than the FM Sweep rates.
They are now both set at the 6 different preferred sweep rates to choose from: 100, 150, 200, 250, 300, 350 milliseconds (ms).
* A new updated AM Signal Boost circuit!
This means that one now hears more radio detail in the AM bandwidth.
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 six step adjustable sweep rate provides user flexibility based on individual technique and session circumstances.
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.
