Through years of research and numerous prototypes this latest leap forward in EVP ITC technology has emerged. Through its ability to scan between kHz frequencies and the identification of the frequencies with the best chances for communications, a blend of 40 frequencies have been combined to a sweet spot for the most flowing communication ever experienced though an ITC device. The user is able to slow the scanning speeds down to as low as 30 mS and also set their custom desired length of the frequency interval steps for the sweep frequency. The device can be operated in a silent mode and will then only be starting to scan when a REM field sensor and/or an IR sensor are triggered. When a trigger happens scanning suddenly starts for a few seconds (you can set the length of time), which allows for communication to come through. This allow more of a normal communication through the device rather than listening to constant scanning noise. There is a REM touch pad that you use with a new technique where you tap the pad while scanning. This method has shown an increase in the number of EVP messages coming through. This amazing EVP receiver also comes with Automatic Temperature Deviation technology which alerts you of sudden temp changes of 5 degrees Fahrenheit or more. It also has ambient temperature. There is a built-in flashlight and the display has a red backlight. The internal speaker is a premium sound 2 Watts audio speaker. You can as an alternative, to using the internal speaker, connect the PSB7 PRO with an audio cord to a Portal device such as the Para4ce Portal V5 or a speaker with capacity up to 250mW.
