P-GB11 is a virtual version of the famous P-SB11 the Spirit Box that paranormal investigators use the most.

There is + and - control buttons for each channel - for both the FM and AM channel. One can scan both channels at the same time and choose directions independently for the scanning of each channel - forward and backward. Scanning speeds can be adjusted to several different levels from slow all the way up to very fast.

The volume can be controlled independently for each of the two channels. There is also a mute button. Some users prefer to not use an antenna and therefore there is an on/off button for the antenna.

There is also a very useful MUTE button for when the investigator wants to ask a question.
