I am looking for a "brainwave machine" that induces an electrical current through earclips. NOT a biofeedback machine or a machine that doesn`t connect with earclips. The machine must have a precise setting available of
7.8 or 7.83. This has been called the Schumann resonance and some imagine that it is the frequency of the earth. Does anyone have an "alpha pacer 1" for sale? For some reason the alpha pacer 2 is ineffective.Thanks. Laurence
