The BioResonance PRO Pendant in Sterling Silver is the preferred choice for individuals looking for comprehensive protection against all types of environmental stress including EMF related challenges. Typical concerns include geopathic stress above underground waterveins, earth fault lines and natural grid systems such as the Benker grid, Hartmann grid, Curry grid, but also larger grids such as the 250 Meter, the 400 Meter grid system and even Moon Stripes. It also shields the body against the chaos created by electromagnetic fields (EMFs) from wireless routers, smart meters, phones, computers and other electronics.
