1 Coil Multipurpose unit designed to neutralize Electro-Magnetic Fields (EMF) and/or Geopathic Stress. For EMF protection, produces a 7.83 Hz field (Schumann Resonance), blanketing up to 20,000 sq. ft., overcoming negative EMF fields. For Geopathic Stress, unit detects and amplifies the waves, REVERSING in phase by 180 degrees and retransmitting waves, neutralizing waves (similar to noise cancellation technology). Device may be used (1) EMF protection only, (2) Geopathic Stress only, or (3) combination of both. Also addresses HAARP frequencies. This device is a special order item and has a no return/refund policy.
