This is a large statement Pat Flanagan experimental sensor II medallion from 1976. The sensor is fashioned on a 24 inch chain designed to be worn over the heart. The medallion its self is 1.5 inches with 23 Hieroglyphics on the front outer ring. On the back outer ring it reads "1976 PAT FLANAGAN experimental SENSOR II USA" with its Registered 10175." It's a numbered piece. After some research, it's stated, "This powerful toroidal design was used by Dr. Patrick Flanagan in the 1970's and 1980's in the creations of his experimental Sensor Discs. The Sensor was developed by scientifically measuring the cosmic energy which is continually broadcast from the capstone of a properly designed and magnetically aligned pyramid (based on the sacred geometry and physical measurements of the Great Pyramid at Giza, Egypt). The Sensor is a very powerful little device and can effect any living organic material (including humans) in positive and beneficial ways. If one puts a sensor around the neck, the energy level of the carrier raises itself clearly. The sensor can concentrate as much energy as a two meter high pyramid, and works as a resonator for life." Copper in color, minor dulling of chain, in excellent condition otherwise. It is an authentic vintage piece in wearable condition.
