The Black Healer Harmonizer[BHH]
Regular Harmonizer creates a torus shape field around itself where "negative", unbalanced and often noxious vibrations get neutralized or at least moderated. The "Black" edition ads nano material to the surface that greatly expands the reach and also allows easy programming.
The idea was inspired by the research of the Keshe Foundation and it incorporates copper coils individually covered with layers of nano material and its action is based on the interaction between magnetic and gravitational fields, I don't believe it was ever tried in dowsing and energy work and the results are quite intriguing and it may become a new standard in energy tools.
It's 50X30mm (~2X1") and it weighs 39g (1.38oz).
