The Dio-Mid reaches up to 60 Yards through walls, floors and ceilings.
It will protect an entire area from micro wave signals, electric lines and low level radiations. It does't need to be faced true north.
The frame transmits the diode efect from a plate in the wood base through the Tetrahedronal frame work. It must be at least 3 feet from walls and large furniture to work most efficiently.
The Crystal Transmitters will broadcast up to 8 feet. Amythyst, Quartz, and sliced colorful crystaline bases amplify the diode effect.
The figurines are lead free pewter.
The Crystals were created by Mother Nature and will vary in color, shape and size.
