From Slim's Words

" The coils are basically energetic vacuum cleaners. They such and blow. Dark energy is pulled up through the south pole of the Coil, transmuted to light, and blown out through the north pole of the device. "

"The distance factor is a big thing with the Coil. As the Coil is moved further away from the point of pain, the sucking action increases and the healing effect is stronger. According to Hartmut Muller's Gravity Wave Theory( Standing Gravity Wave of The Universe), gravitational pull is actually more powerful the further away you get from something. "

" The gold and silver add their own special frequencies to the over all tensor effect. As they interact with the tensor field, each element sublimates off the copper wire in its monatomic from introducing nano-particles of gold and/or silver into the healing equation."

Well, these can be also applied to your hands as another Coil.
