The technology using the principals of pulsed magnetic waves goes back many years and has since branched off into numerous and rapidly changing/expanding techniques and products. I don't know that what I'm referring you to is technically classified as MWO-technology, but it's definitely related and I hope worth your while in reading about.
PAPIMI is the buzzword and it seems as though it may be the latest and greatest product to have spun off from previous generations of MWO-like R&D.
On second thought, here is a link to a more traditional type of MWO equipment IE> somewhat older technology, but old in this sense does not mean old as we usually think of it; instead, old means about 1 to 3 years old technology, given how rapidly this stuff is evolving into newer and newer products. If you follow the links to products you will find price information. None of the products that I've referenced - both the above links and the one below, is cheap stuff.
