All technologies must contain some form of light to receive government approval, and that's where the comparison ends. Em-Probe scientists were the first in the Us given permission to study monochromatic light in 1982 and IT DIDN' T WORK then, and it doesn't work now for any thing deeper than skin.We proved that in scientific experiments and reported it to FDA in 1985. Static magnets are the same because they are limited to the skin surface only, that's what STATIC means. Light is the same there are no magic windows because the skin contains large proteins that absorb light like a sponge. - bet you never heard of a sun burned muscle! Empulse technology is pure energy, doesn't get absorbed by the skin,
