Just a Silly post showing the innards of the A9 as seen via a Hi Rez CT Scan. Despite how light it is no, it isn’t just a battery, blinking light, & placebo effect LOL

Back Story: I am a recent newcomer and huge proponent of PEMF, and more specifically ICES PEMF. It is just such an amazing modality and technology, that I am compelled to share it with most everyone I meet. My work colleague Kevin, with whom I travel the world, likes to joke that I am the next Jim Jones starting a cult 
Yesterday we were helping a local engineer in Geneve with an upgrade while we had a day between major projects, and I noticed he was walking a little back on his heels so I asked if his back was bothering him. He said no, his knee. Well of course I just had to share my ICES PEMF “Testimony” 
Later I strapped a pair of stacked coils on his knee 
and set him up with my A9. He was happy to give anything a try that might offer some relief. It was a long night… we worked until just after 2AM local time so I sent him to his hotel with the A9 still on and a freshly charged battery. the next day we were all working and again my colleague (we will call him Kevin) asks him if he feels like it has helped, to which the local guy says yes, absolutely. Kevin chuckles and says “you know, it’s really just a black box with a blinking light & battery that Colin uses to play pranks on people” 
guy looks at me and I say he’s just talking trash, then I realize… we can scan it! Later we do and the link above is the result, Cheers
