So in your experience. Rife machine are generally NOT effective and zappers ARE? I'm not trying to start an argument, I am a relatively inexperienced person just trying to learn more.
I have been close to taking the plunge on a 2700 dollar bcx ultra plasma rife machine for the past couple weeks, just so expensive.
I think you would be better off with an F165. Because the F165 uses positive offset square wave by default. So you don't have to hit the exact frequency to get some results. It also can generate a carrier wave for better penetration.
With a plasma hard to tell exactly what strength of signal you are getting to the target area. Rife used a directional Xray tube.
