Thanks for the reply. True, these devices are too expensive. I have had a bio-resonance feedback scan but kept on picking up obvious things like lung, some specific bone etc, which wasn't specifically an ailment. It was good though in picking up that i had an allergic reaction to mouse piss. hahah. Anyway, the reason Im interested in a frequency generator is so that i can do my own testing as an aid for my friends and others once I have mastered its diagnostic method. The mini fg looks like it can do the job for $300. I just wanted to know if anyone here has had an experience with it.
