Anunnaki, I will contribute my '2 cents worth'.
Obviously I do not have practical experience with each and every frequency device. However, my experience has changed my life from almost completely DYSfunctional [due to INcurable illness] to functional. I maintain that I will experience 100% remission on my program. My eyesight is better than it was when I was 20 years old - I am 58 - my hearing is near perfect. Hair is not graying, skin is softer and smoother .... etc, etc. I do not take pharmaceuticals of any kind. Not even tylenol.
I will stand on my practical and educated conviction:/b>
Fscan2 supported by Plate-zapping for treatment is superior in the frequency medicine range.
Sychrometer is superior for diagnosis in the absence of an experienced dowser [kinesiology, rods/pendulum] I am a dowser.
Herbs, various Enzymes, certain Amino Acids and Lugol'sIodine are imperative in whole or in part for satisfactory detoxing of die-off in the field of frequency healing.
Each detoxing experience MUST be balanced with a period of building up the bodies resources through nutrition involving excellent foods, supplements and hydration [pure water and unprocessed Sea Salt ].
