RIFE SET - THE BIG FOUR
The frequencies of 727, 787, 800, & 880 Hz were used widely by Dr. Royal Rife. He used these frequencies in combination with other frequencies for many resonance therapies. He called them the All Healing Frequencies, and considered them 'The Big Four.'
This set contains all of the 'Big Four' forks in one pouch. We recommend a wooden mallet for best activation of these short forks.
All of our high quality tuning forks are Made in the USA. Each fork is triple tuned for accuracy of +/- .25% Hz. A protective velvet pouch is included.
