We realize there are cheaper Tuning forks available on the internet (especially from India and China) and we encourage you to read below before purchasing a cheaper set.
The tuning forks sold by SomaEnergetics are manufactured in the United States with Aluminum from the United States. The manufacturer has decades of experience making the highest quality tuning forks. They are precisely tuned within 0.5% of the indicated frequency at 72 degrees. All tuning forks are subjected to inspection processes to guarantee quality. The specially designed aluminum alloy makes them harder, more durable, and impact resistant with decreased frequency changes due to temperature variations. This results in a longer ring tone, purer tonal quality when tapped individually, and a complete range of overtones when tapped together. Excessive wear or misuse will void any frequency warranty. DIngs: yes - Dents: No!
Aluminum tuning forks tested from other companies are softer, have higher levels of impurities, and are more susceptible to corrosion and frequency changes due to temperature variations. They have a rougher appearance, the ring time is 20+% less, and tonal quality, which is important in the healing process, can vary by 2+%. Due to the softness of the aluminum many overtones, which are essential in neural transmission as part of stress reduction are dropped and cannot be relied upon with any consistency. The companies supplying the softer impure aluminum tuning forks tend to have weak environment records and questionable labor practices.
