Brain Tuner Set of 5

Brain Tuners are based on brain wave studies using electroencephalography (EEG) technology to map different states of consciousness known as Delta, Theta, Alpha, and Beta.
Our tuning forks are made from a special Aluminum Alloy that is heat treated giving them a very pure tone. The single fundamental frequency will remain constant for up to 15-20 years and the non-tarnishing material will not rust or corrode. Each fork is tuned by hand to an accuracy of /- 0.25% or better.
