Sonic Slider® Weighted Tuning Fork
A specialised weighted tuning fork for bringing vibration, sound and tactile resonance into professional facial massage.
Created by Biofield Tuning founder Eileen McKusick, the Sonic Slider® is hand-tuned to 93.96 Hz and designed with an elongated handle that allows the vibration of the fork to be applied directly through the skin.
The 93.96 Hz frequency is described by Biofield Tuning as the 12th harmonic of approximately 7.83 Hz, commonly associated with the fundamental Schumann Resonance present within the Earth's electromagnetic environment.
Sound + Vibration
Frequency: 93.96 Hz

The weighted design allows vibration to travel through the point of contact, creating a very different sensory experience from sound instruments used solely around the body.

Professional Care
Clean the tuning fork and attachment between clients using an appropriate professional hygiene protocol.
Biofield Tuning advises that its tuning forks and accessories can be cleaned with warm water and hand or dish soap, then dried thoroughly. Alcohol wipes may also be used for convenient disinfection between clients.
Avoid dropping or striking the fork against hard surfaces, as this can damage the instrument or affect its tuning.
Store securely in a clean, dry environment when not in use.
