The Sonic Slider™ is a custom made weighted fork created by Biofield Tuning founder Eileen McKusick. Its frequency of 93.96 Hz is the 12th harmonic of the 7.83 Hz Schumann resonance, or background electromagnetic pulse present in the earth's atmosphere.

Users report a wide range of benefits including a reduction of pain and tension, improved digestion, support for weight loss, improved muscle tone, a healthier and more radiant complexion, an increase in energy and overall well being, and more.

With an extra long handle and a pleasing frequency, the Sonic Slider is designed to have the handle slide along the face, neck and body. Only available at Biofield Tuning. 

Your purchase includes a PDF instructional booklet with links to demonstration videos. This PDF is immediately available in your digital library for download upon purchase.

We suggest the use of the Striker Block for easy activation.

We sell two types of tuning fork activators to get the maximum performance from your weighted and unweighted forks.

Watch this video for instructions on the best way to activate your tuning forks.

To clean your Biofield Tuning forks, we recommend using warm soapy water (hand or dish detergent work equally well).

Use a soft-bristle toothbrush to clean divots and interiors. Lay upright on a dry paper towel to allow water droplets to depart from crevices.

Be sure to pat dry after washing to avoid discoloration.

Use alcohol wipes for easy disinfection in between uses.

Biofield Tuning forks are manufactured in America with a premium aluminum alloy and a proprietary finishing process that minimizes absorption into the skin, maximizes sustained vibration, and extends fork life.

After having many forks fail during tuning sessions, Eileen worked for years to develop a premium alloy that would better withstand the stress that Biofield Tuning places on forks. This alloy proved to be the most resilient while maintaining our high standards for clear, sustained working tones.

This alloy produces audible overtones in our unweighted forks and sustained vibrations/frequencies in our weighted forks, which are critical elements in producing optimal results in Biofield Tuning.

Our metal accessories contain nickel. The Circuit and Contour Boots are made of stainless steel, which contains a very small amount of nickel to achieve its corrosion resistant properties (similar to the amount found in a stainless steel spoon or fork). Our Handle Extender is aluminum and is plated in nickel to create a corrosion resistant barrier between the metal and its environment.

If you have a slight allergy to nickel, you may wish to try this product: Nickel Guard - No Nickel - Protective Coating Solution for Nickel Objects (or another similar product).

For those with a higher sensitivity to nickel, we suggest avoiding the Handle Extender, and instead recommend the stainless-steel Contour Boot or the Circuit Boot.
