The Practitioner Activator can be comfortably worn around the leg to strike your tuning fork. This tool is perfect for therapists working around tables and in locations where it is inconvenient to carry a table top activator. The Practitioner Activator comes with quality elastic strapping that won't loosen or slip, a buckle that closes and releases easily, and a rubber surface for "activating" tuning forks. Designed for professional use. Tuning fork not included.
