Each actuator is equipped with a magnetic coupling that enables the operator to interchange different sized and shaped transducers. This allows to adapt each treatment to the specific case, becoming more targeted when treating trigger points or covering a larger area in case of stimuli to the locomotor system. Deeper when treating patients with abundant fat located in the areas to be treated. More comfortable when dealing with variable surfaces. The instrument comes with 3 sizes for each actuator: flat 50 mm, flat 30 mm, hemispherical 16 mm.
