The efficiency of the F-SW derives from the powerful and individually selectable energy range. The device's shockwave source is equipped with a cylindrical coil and offers a high energy dynamic in the entire focus zone. The two stand-offs provide different treatment options. The shorter the stand-off head, the greater the penetration depth. The longer the head, the smaller the penetration depth.
 
Stand-off I (short): Focal zone: 15-45mm; Therapeutic Effectiveness: 0-105mm
