The PB343-27 Powerball Ball Head with 3 Controls and Arca Type Quick Release from Davis & Sanford provides three control knobs for ball tension control, ball lock and 360º panning movements. The separate controls allow smooth, precise positioning and firm locking. An Arca-Swiss style quick release enables you to easily remove the camera from the head and a safety lock helps prevent miscues that can damage your camera. A standard base with 3/8-16" screw thread is compatible with most tripods and monopods and with a load capacity of 27 lb, this head will hold almost any camera and lens combination including videocameras, medium format, DSLR, mirrorless and point and shoots. Two bubble levels allow for even alignment and precise composition.
