The IN0 Tripod Ballhead from Benro features an Arca-type compatible quick-release system with an included PU50 QR plate. This head can hold up to 6kg and weighs just 0.26kg. A large locking knob controls the ball’s motion and the 360 panning, and a separate knob adjusts the friction control. Also a numbered scale on the base allows you to accurately repeat pans, and a bubble helps ensure that the head is level.
