Ball Head, QR Plate
The IN2 Double Action Ball Head has an Arca-type compatible quick-release system with an included PU60 QR plate. It can hold up to 22 lb, stands 3.8" high, and weighs 14.4 oz. A large locking knob controls the ball's motion and the 360° panning, and a separate knob adjusts the friction control. A numbered scale on the base helps you accurately repeat pans, and a bubble helps ensure that the head is level to the horizon.
