Benro IN1 Double Action Ball Head for Camera Tripod Photography
The IN1 Double Action Ball Head from Benro has an Arca-type compatible quick-release system with an included PU60 QR plate. It can hold up to 17 lb, stands 3.4" high, and weighs 11.2 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.
