Ball Head, QR Plate
The IB2 Triple Action Ball Head is an Arca-type compatible head with a load capacity of 22 lb. It stands 3.9" high, and weighs 14.5 oz. There are separate locks for both the ball movement and the 360° panning motion, as well as a friction control knob. A 90° notch makes it easy to switch to portrait orientation. The numbered scale on the head's base allows for easily repeatable pans, and a bull's eye bubble helps ensure they head is level with the horizon.
