The XB-44 Low Profile Ball Head from Sunwayfoto features a very low center of gravity, very high load capacity (88 lb) and improved ball head design for smoother movements when changing position. It includes the two-drop-notch design for camera orientation, and rubber has been abolished completely--all knobs are now all-metal on the XB-44.
