Gives independent pan control to ballheads that don't have it, so you can move solely the left-right axis without affecting the orientation of the ball itself. Has a built-in bubble level. Great for use with Magic Ball & Mini Magic Ball. Comes with a standard Euro 3/8"-16 hole in the bottom but also has a reducer bushing to convert it to the smaller 1/4"-20 thread size.
