In conjunction with the XProb055 a good combination, only in portrait orientation the locking nut is at gewissenen Posititionen in the way because you have to try a little.

No general purpose head so.
BUT: for quick reaction and then fix very well.
And thanks to the removable disk as needed solved very quickly from the stand if necessary.
A good head for starters, and a huge step forward in all areas compared to my old Velbon (stable, higher fixation).
