Summary: Very high quality heavy duty and large fluid head. Instructions are, as usual, very poorly illustrated. For example hard to see how to open compartment for activating battery which powers LED to illuminate the bubble level indicator. Great for video shooting but a limitation not clearly spelled out is that this is not very good for still photography where you might want to switch from landscape to portrait camera orientation.
Pros: Attaches Firmly, Good Stability, Large Range of Motion, Strong Clamp
Summary: we needed another tripod with head for our video productions. we already have one and needed another for the 2nd camera. the tripod is easy to use. the head has a good fluid movement and is very smooth with its movements. The case that comes with it is good for location and storage when not in use.
Summary: this is a great head for small cameras. it provides added features, like adjustable spring counterbalance control, and a lighted level guage that the original 503 didnt have. it took some time to get smooth rotation in both directions, but with some use, its now very smooth.
