Excerpt: I use this to take panoramic tours of restaurants and apartments for a few clients. I chose this over Nodal Ninja and a few others because of the geared head. Once you find the "nodal" point (I know there are a lot of people that disagree with that term) the axis of the head will stay put.
Pros: Very sturdy - will lock into position for your focal length and stay there. Forever.
Cons: Very difficult to transport. No built - in level
