The UBH 45X Ball Head with Bidirectional Clamp from Uniqball is a combination leveling base, pan/tilt head, and ball head. It has a unique design that incorporates an outer ball with a bubble to level the clamp, and an inner ball for panning and tilting. Once the outer ball has been leveled and locked, the inner ball will only move on the Y-axis, maintaining level pans. The head can also be used as a conventional ball head with a full range of movement by locking the inner ball and only using the outer ball.
The UBH 45X stands 4.1" high, and can hold up to 88.2 lb. It has an Arca-type compatible clamp that works with quick-release plates, as well as most other Arca-type plates. The head's clamp is oriented on the Y-axis so that you can slide the plate front-to-back to balance your camera when using a long lens. A hex key is included to allow you rotate the clamp 90°. The head comes with a carrying case to protect the head when it is not in use.
