The GF-Bangi is a mobile camera tracking and panning rig for use on dollies, camera cars, tables, stages etc.
When working off a dolly it enables stable, off-set tracking shots and positioning of the camera. It is also very useful for table top shots and for getting the camera in and out of tight spaces such as windows, car doors etc.
The length of the standard tracking tubes for dolly shots is 1m (3′3″) long but a 2m (6′6″) set is also available for use as a tracking rig.
