The VariZoom Solo Slider Dolly combines the benefits of a track dolly with the portability and flexibility of a slider system. It can accommodate nearly any tripod from heavy-duty 100mm bowl units down to mini tripods or hi-hats. The track consists of five segments for 16 feet of total track. The 16 feet of track yield a travel distance of 13.5 feet. For use on a variety of surfaces, a set of foam underpadding pieces are included to go underneath the track.
