This kit consists of the 509HD video head and 545B aluminum tripod with spike foot shoe and bag. The 509HD video head features an exclusive Manfrotto patent, Bridging Technology, which allows for greater load capacity as well as revolutionary performance levels. The "bridge" design also assists the PAN friction control to be more intuitive and easy to set while protecting against any knocks that may occur during the recording process. The 509HD's FDS (Fluid Drag System) is variable and directly controls action and resistance on both axes; the ergonomics of the controls have been noticeably improved to make use of the FDS even easier. Another unique feature is the ABR (Advanced Balance Recorder). This new patented electronic solution permits the head to record the perfect balance position of the equipment and recall it any time. By using LED lights controlled by a proximity sensor, it is easy to quickly slide the camera to the previously set perfect balance. The 545B is a two stage, twin leg, lightweight aluminum professional video tripod. Due to optimization of the upper and lower collars, the tripod guarantees more torsion rigidity and payload (55 lbs.), plus improved shooting performance. The die cast aluminum crown features a built-in 100mm interface bowl, which can be adapted to a 75mm if needed. The tripod is equipped with floor-level spreader. Technical Specifications: Maximum Load Capacity 28.6lb; Minimum Height 18.7in; Maximum Height 68.3in; System Weight 17.8lb.
