503HDV 特点
精心手动安装的内置气泡水平仪可让您实现万无一失的水平校准   两个弹簧产生的重锤均可以进行平衡调校，这使得承载各种重量相机的云台操控性能更为出色。   适用于精细控制云台运动的可调阻尼   摇摄杆rosettes（介于于云台和摇摄杆之间的齿形盘）可以更换——如果反复使用日益磨损锯齿并减少了摇摄杆和云台之间的咬合力，此时只需更换rosette即可。

The 503HDV has a completely new ergonomic, easy-to-use, functional design; features include large ergonomic locks and knobs allowing for a more solid grip and better control. For enhanced ease of use, the tilt lock and friction controls are located on the left side of the head.It has an improved and adjustable counterbalance capacity: a switch controls the different counterbalance settings, allowing the user to adjust the system to accommodate various payloads for different filming needs. The counterbalance system can be adjusted to four positions ensuring both smoother tilt movements and greater equipment safety. In addition, it has an illuminated levelling bubble - making it easy for shooters to level the camera in low-light conditions. In addition to the old 503, the 503HDV has also a replaceable pan bar rosette.
