The Sirui BCH-30 Broadcast Video Head, which is designed for mounting bulky, heavyweight cameras, lets you pan and tilt the gear smoothly. It offers a massive payload support of 39.7 lbs, and comes with 3 levels of friction control as well as 13 levels of counter-balance. Both the bubble levels and the SIRUI exclusive top bubble level help in operating the video head effortlessly. The dual safety-lock quick-release platform keeps the camera firmly placed on the head when aligning it. The separate pan-and-tilt locking knobs help prevent movements on their respective axes. Also, the included 100mm leveling half ball allows you to mount this video head on tripods equipped with a 100mm half shell.
