The SIRUI levelling half ball is used for horizontal alignment of the mounted head. The hassle of aligning tripod legs is a thing of the past. Especially when doing panoramas or when using 3D tripod heads the mounting plate needs to be horizontal.
In addition, video cameras that are used with a video head on the tripod should be mounted on a horizontally-aligned head mounting plate for panning. The 14cm long handle of the SIRUI levelling half ball is an ideal plumb line.
For accurate set-up the half ball can be tilted by +/- 10° to all sides. This pack includes the SIRUI RX-100B 100mm half ball with a handle.
In combination with SIRUI RX-100A half bowl adapter it is perfect for SIRUI tripods R-4213X, R-4214X, R-5214X, R-5214XL. Can be used directly in SIRUI broadcast tripods BCT-3002, BCT-3003, BCT-3202 and BCT-3203.
