This tripod is absolutely stable on every ground. Contrary to conventional tripods, it does not stand on three but on four legs. Precise balancing of the tripod is realized by an integrated spherical calotte from igus®, which links the outer shells with two legs each. Through the extreme pivoting capability of the spherical calotte it is also possible to work very close to the floor, which is often required especially in the macro photography. Additional advantage: The calotte does not need to be lubricated and is nevertheless smooth running.
