Gitzo G-Lock System

What is Gitzo G-Lock System? The only way to lock and unlock your tripod in a move, with guarantee for stability and sturdiness. G-lock is the innovative evolution of the original twist-lock system: completely redesigned to be faster, stronger and more rigid than its predecessor. Unwanted gaps in between lock parts have been removed to give a rock solid structure to the leg sections, resulting in more clarity and sharpness to your pictures. An added Gravity Lock effect makes the whole system unique: the cone shaped ramp and locking ring work together so that the heavier the load applied vertically to the system is, the stronger the locking effect is going to be.
