Spring LockThe new center SADL (Spring Assisted Double Lock) is a patent pending system that combines two locking systems in one, that maximizes both locking power and ball smoothness. A high friction metal guarantees a high efficiency lock, the PTFE bushing controlled by a pre loaded spring maximizes smoothness and control. Safe GripsSafe Grip is a material that gives a safer lock between your camera and the head plate, preventing the camera from moving or slipping. It is used on quick release plates and in applications where the camera equipment is screwed to the support to reduce pivoting and twisting. Safe Lock Safe Lock is a special techno polymer that maximises locking torque and equipment stabilisation. It is used on the upper discs of tripods and heads, and in applications where the equipment is rotated and screwed onto the support to eliminate micro movements and vibration. Seperate Pan ControlWhen using a ball head, the ability to lock and unlock the panoramic movement independent of front-back or lateral tilt movements is convenient for panoramic photography and when a high level of control is required. Friction Control By fine tuning the freedom of movement of the head, friction control makes the head slower and more precise or faster and looser. This feature also helps to make using heavy equipment or long lenses safer. On ball and fluid head models without separate friction controls, slowly adjusting the lock knobs gives similar results. Leveling Bubble The new leveling system made of three independent leveling bubbles on the quick release plate and one in the ball stem, always guarantee perfectly leveled images. The problem that affects many high quality heads in the market regarding drift angle is absolutely minimized with an outstanding value of 0,03°. Double Quick Release Safety SystemThe system consists of two pins, one fixed and one manually operated by means of a button, that prevent camera equipment from suddenly dropping out of the head when the quick release locking knob is released. Extremely useful with heavy equipment, long lenses and spotting scopes. Bubble BallGitzo has now developed a new exclusive technology that enables us to produce high quality, completely round hollow spheres, with a ultra thin wall, for an incredible weight reduction. Gitzo Bubble Ball also features a perfected PTFE treatment that further reduces the surface micro roughness for the ultimate shooting experience and accuracy.
