The Gitzo Series 3 GH3780QD Center Ball Head with Bubble Sphere is a magnesium ball head with a quick release plate that incorporates many innovative features. It is designed to match the range of high performance tripods available from Gitzo. A large locking knob controls the movement of the ball, while a separate lock controls the 360deg. panning motion. In the center of the locking knob is a tension, or friction control dial that allows you adjust the tension of the ball to match the weight of your gear.
The Spring Assisted Double Lock combines two locking systems in one to maximize locking power and ball smoothness. A double quick-release safety system consists of two safety pins to protect your camera from falling from the head when the locking knob is released.
