The Gitzo Ball Head Series 4 GH4383QD (screw version) is a heavy-duty tripod head ideal for large telephoto lenses, engineered to ensure the ultimate in smoothness and precision of movement. Though weighing-in at less than 1kg, it securely holds an impressive 30kg load – effortlessly handling a CSC or DSLR equipped with a 400-600mm lens. The unit perfectly complements Gitzo’s Series 3, 4 and 5 Systematic tripods and is available in both lever and screw plate lock configurations. The Ball Head Series 4 has a larger super-smooth coated hollow-sphere ball ensuring confident and comfortable use with heavier equipment, even in extreme conditions and temperatures from -30° to 70°C. It is rich in features: a friction control for precise adjustment and a bubble level to help keep a true horizon. A 360° independent panning lock provides uncompromisingly smooth movement in a fluid cartridge and a short-rotation fast lock assists in getting the perfect shot at a moment’s notice. The whole ensemble is precision manufactured using the highest-quality materials – including high-tolerance steel and aluminum components. The Gitzo Ball Head Series 4 offers unrivaled load capacity, ultra-smooth movement and rapid friction control – all in a sub-1kg unit designed and precision-made in Italy. Supplied with a Gitzo D profile plate, the Ball Head Series 4 is also compatible with Arca-Swiss style plates from other brands.
