It is my honor and good fortune to serve you. 【Ball Head with Wonderful Precision Machining】: All metal parts are machined from aircraft aluminum alloy by a 4-axis CNC lathe with a machining accuracy of 0.03mm. The surface of the ball head is treated with oxidation technology, which has a very smooth feel, high durability for long-term use, and combines weather resistance to withstand harsh environments and the beauty of a tool. 【Panoramic Photography at Various Angles】: The ball head has a 360-degree panoramic base and a single lock, allowing you to set up your camera at any angle you like, and there is no fear of your equipment suddenly falling. The panning base has 0° to 360° index marks laser-engraved. With a bubble level that can measure both vertical and horizontal directions simultaneously, you can easily check the horizontal tilt situation. With a horizontal rotation knob and angle rotation scale at the bottom of the ball head, you can make fine angle adjustments during shooting, which is useful for subtle panoramic compositions. 【Camera mounting screw is 1/4", tripod mounting screw is 3/8"】
