The PCH Precision Controlled Geared Head from Cambo is a 2.7 lb Arca-type head that has a load capacity of 8.8 lb. Each individual movement has its own locking knob, which allows manual movement when unlocked. The tilt (X-axis) has a lateral tilt of -30° and +110°, which can be moved accurately via the geared knob; and the pivot (Y-axis) can be moved with the same geared accuracy. At the same time, the geared knobs do not move because the gears are self-locking, and all the axes, including the panning Z-axis, rotate over the same point. The 5.1"-tall head can rotate a full 360° at the base, and at the top you will find a secondary rotating base for panoramas. Two spirit levels at the bottom, and two at the top ensure that the head is level when you are photographing a panorama or a virtual reality image.
