The medium-sized G20 geared head can be finely adjusted in three axes and features a clamping mount on top for standard Arca-Swiss plates. The head can support a weight of up to 20 kg and weighs 680 g itself. It has a height of 80 mm and a diameter of 75 mm. The geared operation allows for highly precise adjustments of plus/minus 15° in two axes. Unlike the smaller G2 model, it has a horizontal 360° panning axis both on the top and bottom. The two spirit levels, along with the laser-engraved all-around scale, aid in precise work. The metal parts are made from high-quality 6061-T6 aluminum, with magnesium and silicon as alloying components. This corrosion-resistant material is characterized by high strength and good toughness.
