Geoleni Twist Focus Tribrach Without Optical Plummet Yellow

Geoleni Tribrachs offer precise plumbing of surveying instruments and adapters and have a universal 5/8-11 base plate. The Geoleni tribrachs provide movement that is always smooth and free of play, even after years of use. The precise alignment of the support area to the base plate of the instrument assures extremely accurate forced centering. The optical plummet is so robust that adjustment during the entire lifetime of the tribrach is practically unnecessary. Its construction predestines the tribrach for all applications, including extreme temperatures as well as high dust and humidity.
