Topcon Tribrachs-10/20 are recommended for accurate plumbing of Topcon total stations, EDM's, theodolites, and reflector systems.

The tribrachs have a circular level of 10'/2mm sensitivity. The units also have a three leveling screw system for quick leveling, a 5/8" x 11 thread for attaching to the tripod and a single lock lever for a fast set up and tear down of instruments.

The Tribrach-10 incorporates an optical plummet telescope with 2.2X magnification. The image is erect and can be utilized to achieve a quick set up in the field. The reticle pattern of the optical plummet telescope is an easy read to circle and dot pattern.
