Product Overview

A tribrach is an attachment plate used to attach a surveying instrument, such as a theodolite, total station, GNSS antenna or target, to a tripod12. It allows you to achieve more stability while using these instruments2. A tribrach with an optical plummet has a bullseye or crosshair sight that can be used to position the instrument over a survey marker or ground control point3. This process depends on the relationship between the horizontal position and top plate level3. The tribrach with optical plummet is preferred because it works well, reduces the weight and space of the kit, and has less parts that have to be square.
