Tribrach with Optical Plummet
Attaches surveying instruments (theodolites, total stations, GNSS receivers) to a tripod, allowing them to be repeatedly placed in the same position over a surveying marker point.
The built-in optical plummet provides sub-millimetre precision when centring the surveying instrument over the ground marker.
