Our Geo-Measure Optical Plummet Tribrach is a key instrument in the sub-millimetre positioning that we promise. Attached to a tripod, you can fasten any instrument on this Tribrach, whether it be a Total Station, GNSS Receiver or Prism Assembly by just twisting the locking handle. This Tribrach is compatible with the GeoMeasure Rotating Tribrach Adapter with Brass Insert.
