The Trimble Optical Tribrach with Optical Plummet is an essential accessory for professional surveyors and contractors who demand precision instrument setup in the field. This tribrach provides the foundation for accurate total station and GNSS antenna positioning on survey control points, ensuring your measurements start from the correct position.
Precision centering is critical in surveying and construction layout work. The Trimble Tribrach features an optical plummet that allows operators to center instruments vertically over survey marks with ±0.3mm accuracy, eliminating setup errors that can compound throughout your project. The precision leveling screws ensure your instrument is perfectly plumb, which is essential for accurate angle and distance measurements with total stations or consistent signal reception with GNSS antennas.
Built with a standard 5/8-11 base thread and designed to fit 60mm flat base instruments, this tribrach is compatible with Trimble's complete range of survey equipment. The durable optical plummet remains accurate through thousands of setups, providing reliable performance whether you're working on boundary surveys, construction staking, or machine control setup.
