Leica Professional Precise Traverse Set with Optical Plummets

The Leica Professional Precise Traverse Set is an elite surveying solution engineered for high-order geodetic networks. Featuring ultra-precise GDF322 tribrachs, a high-contrast target plate, and a GPR121 professional circular prism, it delivers the sub-millimeter centering repeatability required for critical engineering and structural monitoring.

Sub-Millimeter Forced Centering: Allows the seamless swapping of total stations and targets on a fixed tripod setup, completely removing centering errors from the traverse math.
GDF322 Torsional Stiffness: Includes professional-grade tribrachs with integrated optical plummets, designed to remain perfectly rigid under heavy automated total stations.
GPR121 Premium Optics: Features a copper-coated circular prism that maximizes EDM signal return, offering superior distance accuracy and range in all atmospheric conditions.
Ruggedized System Transport: Supplied with a heavy-duty GVP738 site case featuring precise cutout compartments to keep sensitive optical carriers, plummets, and prisms secure.

Full Description

The Leica Professional Precise Traverse Set represents the pinnacle of optical positioning technology, specifically curated for surveyors establishing primary control networks or monitoring sensitive structures. Built on the principle of forced centering, this kit eliminates station setup discrepancies by enabling total stations and prism targets to be interchanged seamlessly on a fixed tripod base. This workflow ensures that the strict mathematical integrity of your traverse loop is maintained across every setup. This precise variant incorporates Leica’s highest-grade components, starting with the GDF322 professional tribrach, which features an integrated optical plummet and industry-leading torsional stiffness to prevent drift under heavy instrument loads. The target assembly pairs the GPR121 professional circular prism-boasting specialised anti-reflective coatings for maximum distance range-with a high-visibility target plate for rapid pointing. Delivered in a robust, custom-foam GVP738 hard container, this set provides the definitive, field-ready toolkit for high-accuracy data acquisition.

FAQs

What components make up the Professional Precise Traverse Set?

The standard configuration includes two GDF322 tribrachs with integrated optical plummets, two GRT144 carriers, two GPR121 professional circular prisms with target plates, and a GVP738 rugged transport case.

What is the difference between this Professional Precise kit and the Leica Basic Traverse kit with optical plummets?

The Professional Precise kit features GDF322 tribrachs with superior torsional stiffness and integrated optical plummets, alongside premium GPR121 copper-coated prisms with metal targets.

What is the centering accuracy of this precise setup?

When using the forced centering method with the GDF322 tribrach and GRT144 carrier, the position repeatability is kept to a sub-millimeter level, typically under 0.5mm.

What is the prism constant for the GPR121 prism?

The Leica GPR121 has an absolute Leica prism constant of 0.0mm, ensuring seamless plug-and-play measurement calculations with Leica total stations.

Can this traverse kit be used with other instrument brands?

Yes, it is fully compatible with any total station brand using a standard wild stub mount, provided you configure the 0.0mm Leica constant in your settings.

Why is an integrated optical plummet preferred over a laser plummet?

Optical plummets in the tribrach base do not require battery power, remain highly visible in bright direct sunlight, and offer excellent long-term calibration stability in harsh field environments.

How does the forced centering workflow save time on site?

Once a tripod and tribrach are leveled and centered over a point, they remain untouched; prisms and total stations are simply clicked in and out, reducing setup times by half.

What is the purpose of the anti-reflex coating on the prism?

The specialised coating prevents deceptive signal reflections from the front surface of the glass, ensuring the total station measures directly to the internal corner-cube apex.

How should the optical plummets be checked for accuracy?

You can perform a quick field check by setting up over a point and rotating the tribrach 180 degrees; if the crosshairs stay centered, the plummet is in calibration.

Is a tripod included with this specific set?

Tripods are typically sold separately or as a bundle addon, with heavy-duty wooden tripods like the Leica GST20-9 highly recommended to match the precision of this kit.
