Sokkia 724034 Tribrach with Laser Plummet - Black

Professional Tribrach with Laser Plummet for Accurate Instrument Setup

The Sokkia 724034 tribrach with laser plummet is engineered for survey crews and construction layout professionals who need fast, reliable instrument centering on every setup. Featuring a precision laser plummet in place of a traditional optical eyepiece, this tribrach projects a visible red laser beam directly to the ground point, allowing for quicker and more confident centering—even in bright outdoor conditions. Whether you're running control traverses, setting up total stations for boundary surveys, or positioning GNSS antennas on control marks, the 724034 delivers the mechanical consistency and centering accuracy that professional workflows demand.

Overview & Jobsite Applications

Designed to Sokkia's exacting manufacturing standards, the 724034 tribrach pairs with a wide range of Sokkia and compatible third-party instruments through its standard 5/8" x 11 thread and flat-plate mounting interface. The three leveling footscrews are machined for smooth, backlash-free adjustment, making precise leveling fast even in cold or gloved-hand conditions. The laser plummet eliminates the awkward crouching required with traditional optical plummets, reducing setup fatigue on long field days. Crew chiefs setting up instrument networks or layout crews working from known control points will find this tribrach saves meaningful time at each setup station.

Job Applications

Boundary & Topographic Surveys: Set up your total station precisely over a control monument in seconds using the laser plummet, reducing time spent at each instrument station during traverse work or topo data collection.

Construction Layout: Position instruments accurately over layout control points on active job sites where speed and repeatability are critical to keeping crews productive and minimizing costly errors.

GNSS Base Station Setup: Mount GNSS antennas directly to the tribrach over a known benchmark for precise base-rover RTK workflows, ensuring your baseline is anchored with confidence.

Control Network Establishment: Use the 724034 as part of a forced-centering system with multiple tribrachs to efficiently move instruments and targets between setups without re-centering from scratch.

Frequently Asked Questions

Is the Sokkia 724034 compatible with non-Sokkia instruments?

The 724034 uses a standard 5/8" x 11 threaded mounting interface, which is common across many surveying instruments. However, always verify the specific adapter requirements for your instrument model before purchase, as some manufacturers use proprietary mounting systems.

Does the laser plummet require batteries?

Yes, the laser plummet requires a power source—typically small batteries housed within the tribrach body. Check the included documentation or contact us for specific battery type requirements for this model.

Can this tribrach be used for forced-centering setups?

Yes. The 724034 is designed for use in forced-centering workflows where the tribrach remains fixed on the tripod and instruments or targets are swapped between stations, saving setup time and maintaining centering accuracy throughout a traverse.

What is the centering accuracy of the laser plummet?

Sokkia laser plummets are engineered to provide centering accuracy consistent with professional survey-grade standards. For exact centering tolerance specifications, refer to the product documentation or contact our technical team for support.
