SitePro 03-LPR122 360° Robotic Prism System with +28.1 mm Offset

The SitePro 03-LPR122 is a professional-grade 360° robotic prism engineered for seamless compatibility with Leica total station systems. With a precision +28.1mm prism offset that matches Leica specifications exactly, this prism eliminates the need for manual offset corrections on every shot — saving time, reducing errors, and keeping your crew moving. Whether you're driving grade stakes, setting control points, or doing as-built verification, the 03-LPR122 delivers the all-around tracking performance that demanding survey and construction professionals rely on.

Overview & Jobsite Applications

The SitePro 03-LPR122 is built for one-person robotic workflows. The 360° glass prism allows the total station to continuously track the rod person from any direction without repositioning the prism face. This makes it ideal for open construction sites, corridor surveys, and utility layout where the rodman is constantly moving and changing direction. The durable housing is designed to withstand the rigors of daily field use, and the precision-ground glass ensures consistent, repeatable measurements shot after shot.

Key Features

• Exact Leica Offset Match: +28.1mm constant eliminates the need for manual corrections on Leica-compatible instruments
• 360° Tracking: Continuous lock-on from any horizontal direction — no need to face the instrument
• Precision Optics: Ground glass prism delivers accurate, repeatable reflections for reliable EDM measurements
• Rugged Field Housing: Built to survive drops, dust, and daily construction site abuse
• Versatile Mounting: Compatible with standard survey poles and bipods via 5/8" x 11 thread
• One-Person Operation: Designed to maximize efficiency for robotic total station solo workflows

Job Applications

Construction Layout: Set building corners, column lines, and utility offsets with a single rodman and robotic total station. The 360° tracking keeps the instrument locked on through direction changes and obstacles.

Topographic Survey: Collect terrain data efficiently across large sites. The rodman can move freely without orienting the prism face, dramatically increasing points-per-hour on topo shoots.

As-Built Verification: Confirm installed structure locations against design coordinates. Consistent offset matching with Leica instruments ensures every check shot is trustworthy.

Utility & Pipeline Corridor Work: Track along alignments, roads, and easements where the rodman is constantly moving away from and back toward the instrument.

Frequently Asked Questions

Is the SitePro 03-LPR122 compatible with all Leica robotic total stations?

The 03-LPR122 is designed with a +28.1mm offset to match Leica prism specifications. It is compatible with Leica robotic total station models that use standard 360° prism tracking. Always verify the prism constant setting in your instrument before beginning a survey.

What does the +28.1mm prism offset mean and why does it matter?

The prism offset (or prism constant) is the correction value applied to account for the optical center of the prism not being at the physical face. Using the correct offset matching your instrument's expectation — in this case +28.1mm for Leica systems — ensures every measured distance is accurate without requiring manual corrections in the field.

Can I use this prism with non-Leica total stations?

The 03-LPR122 can be used with other total station brands, but you must manually enter the +28.1mm prism constant into the instrument settings. Failing to input the correct constant will result in systematic distance errors on every measurement. Consult your instrument manual for how to set a custom prism constant.

Does this prism come with a carrying case or pole?

The SitePro 03-LPR122 is sold as a prism unit. Poles, bipods, and carrying cases are available separately. See the compatible accessories listed above for recommended pairings available at Express Tools.
