The Trimble S3 is a professional-grade total station built for contractors and surveyors who need reliable, accurate measurements without unnecessary complexity or cost. With 3-inch angular accuracy (2-inch optional) and a 3,000-meter reflectorless measurement range, the S3 handles everyday survey tasks efficiently, from construction layout to boundary surveys and as-built documentation.
In construction environments, the S3 excels at establishing grade lines, verifying building corner positions, and checking slope compliance. The integrated Trimble SurePoint technology and FineLock pointing system ensure accurate target acquisition and measurement even when working from extended distances or in bright sunlight. Contractors appreciate the straightforward operation—set up the instrument, sight the prism or reflectorless surface, and record data directly to connected survey controllers or field tablets.
The S3's reflectorless capability is particularly valuable for inaccessible measurements—capturing roof lines, bridge clearances, and utility positions without requiring a crew member to position a prism. This single-person operation saves time and improves safety on active job sites. The IP54 rating provides solid protection against dust and light moisture, keeping the instrument operational through typical field conditions. Its compact, lightweight design simplifies transport between project sites and reduces setup time.
Built-in support for Trimble survey controllers and mobile platforms ensures seamless integration into your existing data collection workflow. Whether you're performing real-time stakeout with direct feedback or collecting field measurements for later processing, the S3 delivers the accuracy and reliability professionals depend on.
