Built to keep layout moving. 

 The Trimble ST30 smart target pairs a 360° prism with built-in tilt compensation and active tracking, so you spend less time leveling and re-aiming and more time setting points. Whether you are running a stakeout, verifying as-builts, or reaching a point overhead, the ST30 is engineered for accurate, dependable results on busy, demanding jobsites.

Trimble ST30 Smart Target

With technology designed to boost accuracy, minimize errors, and maximize efficiency, the Trimble ST30 smart target helps you complete design stakeouts and as-built verifications faster.

Trimble Inertial Platform™ (TIP™) IMU-powered tilt compensation means you no longer need to level the rod for every shot, which speeds up topographic surveys and stakeout tasks. Measure on the ground or above your head, right side up or upside down. Tilt-compensated shots eliminate bubble and human handling errors, and let you reach previously inaccessible points like building corners, inverts, and overhead structures without the complexity of COGO offsets.

Trimble active tracking and target ID keep you on the right prism. If line of sight is interrupted, Trimble GeoLock™ technology uses built-in Trimble RTX® corrections to regain lock automatically, with no manual searching or lost time, even on the busiest worksites. RTX corrections for GeoLock come standard, no subscription required.

The 360° prism has a rugged exterior and protected active tracking LEDs for dependable performance in all environments. The ST30 is rigorously drop-tested and vibration-tested, and IP-rated for dust and water protection.
