All Trimble total stations use Autolock® technology to find, track, and lock onto prisms. The Trimble SX12 scanning total station uses a digital camera-based system for its Autolock implementation. One major advantage of the SX12’s camera-based system is that it can better differentiate between multiple reflections within the tracker field of view.
This means when aiming for permanent target installations, the SX12 requires a smaller prism separation than what’s possible with analog trackers. Similarly, when tracking, the SX12 is able to keep following the currently locked target, even when one or more undesired reflective objects come into view of the tracker.
