Surveying efficiency

2373 Spectra Precision is widening its line of optical survey solutions. There are two additional FOCUS 30 Total Stations now in the range, the new LockNGo and StepDrive models. The LockNGo instrument uses a passive tracking technique that constantly tracks the instrument to the range pole and this is said to improve efficiency by enabling the instrument to constantly lock onto the prism. Precise positioning of all FOCUS 30 Total Station models is provided by the firm's StepDrive motion technology, which is used in the Robotic and LockNGo models and are now available as a stand-alone instrument. StepDrive controls the horizontal and vertical motion of the motors, eliminating the need for traditional motion locks.
