The Spectra Precision DG813 Upgrade Kit is engineered for contractors and survey crews already operating the DG613 who need to step up to advanced digital measurement capability without the cost of a full instrument replacement. This factory-authorized field upgrade delivers the core enhancements of the DG813 platform — sharper digital display, faster angle readout, and refined targeting precision — directly to your existing instrument investment. Whether you're running layout on a commercial build, performing boundary work, or managing grade control, the DG813 upgrade brings your instrument up to current jobsite demands.
Overview & Jobsite Applications
Modern construction and survey workflows demand faster setups, more reliable readouts, and data that integrates cleanly into project documentation. The DG813 upgrade addresses each of these pressure points. The enhanced digital display eliminates the ambiguity of older readouts in bright sunlight or low-light conditions, while improved angle measurement functions reduce the time spent on each setup. Crews working horizontal and vertical angle layouts on multi-story structures benefit from the tighter precision tolerances, and survey parties handling property boundary re-establishment will appreciate the improved repeatability of angle observations. The upgrade is designed to be completed in the field or at a service depot, minimizing instrument downtime.
