Vivax-Metrotech vLoc3 RTK-Pro is an RTK GNSS utility locator for precision locating and utility-classified survey capture. Surveys are organized by Electric, Gas, Communications, Potable Water, and Reclaimed Water utilities when used with the Loc3-25Tx transmitter.
The Vivax-Metrotech vLoc3 RTK-Pro combines precision utility locating with integrated RTK GNSS positioning to support disciplined survey capture during active locate operations. The system is designed for operators who require both signal-based locating and spatially accurate utility documentation within a single platform.
The vLoc3 RTK-Pro supports multiple locating modes used to interpret signal behavior and utility alignment, including Peak and Null locating, Vector Locate guidance, Transverse Graph analysis, Plan View visualization, and dedicated Sonde locating. These modes provide directional, graphical, and field-shape feedback to assess locate quality and signal distortion during operation.
