Mercury Laser RTK sets a new standard in surveying with true Pole-Free operation. Powered by the next-generation K9 chip and advanced IMU algorithms, it delivers high-precision measurements without a survey pole or controller, combining laser technology with real-time visualization. This all-in-one device integrates a high-performance geodetic antenna, long-range laser, and high-definition camera for accurate measurements up to 50 meters. Its ergonomic handheld design, touch-screen, and quick measurement button provide comfortable, efficient operation even in complex environments.
