Introduction
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.


  • Precision Laser Measurement up to 50m
  • Long-focus Camera
  • Integrated Handheld Ergonomic Design
  • HD Touchscreen Display
  • Comprehensive 3D measurement
  • Real-time Visualization of Laser Points
  • Quick One-Tap Measurement
  • Multiple Measurement Experience
01
Laser Technology
The fusion of GNSS, IMU and laser technologies pushes working efficiency to the limits and ensures accuracy.
02
Full-Constellation & Multi-Frequency
With 1590 channels and 50+ satellite tracking capabilities, Mercury also supports PPP service. Getting fixed in seconds boosts your productivity.
03
Auto-IMU
Mercury is equipped with Auto-IMU, eliminating the need for manual initialization, supporting automatic calibration, and streamlining the operations in the field. It continues to support 120° compensation in conventional, laser and visual modes.
04
Handheld Design, Easy to Carry
Mercury is ergonomically designed for easy carrying. The GNSS receiver with sophisticated structure minimizes user fatigue.
05
Robust Design
Built to IP68 standards, Mercury is waterproof and dustproof, completely workable even in harsh environments.
06
Visual Stakeout
3D visual view on Survey Master software. By simply following the directional arrow and real-time distance, with the stakeout point marked directly on the ground.
