GeoMax ZG25 AR Visual GNSS RTK Receiver

The GeoMax ZG25 AR Visual GNSS RTK Receiver combines high-precision GNSS positioning with visual-assisted surveying and IMU tilt measurement. Its AR camera can provide image-based guidance for stakeout work, while the calibration-free inertial system allows measurements with a tilted survey pole.

With 1408 GNSS channels, multi-constellation tracking and integrated communication interfaces, the ZG25 is designed for field surveying, construction layout and engineering measurement. RTKSurvey supplies the GeoMax ZG25 for professional surveying equipment requirements.
