From $2,990,000 + VAT or $296,508 for 12 months
The new benchmark for topographic fieldwork. It combines intuitive operation with high performance to deliver a more efficient, accurate, and reliable experience every day.
What makes it unique
Integrated 70 m laser
Built-in laser measurement for fast and safe stakeout without direct access to the point.
Cameras with AR fusion
Augmented visualization that facilitates stakeout and validation directly in the field.
IMU 120°
Wide-angle inertial sensor that allows measuring with tilt without losing accuracy.
Access remote and hard-to-reach
Tilt Compensator
Forget centering the bubble. Measure with the rod tilted to safely reach wall corners or excavation edges.
Visual Layout with Camera
Use the built-in cameras to view the terrain on screen and guide yourself with millimeter precision to the layout point.
Access to Complex Points
Its advanced technology allows measuring in tricky places like deep trenches or near sheds where signal is often lost.
Extreme IP68 Resistance
Fully sealed against dust and water. Ensures project continuity even under torrential rain and harsh conditions.
