Advantage

Intelligent Electronic Auto-Leveling System

Ultra-Long Working Distance and Stable Laser Output

All models feature advanced electronic leveling technology (gyroscope + multiple individual electronic sensors), with a leveling range of ±5°. This enables fast and automatic self-leveling, effectively eliminating manual errors and significantly improving construction efficiency and precision.

The entire series offers a working diameter of ≥800m (with LP500 Basic receiver), combined with consistent laser rotation speeds. This fully meets the demands of large-area and long-distance construction projects, delivering efficient performance both indoors and outdoors.

Wide Range of Models for Different Applications

Robust and Durable Protective Design

From mini prisms (12.7mm / 17.8mm) to standard and 64mm high-precision prisms, the product range covers diverse surveying needs. Whether for compact setups, general measurement, or long-range applications up to 1500 meters, users can select the ideal model for their specific project requirements.

The full series achieves IP64/IP65 protection ratings for dust and water resistance, along with drop protection from 0.5m to 1.5m (main unit only). The sturdy body and professional packaging guarantee long-term stable performance in demanding construction environments.
