Overview

More Accurate Measurement

Measure angle more accurately, supported by our absolute encoder and distance, and measure distance more accurately, supported by our powerful EDM unit.

Rich Software Applications

Experience rich applications, including offsets, tie distance, area & volume, remote height, reference line/arc, construction, and 2D road, to meet your field measurement needs.

Faster and More Convenient Measurement

Measure more points per day due to faster measurement and stakeout (including guide light, and trigger key for instant measuring), supported by our comprehensive and user-friendly software.

High Quality, Designed for Harsh Environments

Operate the device even under harsh environments (like dust, mud, rain, extreme heat, and cold) for many years, supported by its high level of quality.

More Reliable Result

Use both X-axis and Y-axis compensators to ensure the reliability of your measurement result.

Multiple Interfaces

Supports RS-232C(6-pin). The user can update firmware and SD card, and mini-USB that the user can import and export data.
