Faster and more convenient measurement
Measure more points per day due to faster measurement and stakeout (including guide light, trigger key for instant measuring), supported by our comprehensive and user-friendly software.
More reliable result
Use both X-axis and Y-axis compensators to ensure the reliability of your measurement result.
Rich software applications
Experience rich applications, including offsets, tie distance, area & volume, remote height, reference line/arc, construction and 2D road, to meet your filed measurement needs.
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.
