SIMPLE OPERATION TOTAL STATION The eSurvey E3 is a high-precision manual total station, with accurate angle and distance measurement. It works reliably and delivers precise results even in harsh environments. And its simple operations make most survey and stakeout tasks more efficiently. More Reliable Result Measure angle more accurate, Faster and More Convenient Measurement supported by our absolute encoder Measure more points per day due to and distance, and measure distance faster measurement and stakeout reliability of your measurement more accurate, supported by our (including guide light, trigger key for instant measuring), supported by More Accurate Measurement 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. Use both X-axis and Y-axis Multiple Interfaces High Quality, Designed for Harsh Environments Operate the device even under harsh user can use to update firmware, SD card, and mini-USB that the user can import and export data. environments (like dust, mud, rain, extreme heat, and cold) for many years, supported by its high level of quality.
