[Easy to measure land area] Multiple measurement modes meet the measurement needs of different land environments: Normal mode, mountain mode, intelligent slope mode, length and width mode, fixed width mode, fixed point mode, circle machine load, round-trip machine load, and so on. [Real-time display of measurement graphics] Real-time display of measurement graphics during measurement to accurate measurement of area and easy to find and store. [High measurement accuracy] It can that the error is less than 1% when measuring more than 2,000 square meters of land. [Intelligent identification of slopes and mountains] No need to manually measure the slope value of the measured land, one-click intelligent identification of the current slope, to measurement accuracy and reduce errors.
