[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.<br><br>Positioning accuracy: ±2.0 m (when HDOP lower than 1.0) Area accuracy: ±0.003 acre(0.16-0.5 acre), ±1%(more than 0.5 acre)(when HDOP below 1.0) Distance accuracy: ±1 m (when HDOP lower than 1.0, 100 m range) Satellite system: Six-star positioning system Area record: 200 Distance record: 200 Waterproof and dustproof: IP65 Working time: 18 hours Function:Normal area measurement, L/W area measurement, Fixed-width area measurement, Fixed point measurement, Circle machine load, Round-trip machine load, Intelligent slope,Intelligent mountain measurement, Normal distance, Fixed-point distance, Slope distance, Fixed point slope distance,Altitude measurement, Barometer, Flashlight, Data export, Real-time update graph, View graphics in record Color: Material: ABS<br><br>Package Contents: 1 x land meter 1 x USB Power cable<br><br>Only the above package content, other products are not included.
