• 2.8-inch large color screen, 320x240 dot matrix, clearer

• You can measure the area and perimeter of parcels of any shape, including mountains and slopes

• You can measure the ground length (i.e. length or distance) of two points or any path

• Measurements, graph tracking and prices are automatically calculated after the measurement is complete

• The measurement methods are divided into automatic, manual, constant width and vehicle-mounted

• Save and record 100 historical data and graph tracks. You can browse, view and delete history at any time

• It can set the unit price of area, unit price of length, conversion factor of mu value and square meter, and can set automatic and manual measurement methods

Note:

• 1. This instrument is suitable for measurement in outdoor open areas, do not get close to tall blocking objects (for example: high-rise buildings).

• 2. Wait until the instrument has found more than 6 satellites before starting the measurement.

• 3. It is not recommended to measure small areas less than 0.3 mu.

• 4. When measuring, the motion paths should not intersect or overlap.

• 5. When measuring a small area, due to the small number of acquisition points, the displayed graphs and curves may be inconsistent after optimization by the program preset algorithm, which is a normal phenomenon.

• 6. It is best to wait until the latitude and longitude coordinates displayed on the screen are stable before starting the measurement.
