Feature:1. SENSITIVE RECEPTION: Land meter use a measurement grade high sensitivity gnss receiver chip and use a six star system for global coverage2. MULTIPLE FUNCTIONS: Land meter supports two measurement modes: area measurement(common area) and distance measurement(common distance) Support waypoint acquisition, waypoint navigation, route navigation, trail navigation, lofting navigation Support data export3. HIGH ACCURACY: The land survey meter has a high area measurement accuracy, and the signals are good and easy to search for stars. The outdoor place without mobile phone signals can also ensure the use of accuracy4. LONG LASTING WITH VOICE: Land measure meter adopts industrial three prevention technology, water proof, dusts proof and fall resistant, which is long lasting. With real voice broadcasting(English) and large volume warning, noisy environment can be heard clearly5. DATA RECORDING: Real time view of trail graphics in use, after saving, you can also view graphics in the record The land surveyor area measurement tool has built in barometer elevation measurement for more accurate height measurement6. CLEAR DISPLAY: The land measuring instrument has a large 2.4in black and white screen, simple and generous, clear to read in the sun.
