Feature:1. Accurate Measurement: Adopting measurement grade high sensitivity GNSS receiver chip. Using a six star system with global coverage. Accuracy can also be ensured in places without mobile phone sign outdoors. Built in pressure gauge elevation measurement, supporting intelligent slope and mountain measurement, making height measurement more accurate.2. Multiple Measurement Modes: Supports 4 measurement modes including area measurement (normal, length width, fixed width, fixed point), distance measurement (normal, fixed point, inclined distance), airborne measurement(rotating airborne, round trip airborne), and slope measurement(ordinary slope, smart slope, mountain) for enhanced accuracy.3. Industrial Grade Safety: Features an industrial grade three proof process, making the land meter water proof, dust proof, and shockproof for long lasting durability.4. Real Time Tracking: View trajectory graphics in real time during use and access saved graphics in the records. Export data easily for analysis and storage.5. Clear Color Screen: Equipped with a 2.4 inch screen for easy viewing in sunlight, this land area meter provides a simple and elegant display with clear visibility.6. Voice Prompts: The land meter offers real time voice prompts in English at a high volume for clear guidance even in noisy environments.7. User Friendly Design: The land meter is designed with large keys for easy use, making it simple to use and easy to navigate for all users.Specification:Item Type: Handheld Land Area MeterMaterial: ABSFunction: S4Positioning Accuracy: Approx. 2.5m / 8.2ftInitial Pressure Calibration: SupportNormal Area Measurement: SupportMountain Measurement: SupportIntelligent Slope Measurement: SupportFixed Point Measurement: SupportFixed Width Area Measurement: SupportOrdinary Distance Measurement: SupportManual Distance Measurement: SupportHeight Display: SupportHeight Measurement: SupportTrajectory Display: SupportUnit Setting: SupportUnit Setting: SupportTime Display: SupportData Statistics: SupportHistory: SupportLighting And Currency Detection: SupportDry Battery: SupportLi Battery: SupportData Storage: 200Voice Broadcasting: SupportData Export: SupportReceiver Chip: High sensitivity GNSS receiver chipReceiver Antenna: Passive large sized planar antennaEfficient Startup: 1 second hot startup and 30 seconds cold startup.Area Accuracy: 0.005acres (0.16-0.5acres), 1% (over 0.5acres) (when HDOP is below 1.0)Distance Accuracy: 1 meter (within 100 meters when HDOP is below 1.0)Functional Features: Latitude and longitude display, altitude display, area measurement, distance measurement, land price calculationData Statistics: Area statistics, distance statisticsArea Records: 200 recordsDistance Records: 200 recordsTrajectory Display: The trajectory will be displayed in real time during the measurement process and can also be viewed in statistical records.Pressure Leveling: about 1 meter (pressure measurement, absolute altitude value needs calibration) (applicable only to S4), about 10 meters (GPS measurement, HDOP within 1.0) (applicable only to S4)HDOP Settings: Customize HDOP SettingsScreen Display: Color screen (2.4 inches)Sound Prompt: Voice broadcastWorking Temperature: -20 to 70 Storage Temperature: -30 to 80 Data Interface: USB interface, which can be used for chargingBattery: 3.7V li ion battery 1800mAh X 1 [shipped with built in battery].Package List:1 x Land Area Measurement Instrument1 x User Manual1 x USB Cable1 x Lanyard
