High precision GPS positioning Multi-satellite system support: integrating GPS, BeiDou and other multi-satellite systems, with high positioning accuracy and stable signals, it can quickly lock the position even in complex terrain. Real-time positioning and navigation: provide real-time latitude, longitude, altitude and other data, support path planning and navigation function, convenient for outdoor operation. Area and Distance Measurement Irregular plot measurement: automatically calculates the plot area by collecting coordinate points in a roundabout way or at a fixed point, supporting the switching of units such as mu, square metre and hectare. Distance Measurement Function: It can measure the straight line distance between two points or the path distance between multiple points, which is applicable to the measurement scenarios such as ridge and boundary. Intelligent data processing Data storage and export: Built-in large-capacity storage space can save a large amount of measurement data, and support exporting to computer or mobile phone via USB or Bluetooth, which is convenient for subsequent analysis and management. Graphical display: Equipped with a high-definition colour display, the measurement results are presented in a graphical way, intuitively showing the shape of the plot and the measurement track. Multi-functionality and Portability Multiple Measurement Modes: Support area measurement, distance measurement, track recording, slope measurement and other modes to meet different measurement needs. Lightweight and durable design: the device is compact and lightweight, easy to carry, and the shell is made of waterproof and dustproof material, adapting to the harsh outdoor environment.
