1. Multi-function measurement: The rangefinder supports multiple measurement modes, including height measurement, angle measurement, distance measurement, speed measurement, scanning measurement, two-point height measurement, span measurement, azimuth angle, etc. Whether it is outdoor measurement or indoor use, it can meet different measurement needs. 2. High-precision measurement: laser technology ensures high-precision measurement results. It can measure angles in the range of -90° to +90°, and provides centimeter-level measurement accuracy, which can meet the measurement tasks with high precision requirements. 3. Safe laser wavelength: The range finder uses CLASS1 (class one) laser with a wavelength of 905 nanometers. This laser is eye-safe and invisible, so there is no need to worry about harming human eyes when using it. 4. Transparent liquid crystal display: The equipment is equipped with a transparent liquid crystal display, which can clearly display the measurement data and parameters, making the measurement results intuitively visible. Users can quickly obtain the information they need. 5. Angle calibration and unit switching: The rangefinder provides angle calibration and unit switching functions. The unit can be switched by long pressing the power button and the mode button, and it is easy to switch between different units such as meters, yards, and feet. In HD mode, press and hold the mode button for 2 seconds to enter the angle calibration state. After the calibration is completed, the angle will be 0° when the measuring device is kept horizontal to ensure the accuracy of the measurement. To sum up, this handheld high-precision laser rangefinder has a variety of measurement modes, including height measurement, angle measurement, distance measurement and speed measurement, etc., using a safe 905 nanometer laser. Equipped with a transparent LCD display and unit switching function, it is convenient for users to operate and view results. In addition, the angle calibration function ensures the accuracy of the measurement. This distance meter is a full-featured, simple and practical outdoor measuring tool.
