INJIE 5000LRT-X Monocular Laser Rangefinder – Long-Distance 4000m

The 5000LRT-X series adopts a monocular dual-path optical structure (receiving and aiming paths combined, laser emission path independent), enabling fast measurement, auto-focus, and precise distance calculation. It supports average distance calculation and robust data storage. Optional features include azimuth, Bluetooth, GPS positioning, and tilt angle. Compact and easy to operate, it is widely used in rivers, waterways, landmarks, telecommunications, cable lines, geological surveys, meteorology, airports, forestry, border security, construction, and outdoor distance measurement.
