The Usopp-X03K Laser Rangefinder is a high-performance device built around our proprietary 1535nm erbium-glass laser, fully compliant with Class 1 eye-safety standards. Compact and lightweight, it is designed for single-operator outdoor use, with a quick-release mechanism and excellent adaptability to various environments. Key features include single-point and continuous ranging, laser indication, ballistic computation, environmental measurements (temperature, humidity, air pressure), an LED display, battery level indicator, Bluetooth data transmission, and serial port communication. Integrated environmental sensors deliver real-time data, enhancing accuracy and decision-making in long-range precision shooting and hunting scenarios. With outstanding ranging capabilities—up to 4,000 meters for reflective targets, 2,500 meters for trees, and 1,500 meters for deer—the Usopp-X03K also supports custom ballistic curves, wind direction capture, and built-in range card generation. It is a cutting-edge shooting aid that bridges the gap between instinct and ballistic science.
