External LCD display allows for real-time data reading without needing to look through the eyepiece. Ideal for foggy mornings, rainy weather, and low-light conditions. Integrated with seven advanced modes, including slope measurement (on/off), angle and height detection, speed measurement, horizontal distance, two-point vertical measurement, and 2-second flagpole lock. Flagpole locking system detects flags up to 200 yards (flag only) and 300 yards (when the flag is unfolded), with vibration alert to confirm lock-on accuracy. Features an advanced laser time-of-flight algorithm and multi-echo analysis for fast and reliable focusing, with precision accuracy of ±0.5 yards. The 6x magnification lens and adjustable focal length offer clear image quality and stable targeting, even at longer ranges. Built-in 1000mAh rechargeable battery powers up to 20,000 measurements per charge. USB Type-C port enables fast charging. Auto shut-off activates after 16 seconds of inactivity to preserve battery life. Designed for multi-scenario use including golf, hunting, mountaineering, and construction measurement. Operates smoothly under cloudy, rainy, foggy, and low-light conditions. Built-in magnetic stripe allows for quick attachment to golf carts or metallic surfaces for hands-free accessibility.
