Purchased in the spring of 2024. Used for 3 rounds (used infrequently as it was used in conjunction with a GPS watch). Maximum measurement distance: 1000M, 0.06-second fast measurement, measurement error ±0.5M. Features include pin lock function, vibration alarm, slope mode, magnetic function, and IP54 waterproof and dustproof (splashproof level). Smaller than a business card, approximately 9.26 x 3.4 x 4.7cm, ultra-compact size. 118g. Competition-compliant model, equipped with a slope function that can be confirmed by fellow golfers. Instantly measures elevation difference and angle, showing the true distance to hit. You can instantly switch between modes depending on the situation, such as when you want to measure the straight-line distance or the distance considering the elevation difference. Suitable for both uphill and downhill courses. The pin lock function avoids measurement errors even when there are many trees or grass in the background of the pin when measuring the pin from a distance, allowing you to accurately aim at the target and measure the distance. The measurement speed is fast, quickly locking onto the flagstick, and notifying you with a vibration when the target is identified. No battery replacement required, fully charged (USB-C) for approximately 15,000 measurements. Automatically turns off after approximately 30 seconds of inactivity to conserve power. Built-in magnet for easy attachment to golf carts and clubs. No claims and no returns accepted.
