A digital rangefinder is an electronic device used to measure distances accurately. It works by emitting a laser beam that reflects off a target and returns to the device, calculating the distance based on the time it takes for the light to travel. Digital rangefinders are commonly used in various fields, including surveying, construction, and sports like golf. These devices often feature a digital display that shows the measured distance in real-time. Many modern digital rangefinders also include additional features such as angle measurement, area calculation, and memory functions, making them versatile tools for professionals and enthusiasts alike.
