A golf rangefinder is a device used by golfers to measure the distance to a specific target on the course, such as the flagstick or a hazard. It typically uses laser technology or GPS to provide accurate distance readings, helping players make informed decisions about club selection and shot strategy. These devices come in various forms, including handheld models and those integrated into golf watches. Many golf rangefinders also feature additional functions, such as slope measurement, which accounts for elevation changes, and some even offer built-in score tracking to enhance the overall golfing experience.
