A golf rangefinder is a device that measures the distance to a target, typically a flag or the hole, by emitting a laser beam and measuring the time it takes for the beam to reflect back to the device. This information can be used to help golfers select the appropriate club for their shot, as well as to more accurately gauge the distance to the target.
Golf rangefinders have become increasingly popular in recent years, as they can provide golfers with a significant advantage on the course. By knowing the exact distance to the target, golfers can make more informed decisions about their shots, which can lead to lower scores and improved performance. In addition, rangefinders can also be used to measure the distance to hazards, such as bunkers and water hazards, which can help golfers to avoid these hazards and improve their overall course management.
