Golf GPS rangefinders are used in the sport of golf to aid the player in accurately determining the distance to certain fixed points on a golf course, such as the green or various hazards. They can either be a standalone purpose built device or a piece of software installed on another device, such as a smartphone, which contains GPS capabilities. Especially for higher standard golfers, who will generally have better distance control, there are clear advantages to knowing the precise yardages compared with traditional methods of gauging distance, such as yardage charts and pacing. With the emerging popular wearable, some new Golf GPS devices are emerging, allowing players to measure the quality of their practice, for instance their swing in addition to distance to the hole.
Golf GPS applications for GPS enabled smartphones are becoming increasingly popular as a cheaper alternative to dedicated units.
Laser rangefinders are a competing technology that do not requiring any course data or GPS hardware.
