A rangefinder is a device that measures the distance to a target. In golf, a rangefinder can be used to measure the distance to the hole, or to hazards such as bunkers and water. This information can be helpful in club selection and shot planning.
There are two main types of rangefinders: laser rangefinders and GPS rangefinders. Laser rangefinders emit a laser beam at the target and measure the time it takes for the beam to return. GPS rangefinders use the Global Positioning System (GPS) to determine the distance to the target. Both types of rangefinders have their own advantages and disadvantages.
