A device or application designed to measure distances on a golf course assists players in determining the distance to the target (green, hazards, etc.) from their current position. These tools can range from simple handheld devices using GPS or laser technology to sophisticated software integrated into smartwatches or smartphone apps. For example, a laser rangefinder can pinpoint the exact distance to the flagstick, while a GPS app might display the layout of the hole and distances to various points.
Accurate distance measurement is critical for successful golf. Knowing the precise yardage allows players to select the appropriate club and execute their shots with greater confidence and precision. This knowledge can significantly improve performance by reducing scores and enhancing overall enjoyment of the game. While traditionally, course markers and printed yardage guides offered estimations, modern technology provides far more precise and convenient solutions. This evolution has made distance measurement accessible to a wider range of players, contributing to the strategic depth of the sport.
