Golf GPS watches connect to satellites to map out a golf course and show distances to any of its locations. Users tap the screen to show yardage to a certain point of the course, and the watch calculates this distance and displays it on the screen. Connected to the GPS systems, these watches are also made with high-end technology and programming to analyze shot success and keep the score. Most of the watches can be operated without too much tech knowledge based on the physical buttons or tap controls.
