Golf is increasingly digital. We use launch monitors and motion-capture software to understand the numbers and angles that will optimize our distance potential and make our swings more consistent. Heck, some carts even show us a menu for the halfway house on touch-screens as we're driving away from the eighth green. So why pace off distances when GPS technology puts a virtual yardage book in your hands for every point on the golf course? We believe the numbers provided by measurement devices make the game easier and faster. For our review of the top golf GPS devices and watches, we focused on ease of use, range of features and map clarity. Our takeaway: Detailed information delivered quickly and intuitively makes for a better device.
