Critically, GPS devices do not vary that much in terms of accuracy, so, what makes them different from one another? Plainly, what makes devices different are the features, speed and convenient, and cost. First, features like large, vibrant touchscreens, shot, performance, and fitness tracking, and hole mapping may be important for some players. Second, how quickly a device operates and where it can be stored are important. Third, how much a device costs and what a golfers is getting for that money should be considered. Other important features include what distances the device provides. Almost every unit will deliver distances to the front, middle, and backs of the greens. The best units will also provide distances to hazards including water and bunker areas and do so on a large, easy-to-see display.
