If you want a measuring device that does everything that you want it to do, then the Garmin Approach S80 is the device for you. It doesn’t just measure distances on the course, it can also be used as a game improvement tool when you are practising. It has a built-in launch monitor mode which allows you to find out your clubhead speed, ball speed, swing distance and estimated distance. It can also measure your swing tempo to ensure that you are swinging the club at the optimum pace for you. The device has four practice/game modes that help you to groove your swing. You are also to play against other golfing friends with that competitive edge being honed.
