Up your game and lower your score with the Golf Tags Golf Tracking System from GolfPad. Plugging into the top of your golf club just like a ball marker, this device pairs with an app on your smartphone to deliver real-time analysis and results about your game. Using this data from the Golf Tags, you can make adjustments and changes in your swing, stance, and power to get the ball exactly where it needs to go. You can add each club in your bag, view their distances, and even see your stats with each club to make an informed decision for your next swing. The Golf Tags System, which includes 15 tags to be used on all of your clubs, requires no batteries or recharging.
