Golf is more than just hitting the ball as far as you can and if you've been trying to improve for so long without seeing real progress, you might want to give Arccos Golf Stat Tracker a shot. It comes with a set of 14 sensors, which can be screwed in to each of your clubs, and synced once to your iPhone to allow it to automatically monitor your whole game. Using GPS and Bluetooth technology, your shots are mapped to a bird's eye view of the course. The stats can be seen on the app right after each shot to help you make better decisions. You can pre-order now at $100 below the retail price.
