The Birdie Putt Green Reader by BuddyBirdie is an on field putting aid and golf training aid that is designed to help you visualize the slope of the green during game or training. You do not need to guess the slope of the green by simple 3 steps. Place it on a green. Aim towards the cup with an arrow on the top of the product. Read a bubble in the center. It can visualize not only slopes on green such as uphill, down hill, break left or right but also angle of the slope with increments.
