The BirdieBall spins exactly like a golf ball. That is why it flies exactly like a golf ball, but for a shorter distance. The reverse spin around the BirdieBall's center of gravity created with the loft of the club (the larger the loft the higher the spin rate) is similar to a golf ball.

When a golf ball “fades” (goes slightly right during its flight) or “slices” (goes far right during its flight) its axis is tilted for a right-handed golfer, from left to right. When it “draws” (goes slightly left during its flight) or “hooks” (goes far left during its flight), its axis is tilted for a right-handed golfer, from right to left.

The non-dimpled surface as well as the straight sides resists flight. The radius on the leading edge and the aerodynamic hole through the center encourages flight and lift. The oscillation between the two as it rotates from air brake to airfoil makes the turbine sound. The lifting aspects help it hang in the air; the braking aspects reduce the distance it travels. The combination of the two makes it a short flight, long hang-time device.

Distance
The BirdieBall has a remarkably satisfying ball flight. It flies just far enough to show ball flight but short enough that you can hit them and retrieve then with minimal effort. Further, because the BirdieBall has golf ball like reverse spin and two flat sides they do not have forward roll when the land, in fact they back up on most surfaces. BirdieBalls fly about 40 yards on average.

Benefits:

• Experiencing the “true feel” and seeing the “true flight” of this amazing practice ball will improve your ability to control a real golf ball.
• The BirdieBall is safer than practicing with a real ball.
• BirdieBalls can be used in small outdoor areas and can even be chipped indoors.
• Limited flight practice golf ball that you can hit anywhere. It's the best golf training aid invented this century. Birdieballs are made of a super polymer and are very durable. PGA 2005 Best and also featured on ESPN!
