Players of all skill levels can throw the Aerobie Superdisc well and enjoy its stable, accurate flights. Conventional flying discs have their center of aerodynamic lift near the disc's leading edge in flight, which makes them roll to the right for right handed throws and to the left for left handed throws. By contrast, the Aerobie Superdisc's breakthrough spoiler rim centers the disc's aerodynamic lift throughout each flight, making the it a more stable flyer for throwers of all skill levels. The Aerobie Superdisc's soft, rubber edge provides a great grip for strong throws and remains smooth to catch even after landing on pavement. Made from non-toxic materials, the Aerobie Superdisc's soft edge is also kind to a dog's mouth, making it the disc of choice for many professional dog disc entertainers. The Aerobie Superdisc also floats in water, making it fun for the beach or the pool. The Aerobie Superdisc measures 10 inches in diameter, and is recommended for ages 8 and up.
