Dino Discs are designed for small children that are unable to throw very far. They perform best for people who throw golf discs less than 150 feet. In most instances they are appropriate for kids age10 and under, but it depends on the child. Some 12 year old’s will prefer a Dino Disc to a normal weight disc. Some nine year old’s will see increased performance with a heavier disc. Many women and senior citizens prefer the ultra light weight Dino Discs over traditional golf discs.
