We love these light and easy to throw "Tech" boomerangs. Molded for the exact airfoils needed and made from optional materials to adjust the weights for different wind conditions, throwing strengths and tunability, Tech boomerangs are an excellent foundational boomerang for any beginning thrower over the age of 12. The Tech Yellow is made from colorful ABS plastic to give it very low weight and these boomerangs are about as easy to see in the air as you can get! They spin like a top and are a very easy return.
