Kronk Boomerangs are very light and aerodynamic for an easy toss return, or they can be thrown fast for the Fast Catch competition event. It is recommended for ages 13+ years old and is light enough for throwers with less than average arm strength. As a Fast Catch boomerang it can come back at you pretty quickly so this is not for young children. It is a great returner though, very light and very aerodynamic. This is a professionally molded plastic Fast Catch boomerang of 10" x 9.5" dimensions which should be in any competitor's bag. It doesn't have to be used for competitions though as it is a great hobby boomerang as well. This is a RIGHT HANDED boomerang only.
