The HO Sport RAD Disc (The Round Aquatic Device) allows anyone, regardless of skill level, to participate in a day behind the boat. You can put the handle in the soft EVA handle hook, sit, stand or kneel, and away you go. The riding possibilities are endless, opening up a world of pure imagination on for your friends and family. Fun for all ages, the RADs are guaranteed to turn some heads this summer. For a more advanced ride go with the smaller size disc.
