The AquaBound Sting Ray Carbon Posi-Lok kayak paddle is designed to provide superior performance with low swing weight by combining a carbon shaft with carbon abX II blades. The Aqua Bound Sting Ray in all carbon is a lightweight, all-purpose paddle with a blade shape that is silky smooth through the water. Carbon reinforced abX blades and carbon shaft give this paddle an incredibly low swing weight and is unbeatable at this price! Features the Posi-Lok adjustable ferrule system or with standard (three hole with snap button) ferrule system. Posi-Lok is an adjustable ferrule system which allows the paddle to be feathered at several angles and makes adjustability on the fly a breeze. Left handed paddlers, or paddlers who enjoy changing the angle of the paddle to suit the conditions, will like the versatility of the Posi-Lok ferrule system. Simply pinch the dual-button release and twist to your desired feather angle. The ferrule clicks firmly into the lock position to achieve a rock solid connection with no play whatsoever. The Posi-Lok ferrule does NOT allow for changes to the length of the paddle.
