Thanks to this technology carbon fibre strands are impregnated perfectly in resin without the risk of forming micro bubble kicks and with an optimal distribution of the resin itself. In addition the percentage of necessary resin is reduced considerably with a great increase in performance characteristics of the blade. The specific carbon fibre strand used was developed specifically for the manufacturing of freediving fins. The under lying result is a very comfortable fin, in part thanks to the thermo rubber foot pockets, providing high performance for the diver. The Stingray carbon blades push the diver to the fullest during descents and ascents even at great depts.
