Alchemy V3 Carbon Fiber Fins with Pathos Pockets

Meet the carbon fins which disrupted the freediving world. A complete game-changer, preferred by the sport's deepest freedivers. Paired with Pathos Pockets. Price is for a pair. Complimentary gluing service included when purchased together with pockets. Description Alchemy V3 offer the ultimate carbon layer positioning inside each blade. Fifteen (15) layers of pure 100% carbon fiber positioned in the best possible way to offer the most efficient bending profile, yet the ultimate feedback nerve and speed. Having the first ever V shaped reinforcement layer that goes beyond the blade's angle we make sure power and feedback come straight from the beginning of each kick. V3 carbon freediving blades offer a new pat. pending design called Hardtip. Built in reverse order, we managed to get the blade's tip harder. This all new feature makes the most out of your blade's efficiency as it corrects the total bending profile ensuring zero dead spots during immersion from deep dives. While not taking part in the blade's total stiffness level, comes into action when fins start oscillating continuously during diver's vertical movement, ensuring continuous power transition without dead spots. V3 blades are manufactured ending in a dolphin tail shape (D.Tail). This shape gives the best results based on hydrodynamics studies (Rensselaer Polytechnic Institute / T. Wei) and tests made in C.F.D. software (Computational Fluid Dynamics). The dolphin tail shaped ending gives the maximum thrust with the least possible energy consumption.
