Alchemy carbon bi-fins

Alchemy carbon fiber blades offer a new revolutionary design with more carbon fiber layers for ultimate energy transferring and top performance! Alchemy’s blades are manufactured in compliance with the most demanding and modern standards in constant ambient temperature and humidity. The carbon fiber blades are manufactured with a dolphin tail shape ending of the blades. This shape gives the best results based on hydrodynamics studies 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!

All Alchemy blades are designed water rails made of 100% silicone in different colors. Trials and studies in C.F.D. software showed that this water rail "detains" and drives the water on the blade without losing its shape even in the toughest conditions. The fact that even in the limit bend of the blade, the water rail retains its shape, drives the water from the beginning of the stroke and provides immediate response to the diver's moves. Alchemy water rails offer hydrodynamic design and the absolute superiority of silicone to common rubber on strength, original shape maintenance and strength under extreme conditions!

Available as a pair of blades or as a pair of fins with Pathos foot pockets. Alchemy fins are produced in stiffnesses soft, soft-medium, medium, medium-hard and hard and are compatible with Pathos or Imersion foot pockets. Alchemy carbon fiber blades come with a written warranty of five years!

Alchemy V3 bi-fins – € 485

The Alchemy V3 offers the ultimate carbon layer positioning inside each blade. Fifteen layers of pure 100% carbon fibre 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! Alchemy V3 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.

The V3 blades come into two color variations: V3-Blue & V3-Red! Having both blue and red water-rail colours available along with all the previous versions and a design touch to our logo you have six possible combinations available!
