Alchemy V3 Carbon Fiber Fins

Heralded as one of Top 3 Carbon Fiber Fins in the World by many deep freedivers, the V3 offers the ground-breaking hard-tip to further improve performance.


Called one of the "Top 3 Carbon Fiber Fins in the World" by 100M Freediver Kurt Chambers, Alchemy improved upon the popular V2Hs and created a fantastic piece of freediving gear.

Carbon Layers
Alchemy V3 offer the ultimate carbon layer positioning inside each blade. Fifteen (15) 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.

Having the first worldwide innovative design of coloured silicone water-rails,we decided to offer more! V3 blades come into two (2) 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 (6) new possible combinations available! In other words, we offer all it takes for you to be in love with your equipment!

General Features & Improvements
Our V3 model comes with all past features as standards and it goes even better! We kept the extraordinary mirror finish on the blades' front side and matte finish on the back. There are also five (5) years of written warranty on the carbon part of your V3 blades ensuring the best working way as the day you first ever tried them! Serial number tag is now embedded into the blade's lamination ensuring the authenticity of your genuine alchemy product along with a hologram tamper-proof individually numbered tag on your warranty certificate!

alchemy V3 Carbon Fiber Blades offer a new revolutionary design with more Carbon Fiber layers for ultimate energy transferring and top performance! alchemy V3 Carbon Fiber Blades are manufactured in compliance with the most demanding and modern standards in constant ambient temperature and humidity. 45 tons of total pressure combined with vacuum assistance (VRTM) and 12 hours post curing in temperatures controlled through PLC (Programmable Logic Controller) with a deviation of less than ± 0,1°C.

Blade ending Shape
alchemy V3 Carbon Fiber 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!

Water Rails
In each alchemy V3 Carbon Fiber blade, there are specially designed water rails made of 100% silicone in white, blue, red or black color. The design was made in a three dimensional (3D) CAD environment and produced in Great Britain by a modern silicone production facility. 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!
