Our V3-30 carbon freediving fins come with all past features as standard, plus more. New shape fits C4-300 and C4-400 footpockets and the angle changed into radius of 30 degrees (V3 model has 23 degrees sharp corner angle). New shape and angle offer more leverage and combined with the extra 3 degrees that the footpockets offer, effective angle totals 33 degrees. This change offers an “early start” of the blade’s working spectrum and makes the blade feel softer than it really is. We kept the extraordinary mirror finish on the blades' front side and matte finish on the back. There is also a five (5) year warranty from the day of manufacturing for the carbon part of your 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 document.
Alchemy V3-30 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.
V3-30 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.
Having the first worldwide innovative design of colored silicone water-rails, V3-30 blades come into lots of color variations, including metallics and fluorescent options as well. In other words, we offer all it takes for you to be in love with your equipment.
Alchemy V3-30 carbon fiber blades offer a new revolutionary design with more carbon fiber layers, for ultimate energy transferring and top performance. They 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
V3-30 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.
In each Alchemy V3-30 carbon fiber blade, there are specially designed water rails made of 100% silicone in white, blue, red, black, gold, silver or fluorescent colors. The design was made in a three-dimensional (3D) CAD environment and produced in United Kingdom by a high end 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.

SEE THE ALCHEMY FOREST!
Very efficient, it is not easy for me to find the correct size of foot pockets, I am always between 2 sizes. The C4-400 is fine, the carbon is just awesome and the fins are light. Classy expensive fins. Top world class efficiency. As a freediver instructor, I test sometimes the fins's students. Alchemy is another world clearly.
Amazing product, it feels like I don't have any fins on but the propulsion of them is out of this world. Tried them with c4 300 and 400 foot pocket, in my opinion the v330 and the 300 foot pocketis the perfect pairing.
The best fins I have tried, very comfortable and very light.
These fins are a game changer! I owned a lovely pair of V3 before, but these are entirely different. I have the new blade fitted with the C4-400 foot pockets. They are amazingly light and responsive, but the angle makes a huge difference. They feel very easy on your legs and make longer swims way more efficient in terms of lactic build up. Perfect competition fins, for a great balance of power to work - I am really happy with them!
Some of the best fins I've had the pleasure of using. The response and power you can receive from these fins while exerting less energy is a game changer for anyone.
I love these fins! They've completely changed my diving experience and I find myself pushing further knowing I have the right gear.
Having tested different brands, Alchemy v3 is one of the top tier selection when choosing good carbon fins. Little effort needed to fin, while giving an efficient amount of propulsion compared with other carbons. Distribution workload of carbon layers feels very well distributed. Alchemy fins is also one of the lighter weight fins to carry. The 15-30% efficiency increase makes alchemy a good choice.
It's an amazing fin.
I really love that good quality. This is my second fins of my life. After i tested this product i feel i found the best one for me.
