alchemy V3 Pro

Our Pro line of fins were designed with specific users in mind. Freediving instructors, UW creators, safety divers and globe-trotting adventure-seekers have no need for long fins - they need simplicity, on a grand scale. We managed to pack everything, in terms of performance and efficiency, into a smaller size. Our new compact fins offer all the benefits of the longer versions, with a few extra advantages. Compact size offers great versatility no matter the intended use, as the new length makes the blades a lot faster and easy to manoeuvre under any circumstances. V3 PRO offers maximum performance all the way from pool training to spearfishing or even competitive freediving. Size matters.

These progressive blades feature a 23 degree angle and fit Pathos & Cetma (S-Wing) footpockets. They feature an extraordinary mirror finish on their front side and matt finish on the back. Their unique serial number tag is embedded into their lamination, ensuring the authenticity of your Alchemy product along with a hologram tamper-proof individually numbered tag on your warranty certificate document.

V3-Pro feature the ultimate carbon layer positioning within each blade. Thirteen (13) layers of premium, EU-made, 100% carbon fiber, selected especially for deep sea applications, are positioned in an exceptional way, in order to offer an unbelievable bending profile, with the ultimate feedback, nerve, and speed. Having the first ever V shaped reinforcement layer that goes beyond the blade's angle, raw power comes straight from the beginning of each and every kick.

V3-Pro are manufactured in compliance with the most demanding 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.

V3-Pro blades end in a dolphin tail shape (D.Tail). This shape gives the best performance 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 provides maximum thrust with the least possible energy consumption.

Our 100% silicone hydrodynamic water rails have been designed in a three-dimensional (3D) CAD environment and are produced in the United Kingdom by a high end silicone production facility. Trials and studies in C.F.D. software showed that Alchemy water rails detain and drive the water on the blade, without losing their shape, even in the toughest conditions. 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. Compared to rubber, silicone is far superior when it comes to strength and shape maintenance under extreme conditions.

Choosing the correct stiffness & footpockets for your fins can be a cumbersome experience. Here's how to get it right.

Alchemy fins/blades are produced upon ordering. We do not keep them in stock. Lead time may vary from 5 to 25 working days, depending on work load. Normal lead time is 10 working days. Please be sure to contact us in order to know the waiting time before you place your order.

If you purchase blades with footpockets from our online shop, you will receive a fully assembled pair of fins, ready to use. However, if you only order blades and plan to attach them to footpockets yourself, please keep the following points in mind:

• We only use glue to attach the blades to the footpockets. Please contact us for guidance on how to do it the right way.
• Avoid drilling the blades as it will void the 5-year warranty.
• Let us know the type of footpockets you plan to use as longer or shorter water rails may be necessary.
• Ensure that the end of the footpockets' tendons aligns with the length of the already installed water rails. If footpockets without side tendons or shortened purposely are used, the water rails must be extended accordingly. The side edges of the blades should never be left exposed.

Please reach out to us if you have any further questions or concerns.
