Alchemy S30 Carbon Spearfishing Fins Review By Apnea Passion
A short while ago we were asked by Apnea Passion to send them a pair of Alchemy S30 carbon spearfishing fins to review. Last week they came back wi...
Our spearfishing-only, premium carbon fins take performance and efficiency to a whole new level. Bringing an amazing amount of power to your legs, they go full force, all the time.
Meet the game-changing fins that are designed to enable spearos improve their kicking technique. Demanding oceans and XL fish require power, we can deliver that. The Alchemy S features a unique carbon layering pattern which minimizes the effect of “bicycle” kicking, a common characteristic of nearly all spearos. By its reduction, divers can decent or ascent quicker, thus burning less oxygen. Are you ready to go further? S for Speed, S for Safety, S for Spearfishing.
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 a 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.
S feature the ultimate carbon layer positioning within each blade. Eleven (11) 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.
S 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.
S 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.

The fins is easy to use and carry around while travelling. It has a powerful kick even when it's made of a light material. The pocket is soft and very comfortable.

Without doubt the best fins I ever used. I'm using the S model with M hardness in very different spearfishing scenarios like shallow water with rough seas and waves and also in dives below 30 meters. This model is very versatile with a top performance.
