Say hello to our ground-breaking new fins that are progressive in every way. With top notch performance and configurability, they are designed to enable a wide range of spearos push the boundaries of what is possible. Every aspect of the Alchemy S30 are designed in pursuit of greatness. Based on a completely new blueprint which aims to help spearos outperform themselves even in the most extreme scenarios, they are engineered to go full force, all the time. From there anything is possible. S for Speed, S for Safety, S for Spearfishing.


Our S30 model is the latest addition to the Alchemy family. Tailor made for spearfishing, it packs everything, in terms of performance & efficiency, into an advanced specialty. The new length (-3cm compared to V330) makes the blades a lot faster & easy to manoeuvre under any circumstances and the reinforced base of the blades offers maximum results for all diving styles. Following the V330 model, their shape fits C4-300 & C4-400 footpockets with an angle of 30 degrees. We kept the extraordinary mirror finish on the blades' front side and matte finish on the back. 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.


Having the first worldwide innovative design of coloured silicone water-rails, we decided to offer more. Alchemy S30 blades come with an extra unique colour, never seen before in the alchemy pallete; Tuna Blue Metallic. The previous colour variations, are also available. In other words, we offer all it takes for you to be in constant love with your equipment.


Alchemy S30 Carbon Fiber Blades offer a new revolutionary design with 11 (eleven) Carbon Fiber layers for ultimate energy transferring and top performance. Alchemy S30 Carbon Fiber Blades are manufactured in compliance with the most demanding and modern standards in constant ambient temperature and humidity. 40 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.


Alchemy S30 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.


In each alchemy S30 Carbon Fiber blade, there are specially designed water rails made of 100% silicone. 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.

The make, length, flexibility, strength of the fins are amazing. I bought it though it was meant for spearfishing but I use it for depth training, teaching and fun dive and I can say amazing fins. Never doubt Alchemy products at all.

Usually, i use V330 for doing spearfishing and freediving. Recently, i turned to S30. It's different but i don't regret my choice. They are more in adequation with my spearfishing style. Good handmade construction and nice packaging with the serial number for the 5 years warranty! You can go on it with closed eyes!!!

Lightest and toughest fins in the game! I always get compliments by other divers fascinated with how light Weight my alchemy S30s are paired with c4 300 Foot pockets. I can go all day swimming the blue on long shore dives with no problems. Love the performance and the look! The bar has been set high!

Best fins I've ever had! Especially being rare to have on Guam.

Great fins, almost feels like I'm not wearing them. Does the job very well. Two things to note. The pockets weren't glued to the blades very well. I have to glue the rails again. The pockets are also a tad loose.
