  • Description

    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.

    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.

    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.
