The 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 maneuver under any circumstances and the reinforced base of the blades offers maximum results for all diving styles. Following the V330 model, their shape fits various 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.
