• Description

  V3-30 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.

  These groundbreaking blades feature a 30 degree angle. Such an angle requires less effort from the diver when kicking, which practically translates to less oxygen consumption. Combined with the extra 3 degrees that C4 (300 & 400) foot pockets offer, the fins’ effective angle totals 33 degrees. This combination offers an “early start” of the blades’ working spectrum and makes them feel softer than they really are. The blades also feature an extraordinary mirror finish on their front side and matt finish on the back. Their unique serial number tag is embedded into the blades’ lamination, ensuring the authenticity of your Alchemy product along with a hologram tamper-proof individually numbered tag on your warranty certificate document.

  V3-30 PRO 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.
