Description:

The iconic V3-30 are the go-to performers for deep freediving applications. A product of collaboration with some of the world’s deepest humans and utilising next generation materials and supreme craftsmanship, they are the most powerful pair of fins we’ve ever made. Armed with lightning fast response, they are designed to outdo competition even in the most demanding scenarios.

Features:
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 a 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.

Carbon Layers:

V3-30 feature the ultimate carbon layer positioning within each blade. Fifteen (15) 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.

Hard Tip:
V3-30 are equipped with a groundbreaking pat. pending design, Hardtip™. Built in reverse order, we managed to get the blade’s tip harder, and maximised efficiency by correcting the total bending profile, thus ensuring zero dead spots during immersion. While it doesn’t affect the blade’s overall stiffness level, Hardtip™ kicks in when the fins start oscillating continuously during a diver’s vertical movement, ensuring continuous power transition without energy loss.

Water Rails:

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.

Lead Time:

Alchemy fins/blades are produced upon ordering. We do not keep them in stock. Lead time may vary from 3-5 weeks, depending on work load. Please be sure to contact us in order to know the waiting time before you place your order.

Construction

V3-30 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.

Blade Ending Shape

V3-30 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.
