Alchemy V3-30 Fin Blades – high-performance carbon fins for freediving
are premium carbon fin blades designed for advanced freediving and performance-demanding spearfishing. They are well known for their multi-layer carbon construction, fast energy return, and excellent flexibility — ideal for divers seeking deeper dives or higher swimming speeds.
Key features
- Blade made from 15 layers of 100% high-quality carbon fiber, delivering superior durability and responsiveness compared to other blade types.
- Approximately 30° blade angle helps reduce energy consumption while finning and generates powerful thrust from the very first kick.
- “Dolphin tail” blade shape optimizes thrust based on hydrodynamic principles, reducing energy loss during deep dives.
- 3D silicone water rails help maintain stable water flow across the blade, improving efficiency with each kick.
- Blade length of approximately 80 cm and width of about 19.5 cm provide an excellent balance between propulsion and underwater control.
Benefits in use
– Multi-layer carbon structure delivers strong propulsion while reducing leg fatigue during long or repeated dives.
– The 30° blade angle combined with the Hardtip™ design ensures effective performance even at greater depths.
– Suitable for professional divers or those looking to elevate their freediving and spearfishing performance.
Conclusion
If you are looking for powerful, high-performance carbon fin blades to elevate your freediving or spearfishing, Alchemy V3-30 are well worth considering. With a 15-layer carbon construction, optimized blade angle, and refined hydrodynamic design, these blades are built for efficient and durable diving.
