Cetma Prana Carbon Composite Freediving Fin Blades

A hybrid carbon and fiberglass freediving fin giving you the best of both worlds, efficient propulsion and lightweight construction with high strength and durability. A great high performance carbon fin that doesn’t break the bank.

Prana models are medium length fins; they offer a progressive blade sensation and are ideal for fishing in medium and shallow waters. Ideal blade for all fishermen who want a high-performance and easy-to-use fin. The high inclination facilitates swimming when moving on the surface.

Why Choose Cetma?

CETMA fins are produced with ZDF Excellence, a proprietary aerospace-derived manufacturing technology that guarantees extremely high structural quality and consistency.
The production process uses CETMA’s exclusive OOT, Technology (Out Of Autoclave process), a proprietary composite manufacturing method developed by CETMA Composites. This technology allows precise control of carbon fiber orientation, resin distribution and structural integrity, achieving a perfect carbon fiber / resin ratio with zero defects.
This process ensures:
• Maximum structural reliability
• Consistent flex characteristics
• High durability under load
• Optimal energy transfer during finning
All fins are 100% Made in Italy, designed and manufactured entirely by CETMA Composites. CETMA engineers also developed the DRS – Dynamic Resonance System, which allows the blade to enter natural resonance during the kicking cycle. The blade continues part of its movement naturally, reducing muscular fatigue and increasing propulsion efficiency.
For this reason, many top freediving athletes and competition record holders use CETMA fins.
All fins feature variable-height side rails, positioned only where needed to correctly channel water flow while allowing the blade to flex freely and react instantly.
