Cetma Edge Pure Carbon Freediving Fin Blades

A premium pure carbon freediving fin giving you maximum power and efficiency.

Trusted by world class spearfishers and competition freedivers all over the globe, the Edge carbon fins set the benchmark for high performance and quality.

What Cetma have to say about these fins:

Fins with a reactive and powerful character, they were created for deep fishing.
For those who want to feel the immediate detachment from the bottom.
In the Xsoft and Soft stiffnesses they can also be used in deep freediving.
The first fins developed by CETMA COMPOSITES, the Edge, remain unbeatable in the detachment from the bottom and are the most suitable choice for those who prefer extremely reactive and powerful fins.
Much loved by fishermen from all over the world, in the Xsoft and Soft stiffnesses they can also be used in deep freediving.

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.
