Pulse Fins

Fins PULSE - Cetma Composites

The PULSE Fins by Cetma Composites represent a true revolution in the world of spearfishing and training fins. Designed and manufactured 100% in Italy, the PULSE introduce Hyperbolic Curvature — an exclusive geometry that delivers maximum thrust with minimal effort, redefining the standards of responsiveness and propulsion for the most demanding spearfishers and freedivers.

The Hyperbolic Revolution

The PULSE blade design stands out for its proprietary hyperbolic curvature, engineered to optimize energy transfer with every kick. This advanced geometry ensures immediate response and superior propulsion, making it the ideal choice for both high-performance spearfishing and intensive training sessions.

Aerospace Technology: ZDF and OOT

• ZDF Excellence — Zero Defects: proprietary aerospace technology by Cetma Composites that guarantees a blade free from structural imperfections, with a constant and controlled fiber/resin ratio across the entire surface.
• OOT — Out-of-Autoclave Technology: exclusive production process developed by Cetma Composites that achieves the lamination quality and density typical of aerospace components without using a traditional autoclave, ensuring extreme lightness and exceptional strength.

High-Performance Materials

• HM Carbon (High Modulus): ultra-high-stiffness fibers for a precise, powerful response throughout every finning cycle.
• HR Carbon (High Resistance): high-toughness fibers to ensure structural strength and long-lasting durability even under the most demanding use conditions.
• Hot Melt Pre-preg: hot impregnation system that ensures optimal resin distribution within the blade structure, eliminating voids and discontinuities.

FEM Design: Engineering at the Service of Performance

The geometry of the PULSE fins is optimized through finite element analysis (FEM — Finite Element Method), an advanced design methodology derived from aerospace and structural engineering. This approach allows stiffness to be precisely distributed along the entire blade, creating an optimal deformation profile that maximizes hydrodynamic efficiency and minimizes the user’s muscular fatigue.

100% Made in Italy

The PULSE Fins Cetma Composites are entirely designed and manufactured in Italy, reflecting the manufacturing excellence and technological know-how of Cetma Composites, a global leader in the production of carbon equipment for freediving and spearfishing.
