The tapered profile of the blade is not just aesthetic: it is the result of a precise technical choice. The variable thickness allows flex to be optimally distributed along the entire blade, ensuring high finning performance without sacrificing maneuverability or effective length.

Technical Features

• Material: high-quality elastomer, durable and high-performance
• Tapered profile with variable thickness for maximum hydrodynamic efficiency
• V-tip for a more stable kick and to eliminate lateral water slippage
• Large load-bearing surface for powerful thrust with every fin stroke

Dimensional Specifications

• Blade width: 19.0 cm
• Blade length: 71.3 cm (713 mm)

Why Choose the X-Wing Pro

The X-Wing Pro elastomer blade is the ideal choice for those who want a responsive, stable, high-performance fin. The V-tip reduces lateral water dispersion, translating every movement into direct, precise thrust. Ideal for freediving and spearfishing sessions where agility and control make the difference.

Blades PULSE - Cetma Composites

The PULSE carbon blades by Cetma Composites are a true revolution in the world of spearfishing and water training. Designed and manufactured 100% Made in Italy, the PULSE introduce the Hyperbolic Curve: an exclusive geometry that delivers maximum thrust with minimal effort, redefining the concept of responsiveness for high-performance carbon blades.

Technology and Materials

The PULSE blades are built with a selection of aerospace-derived composite materials, chosen to ensure maximum hydrodynamic efficiency and the highest structural reliability in all conditions of use.

• 100% HM (High Modulus) and HR (High Resistance) Carbon: the optimal combination of stiffness and toughness for a blade that is responsive, reactive, and virtually indestructible.
• Hot Melt Pre-preg: the composite material is impregnated with hot-melt systems using high-performance resin, ensuring a consistent and optimal fiber/resin ratio across the entire blade surface.
• OOT Technology – Out-of-Autoclave Technology: an exclusive Cetma Composites production process that achieves the same quality standards as the aerospace industry without the use of an autoclave, optimizing control over the composite curing process.

ZDF Excellence – Zero Defects

The PULSE blades are produced with Cetma Composites’ proprietary ZDF (Zero Defects) technology. This aerospace-derived production standard ensures a component with 0% internal voids, free from structural defects and with a perfectly consistent fiber/resin ratio throughout the blade. The result is a blade that maintains its original mechanical characteristics over time, with no performance degradation.

FEM-Optimized Design

The geometry of the PULSE blades is the result of advanced design using finite element analysis (FEM – Finite Element Method). The structural simulation software used by Cetma Composites ensures optimal stiffness distribution, in order to reproduce a blade deformation profile that maximizes hydrodynamic efficiency during finning, both vertically and horizontally.

The Hyperbolic Revolution

The defining feature of the PULSE blades is the Hyperbolic Curve: a patented geometry that sets these blades apart from any other product currently on the market. Thanks to this shape, the blade delivers a unique biomechanical response, with instant responsiveness and powerful thrust from the very first kick. Ideal for spearfishing and intensive training sessions, the PULSE are designed for those seeking maximum performance without compromise.

Main Features

• Exclusive Hyperbolic Curve: maximum thrust with minimal effort
• 100% HM + HR Carbon: high elastic modulus and high mechanical strength
• Hot Melt Pre-preg: hot-melt impregnation for superior composite quality
• OOT Technology (Out-of-Autoclave): exclusive Cetma Composites aerospace production process
• ZDF Excellence – Zero Defects: 0% voids, defects, and structural discontinuities
• FEM Design: advanced finite element design for optimal hydrodynamic efficiency
• 100% Made in Italy
• Ideal for spearfishing and training
