Cetma Mantra Blades - Carbon
The Mantra blades are the flagship model from Cetma Composites, specifically designed for freedivers and spearfishers who demand high-level technical equipment. Made entirely from 100% Pre-preg carbon, the blades are built using an exclusive hot-melt impregnation technology with tetra-functional resin, applied under high pressure, high temperature, and vacuum conditions. This process ensures a defect-free blade, with a consistent fiber/resin ratio across the entire surface.
Design and Technical Features
The engineered distribution of stiffness and mass in the blade allows its natural frequency to be tuned to the finning frequency range, leveraging resonance to optimize thrust transfer and responsiveness. This advanced design improves the fluidity and efficiency of the fin stroke during freediving and spearfishing.
Constant-section water rails with a height of 10 mm, designed to improve hydrodynamic grip and stability in the water.
Available Variants
- Stiffnesses: 20 super soft, 25 soft, 30 medium, allowing a calibrated choice based on finning style and the required stiffness level.
- Blade dimensions: 742 x 195 mm, sized to ensure an effective balance between thrust and maneuverability.
- Available graphics: gold, white, magenta.
