Mantra Fins - Magenta

100% Pre-preg Carbon Mantra Fins for Freediving and Spearfishing

The Mantra fins 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 with an exclusive hot-melt impregnation technology using 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 fin-kick frequency range, leveraging the resonance effect to optimize thrust transmission and responsiveness. This advanced design improves the smoothness and efficiency of the kick during freediving and spearfishing.

Components and Comfort

• Assembly with S-Wing foot pockets without side rails, increasing comfort and freedom of movement.
• Constant-section water rails with a height of 10 mm, designed to improve hydrodynamic hold and stability in the water.

Available Variants

• Stiffnesses: 20 super soft, 25 soft, 30 medium, allowing a calibrated choice based on kick style and the required stiffness level.
• Sizes: 39/40, 41/42, 43/44, 45/46, to perfectly fit different foot sizes.
• Blade dimensions: 742 x 195 mm, sized to provide an effective balance between thrust and maneuverability.
• Available graphics: gold, white, magenta.
