High quality Lab-Made Mantra carbon fins, featuring the revolutionary Dynamic Resonance System  from Cetma Composites.

The Mantra blades are tuned to specific natural frequencies which allow the blades to resonate with the freedivers kicks underwater, providing outrageously efficient energy conversion with absolutely minimal effort. These fins were developed and tested in collaboration with Michele Giurgola, who's signature is also featured on blades.

The Mantra blades are designed with an increased blade angle of 33 degrees for easier surface swimming and variable blade rigidity (3-D Design) which maximizes energy conversion and propulsion efficiency, supplying the freediver with unmatched power and performance.

Variable width blade rails allow higher stability and better handling underwater. Available in green and magenta.

These high end carbon fins are the result of Cetma Composites engineering approach to the development and manufacturing process of freediving fins, coupled with years of material studies and experience in the design of composite materials for the aerospace and automotive industries.

Blade Dimensions: ~ 87 x 19.5 cm / 34.3 x 7.7 inch
