The Cetma Mantra CWT Competition carbon fiber blades in various colors are engineered for peak performance in constant weight freediving. Developed in collaboration with world champion Michele Giurgola, these blades feature Cetma's innovative Dynamic Resonance System (DRS), tuning the blade to resonate with kicking frequency for maximum thrust with reduced effort. The 100% IM7 carbon fibre, processed with 3D-Tech, ensures a void-free, high-strength blade. The stiffness distribution is meticulously designed using Finite Element Method (FEM) analysis to minimize fatigue on calf and tibia muscles, crucial for deep dives. A reduced blade angle of 27° helps athletes maintain perfect trim during both descent and ascent on the line. While optimized for CWT, they also offer good performance for dynamic apnea, especially for those preferring longer blades. These blades feature Cetma's Hi-Efficiency water rails for enhanced stability and water channeling. Footpockets are not included.
