The Cetma Mantra CWT Competition carbon fiber blades, featuring a sleek black design, are meticulously engineered for elite constant weight freediving. Born from a collaboration with world champion Michele Giurgola, these blades incorporate Cetma's groundbreaking Dynamic Resonance System (DRS). This system tunes the blade to the diver's kicking frequency, maximizing thrust while minimizing energy expenditure. Constructed from 100% IM7 carbon fibre using the advanced 3D-Tech process, the blades are void-free and exceptionally strong. The stiffness distribution, refined through Finite Element Method (FEM) analysis, is specifically designed to reduce strain on the calf and tibia muscles, critical for deep dives. A carefully chosen 27° blade angle aids athletes in maintaining perfect horizontal trim during both descent and ascent phases on the competition line. While primarily for CWT, they also perform well in dynamic apnea, suiting freedivers who prefer a longer blade. Equipped with Cetma’s Hi-Efficiency water rails for stability. Footpockets are sold separately.
