Made entirely from \u003cstrong\u003e100% pre-preg carbon\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003ch3\u003eDesign and Technical Features\u003c\/h3\u003e\n\u003cp\u003eThe 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 transmission and responsiveness. This advanced design improves the smoothness and efficiency of the kick during freediving and spearfishing.\u003c\/p\u003e\n\u003cp\u003eConstant-section water rails with a height of 10 mm, designed to improve hydrodynamic tracking and stability in the water.\u003c\/p\u003e\n\u003ch3\u003eAvailable Variants\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStiffness options: 20 super soft, 25 soft, 30 medium, allowing a calibrated choice based on kick style and required stiffness level.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBlade dimensions: 742 x 195 mm, sized to provide an effective balance between thrust and maneuverability.\u003c\/li\u003e\n\u003cli\u003eAvailable graphics: gold, white, magenta.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cetma","offers":[{"title":"20 - Super Soft","offer_id":58070174007641,"sku":"MNXWHWH","price":365.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft","offer_id":58070174040409,"sku":"MNSWHWH","price":365.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium","offer_id":58070174073177,"sku":"MNMWHWH","price":365.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/6732\/1945\/files\/palecetmamantrabinache.png?v=1778877642","url":"https:\/\/deepbluesub.com\/en\/products\/white-mantra-blades-cetma-composites","provider":"DEEP BLUE - Freediving \u0026 Spearfishing","version":"1.0","type":"link"}
