Made entirely from \u003cstrong\u003e100% Pre-preg carbon\u003c\/strong\u003e, 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.\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 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.\u003c\/p\u003e\n\u003ch3\u003eComponents and Comfort\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssembly with \u003cstrong\u003eS-Wing\u003c\/strong\u003e foot pockets without side rails, increasing comfort and freedom of movement.\u003c\/li\u003e\n\u003cli\u003eConstant-section water rails with a height of 10 mm, designed to improve hydrodynamic hold and stability in the water.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAvailable Variants\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStiffnesses: 20 super soft, 25 soft, 30 medium, allowing a calibrated choice based on kick style and the required stiffness level.\u003c\/li\u003e\n\u003cli\u003eSizes: 39\/40, 41\/42, 43\/44, 45\/46, to perfectly fit different foot sizes.\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 \/ 39-40","offer_id":58069246214489,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 39-40","offer_id":58069246247257,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 39-40","offer_id":58069246280025,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"20 - Super Soft \/ 41-42","offer_id":58069246312793,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 41-42","offer_id":58069246345561,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 41-42","offer_id":58069246378329,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"20 - Super Soft \/ 43-44","offer_id":58069246411097,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 43-44","offer_id":58069246443865,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 43-44","offer_id":58069246476633,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"20 - Super Soft \/ 45-46","offer_id":58069246509401,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 45-46","offer_id":58069246542169,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 45-46","offer_id":58069246574937,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 47-48","offer_id":58069246607705,"sku":null,"price":450.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/6732\/1945\/files\/pinne-cetma-mantra-magenta.png?v=1778867374","url":"https:\/\/deepbluesub.com\/en\/products\/magenta-mantra-fins-cetma-composites","provider":"DEEP BLUE - Freediving \u0026 Spearfishing","version":"1.0","type":"link"}
