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 the phenomenon of resonance to optimize thrust transmission and responsiveness. This advanced design improves the smoothness and efficiency of the kick during freediving and spearfishing activities.\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, to increase 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 kicking style and the required level of stiffness.\u003c\/li\u003e\n\u003cli\u003eSizes: 39\/40, 41\/42, 43\/44, 45\/46, to fit different foot sizes perfectly.\u003c\/li\u003e\n\u003cli\u003eBlade dimensions: 742 x 195 mm, sized to ensure 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":56925964337497,"sku":"MNXGDGD + SWBK39","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 39-40","offer_id":56925964370265,"sku":"MNSGDGD + SWBK39","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 39-40","offer_id":56925964403033,"sku":"MNMGDGD + SWBK39","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"20 - Super Soft \/ 41-42","offer_id":56925964435801,"sku":"MNXGDGD + SWBK41","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 41-42","offer_id":56925964468569,"sku":"MNSGDGD+ SWBK41","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 41-42","offer_id":56925964501337,"sku":"MNMGDGD + SWBK41","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"20 - Super Soft \/ 43-44","offer_id":56925964534105,"sku":"MNXGDGD + SWBK43","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 43-44","offer_id":56925964566873,"sku":"MNSGDGD+ SWBK43","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 43-44","offer_id":56925964599641,"sku":"MNMGDGD + SWBK43","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"20 - Super Soft \/ 45-46","offer_id":56925964632409,"sku":"MNXGDGD + SWBK45","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"25 - Soft \/ 45-46","offer_id":56925964665177,"sku":"MNSGDGD+ SWBK45","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 45-46","offer_id":56925964697945,"sku":"MNMGDGD + SWBK45","price":450.0,"currency_code":"EUR","in_stock":true},{"title":"30 - Medium \/ 47-48","offer_id":56925964730713,"sku":"MNMGDGD + SWBK47","price":450.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/6732\/1945\/files\/Pinne_Mantra_-_Oro.png?v=1782072527","url":"https:\/\/deepbluesub.com\/en\/products\/cetma-composites-mantra-gold-fins","provider":"DEEP BLUE - Freediving \u0026 Spearfishing","version":"1.0","type":"link"}
