Their design supports efficient propulsion during surface swimming, controlled underwater movement, and ascents, with reduced vibration during smaller fin kicks.\u003c\/p\u003e\u003ch6\u003eCarbon Fiber Construction and Performance\u003c\/h6\u003e\u003cp\u003eThe blades incorporate Variable Parabolic Stiffness (VPS), a multilayer carbon arrangement designed to produce a responsive flex and recovery cycle. As the blade bends under kicking force, its structure allows it to return toward its original shape, supporting propulsion while reducing unnecessary effort.\u003c\/p\u003e\u003cp\u003eThe quadraxial construction positions carbon fibers along four different orientations to improve resistance to torsional twisting. This reinforcement helps maintain controlled blade movement during directional changes and subtle kicks when approaching fish.\u003c\/p\u003e\u003ch6\u003eFoot Pocket Compatibility and Installation\u003c\/h6\u003e\u003cp\u003eThese are replacement fin blades only; foot pockets must be purchased separately. Installation requires a mounting configuration compatible with the intended foot pockets. Select the appropriate drilling option before ordering, particularly when fitting the blades to existing foot pockets.\u003c\/p\u003e\u003cp\u003eBlade stiffness should be selected according to body weight, leg strength, and kicking technique. Proper stiffness allows the blade to flex and recover effectively throughout the kick cycle, while an excessively stiff blade may increase fatigue and reduce propulsion efficiency.\u003c\/p\u003e\u003cp\u003eDeep Apnea provides a three-year limited warranty against qualifying blade defects and breakage during normal freediving use, subject to registration, approved foot pocket installation, and manufacturer warranty conditions.\u003c\/p\u003e","brand":"Deep Apnea","offers":[{"title":"Soft \/ No Holes","offer_id":50501098635456,"sku":"CUB-777-JUM","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Soft \/ Drill for Beauchat","offer_id":50501098668224,"sku":"ZZY-582-XGY","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Soft \/ Drill for Cressi","offer_id":50501098700992,"sku":"RVJ-242-MPY","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Soft \/ Drill for Hammerhead","offer_id":50501098733760,"sku":"VNQ-614-KNJ","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Medium \/ No Holes","offer_id":50501098766528,"sku":"VGP-465-VUD","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Medium \/ Drill for Beauchat","offer_id":50501098799296,"sku":"RJM-991-VKO","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Medium \/ Drill for Cressi","offer_id":50501098832064,"sku":"BYM-565-CEY","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Medium \/ Drill for Hammerhead","offer_id":50501098864832,"sku":"MXU-839-CZU","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Hard \/ No Holes","offer_id":50501098897600,"sku":"IZC-780-DYC","price":549.0,"currency_code":"USD","in_stock":false},{"title":"Hard \/ Drill for Beauchat","offer_id":50501098930368,"sku":"HSN-330-RBH","price":549.0,"currency_code":"USD","in_stock":false},{"title":"Hard \/ Drill for Cressi","offer_id":50501098963136,"sku":"RBR-967-XKA","price":549.0,"currency_code":"USD","in_stock":false},{"title":"Hard \/ Drill for Hammerhead","offer_id":50501098995904,"sku":"DNG-643-JNU","price":549.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/7394\/9888\/files\/imgi_117_EliteCompressed3-nobg-optimized.webp?v=1792030743","url":"https:\/\/www.foreveryoungoutfitters.com\/products\/deep-apnea-elite-85cm-carbon-fiber-fin-blades","provider":"Forever Young Outfitters","version":"1.0","type":"link"}
