A highly versatile fin, the SlingShot allows divers to frequent a wide range of conditions, from diving in cold water with thick exposure suits and heavier gear to cruising warm water reefs with minimal equipment. Silicone Power Bands and a Three-Speed Gear Shift allow divers to dial in the best speed-to-effort ratio and match the SlingShot to changing dive conditions and their own leg strength.A semi-rigid, technopolymer blade has an excellent spring effect for maximized thrustBlade ribs are made of two different elastomeric compounds and provide precise flex controlSilicone Power Bands are loaded with energy during the down stroke, which they release prior to the upstroke for a power boost on every kickThree-Speed Gear Shift allows divers to dial in Power Band resistance for their body type or changing diving conditions, and adjustments can be made while wearing the finA Mid-foot Flex Joint is used to attach the blade to the side of the foot pocket. This maximizes energy transfer from the leg and provides the power of a blade 30% longerThe Mid-foot Flex Joint provides a greater range of blade motion, up to five times that of a standard paddle fin, and reduces strain on the ankle and toesAnti-slip rubber pads on the bottom of the foot pocket provide traction for moving around on boat decksStreamlined foot pocket provides an ergonomic fit for excellent energy transfer and accommodates a wide range of dive bootsESBS (Ergonomic Strap and Buckle System) uses a press-to-release button that is easily operated, even while wearing thick glovesRubber heel straps are made with anti-aging compounds and have large finger loops at each end and in the middle for easy donning, even when wearing heavy glovesSmall, regular and Large/X-largeTravel FriendlyPower Technology
