Details More Information Product Attachment Related Spare part Fins Open Heel Tusa X-pert z-3 Zoom SF-15 Over 5 years of research and development brought the highly regarded and best-selling SF-8 X-Pert Zoom split fin to market in 2003. TUSA redefines the fin market again with the introduction of the SF-15 X-Pert Zoom Z3. The SF-15 further improves upon the performance, features and design of the SF-8 with the incorporation of 3 materials, 10% longer blade length, enhanced propeller-fin technology, reinforced blade rails and optimized blade scoops. These new features along with TUSA's patented 27° Angled Blade Design and EZ strap buckle system make the SF-15 THE fin for divers. TUSA’s Angled Blade Design: When using the standard traditional blade fin, with the leg completely extended, there remains an angle of 27° between the heel and the foot and the calf of the leg, causing a 10% loss of propulsion. Because the fin is angled below the body, during the kick phase, the body is pushed forward and down, instead of straight ahead. With the SF-15 fin, that 27° angle has been designed into the fin. This means that 100% of the energy expended during the kick phase is directed toward the propulsion of the diver. To achieve maximum performance from this fin, use a small bent-knee kick with a light rhythm. This creates less strain on the leg muscles compared with traditional fins, reducing the diver’s fatigue and subsequent air consumption. Features : Three material design for increased performance compared to standard split fins Patented 27° Angled Blade Design Enhanced propeller-fin technology optimizes efficiency Multi-compound foot pocket increases power transfer to the fin blade Reinforced side-rails decrease blade separation increasing stability and kick-style versatility Optimized blade scoops increase water channeling Innovative hydrofoil design that produces forward motion (propulsion) with less effort 10% longer blade than SF-8 for enhanced propeller effect TUSA patented EZ Strap and buckle system Color : Black Blue Yellow Technology : Angle blade design : The Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle. Ez strap and buckle system : TUSA’s EZ strap and Buckle System allows fins to be quickly and easily adjusted with minimal effort. Adjustment can be made while the fins are worn, allowing for a precise fit and ease of removal when necessary. Propeller technology : TUSA’s advanced split fins employ Propeller-Fin Technology, which delivers ultra-high performance with a low amplitude rapid flutter kick. As the fin moves through the water its two wing-shaped surfaces create lift and forward propulsion like a propeller. Efficiency is increased while drag and effort is reduced.
