TUSA X-Pert Zoom Z3 Open Heel Split Fins

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 X-Pert 3Z 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 X-Pert Zoom Z3 The Fin for Divers".

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 X-Pert Z3 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.

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. Any water traveling over the top of the blade is funneled into and out of the split between the blades. Efficiency is increased while drag and effort is reduced. Fins are equipped with TUSA's high quality stainless-steel spring straps with TUSA's EZ buckle system. The spring straps do not need to be adjusted for size and easily slip over the heel securely when donning and doffing the fins. The EZ buckle system has squeeze-style" side-release buckles allowing quick and easy adjustments with minimal effort. Adjustment can be made while the fins are worn, allowing for a precise fit and ease of removal when necessary. Spring straps are also depth compensating and automatically adjust for wet suit boot compression at depth. Straps are equipped with a comfortable rubber heel grip with a large finger loop for an easy fit. The TUSA X-Pert Zoom Z3 Fins are available in multiple sizes and colors. Fin measure 22.8" to 25.7" (57.8 cm to 65.3 cm) depending on size.
