TUSA SF-15 X-Pert Zoom Z3 Fins

In 2003, after over 5 years of research and development, TUSA launched the highly acclaimed and top-selling SF-8 X-Pert Zoom split fin. Then in 2009, TUSA once again redefined the fin market by introducing the SF-15 X-Pert Zoom Z3. Building upon the success of the SF-8, the SF-15 offers improved performance, features, and design, including the use of 3 materials, 10% longer blade length, enhanced propeller-fin technology, reinforced blade rails, and optimized blade scoops.

The SF-15 also incorporates TUSA's patented 27 degree Angled Blade Design and EZ strap buckle system, establishing it as the ultimate fin for divers. The Angled Blade Design (A.B.D.) is a revolutionary feature that maximizes propulsion. Unlike traditional blade fins, with the SF-15, the 27 degree angle between the heel, foot and calf is built into the design, ensuring that 100% of the energy expended during the kick phase is directed towards propelling the diver forward, rather than causing any loss of propulsion.

TUSA's dedication to innovation is demonstrated through the use of a specialized robot that replicates the kick-cycle and movement of a human leg. This high-tech robot is able to accurately mimic human motion and collects precise data on the performance of the fins under various conditions. By simulating different swimming techniques and kick variations, such as a large scissor kick with slow repetition, the robot measures the energy expended during the kick and the resulting propulsive force to optimize the fin's performance.

The SF-15's three material design enhances its performance compared to standard split fins, while the patented 27 degree Angled Blade Design maximizes propulsion efficiency. Additionally, the enhanced propeller-fin technology optimizes power transfer to the fin blade, and the reinforced side-rails increase stability and kick-style versatility for divers. These advanced features make the SF-15 X-Pert Zoom Z3 an exceptional choice for divers seeking top-notch performance and efficiency in their fins.
