The Tusa Tri-Ex open heel dive fin provides more speed and power than traditional diving fins by combining three materials to create a fin blade with the optimum amount of flex and stiffness. The Tusa SF-6 Dive fin has a generous foot pocket for maximum comfort and power transfer from the diver to the blade. The unique combination of advanced engineering creates scuba fins with good low end torque, as well as the power needed for currents and other forms of advanced diving.
