Product Code: SF6 Price: Check Latest TUSA's Imprex Tri-Ex Scuba or Snorkel Fin Fins with world-class efficiency, making the most of your energy In 1993 TUSA introduced the SF-7700 (Imprex Fin) to the market. This fin achieves strong propulsion by combining two different materials to create an efficient water channeling action. Since it first went on sale, over 600,000 divers have used it worldwide. The Imprex fin has been the undisputed leader in the plastic fin market. Now, ten years later, it is moving to the next development stage. The next gerneration TUSA Imprex Tri-Ex fin utilizes three different materials. First is the side rib (hard material), efficiently converting the energy of a kick into propelling power. Second is the blade (medium-hard material), increasing the efficiency of the water channel. Third is the soft pocket (soft material), enhancing the fitting comfort of the boots. The designers expanded the blade angle theory that had produced a strong propulsion force with only one light kick in the SF-8 model. A fin testing robot was used to analyze on a computer the propulsion (speed) and the electrical load when kicking. Tests were also run using real divers in a water circulating pool. These tests were repeated many times, the result being that the blade angle was set at 20 degrees, the most comfortable for the diver. A smooth shape was also created, with no level differences between the foot pocket and the blade. This means that compared with conventional products, less initial load (energy) is required when first starting to kick. The excellent fit and non-wasteful transmission of energy ensures that body fatigue and air consumption is minimized. Uses TUSA's unique Advanced Multi-Flex Blade, made from 3 different materials Most of the foot pocket is covered by soft material, enhancing the fit and making it easier to put on or take off.
