SF-8 X-PERT ZOOM |
Model#: SF-8 |
|
Unlike traditional fins which create propulsion only through repulsive force, the SF-8 attains propulsion by creating
a pressure differential in the water flow. 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.
The SF-8 X-Pert Zoom fin's eye-catching design is causing quite a stir in the diving world! TUSA's production technology
combined with Nature's Wing's principal design developed this unique fin. The split fin is outfitted with an innovative,
angled concept. Using the human anatomy as reference, the SF-8 fin has been designed to provide maximum propulsion, with
minimal exertion.
Features:

27 Tech Reasons
When using the standard, traditional blade fin, with the leg completely extended, there remains an angle of 27 degrees 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, instead of straight ahead. With
the SF-8 fin, that 27 degree angle has been designed into the fin so the fin is parallel to the leg. This means that 100% of the energy expended during the kick
phase is directed toward the propulsion of the diver. TUSA developed a robot that can replicate the motions of a human being. The robot is able to mimic the human
under kick-bending at the ankle, knee and hip in one fluid motion. Using this robotic science, TUSA has been able to analyze the performance of the fins under
several conditions. The robot is able to swim, through the water using kick variations, such as a large scissor kick with a slow repetition and vice versa. Using the
latest technology, this robot measures the energy expended during the kick and the propulsive force that is created using that energy. 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.
