| 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
principal design by Nature's Wing's developed this
unique fin. The split fin is outfitted with an
innovative, angled concept. Using the human anatomy as a
reference, the SF-8 fin has been designed to provide
maximum propulsion with minimum exertion. |
| When using a standard
flat fin, propulsion is inhibited solely by
fault of design. When the leg is completely
extended, there remains an angle of 27 degrees
between the heel of the foot and the calf of the
leg, as shown in the diagram. This 27-degree
angle causes 10% of the propulsion that is
produced by the kicking motion to be lost.
Because the fin is angled below the body during
the kick phase, the body is pushed up and
forward, instead of straight ahead. |
| With the SF-8 fin, that
27-degree angle has been incorporated into the
fin. This means that when the leg is fully
extended, even though the angle exists between
the foot and the calf, the fin ends up parallel
to the leg. This means that 100% of the energy
expended during the kicking phase is directed
toward the propulsion of the diver. |
