Fins with world-class
efficiency, making the most of your energy.
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 and it has been
the undisputed leader in the plastic fin market. Now,
ten years later, we are moving to the next development
stage. The next generation 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 a light
kick in the SF-8 model. A fin testing robot was used to
do a computer analysis of the propulsion (speed) and
electrical load when kicking. Tests were also run using
real divers in a water circulating pool. After repeating
these tests many times, 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 efficient transmission of energy ensures that
body fatigue and air consumption is minimized.
