Reviews about Tusa Imprex TRI-EX
Tusa Imprex TRI-EX:
The SF-6 Imprex Tri-Ex fin features TUSA’s Advanced Multi-Flex Blade, made from 3 different materials which reduces diver fatigue and air consumption for fast and powerful propulsion from a traditional blade fin.
In 1993 TUSA introduced the SF-7700 (IMPREX) to the market.
This fin achieves strong propulsion by combining two different materials to create efficient water channeling action.
The IMPREX fin has been the undisputed leader in the plastic fin market.
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 foot pocket (soft material), enhancing the fitting comfort and transferring power to the ribs and blade.
The designers expanded the blade angle theory of the SF-8 X-Pert Zoom that had produced a strong propulsion force with only a light kick.
A fin testing robot was used to analyze the propulsion (speed) and the electrical load when kicking.
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 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.
