| | SF-6 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. | | | |  | | | | SF-8 X-PERT ZOOM The SF-8 X-Pert Zoom split fin is unlike traditional fins which create propulsion only through repulsive force, the SF-8 attains propulsion by creating a pressure differential in the water flow using Propeller-fin technology. |  | | SF-77/88/9900 IMPREX The Imprex fin blade is made of different materials. The outside ribs are made from stiff material and between the ribs is softer, more pliable material for effective water channeling. This combination of materials allows for even and stable channeling in any condition. |
