TUSA Fin's Technology
TUSA’s advanced split fins employ Propeller-FinTM Technology, which delivers ultra-high performance with a low amplitude rapid flutter kick. As the fin moves through the water its two wing-shaped surfaces create lift and forward propulsion like a propeller. Any water traveling over the top of the blade is funneled into and out of the split between the blades. Efficiency is increased while drag and effort is reduced.
Angled Blade Design (A.B.D.)
TUSA’s Angled Blade Design is employed on the SF-15, SF-8 and SF-6 fins. A standard flat fin inhibits propulsion solely by fault of design. An angle between the heel of the foot and the calf of the leg remains when the leg is extended to kick. This angle causes 10% of the propulsion to be lost. The Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.
H.B.S. (Hybrid Blade System)
The patented Hybrid Blade System offers unparalleled propulsion, efficiency and power transfer in a multi-compound design. The H.B.S. is composed of incredibly stiff urethane side rails and an ultra-responsive membrane blade giving unlimited kicking potential.
EZ Strap and Buckle System
TUSA's EZ strap and Buckle System allows fins to be quickly and easily adjusted with minimal effort. Adjustment can be made while the fins are worn, allowing for a precise fit and ease of removal when necessary.
