bio-fin pro XT
The higher hardness type for special use.
Feel to foot the reaction force at the time of fin kick, instantaneous force emphasis high hardness model
Powered by natural rubber.
Natural rubber is the best for split-type fins.
For the propulsive efficiency, it is important to open the slit widely and smoothly in the water when diver strokes the fins.
The bio-fin has astonishingly flexibility and elasticity with natural rubber.
And it spreads smoothly with right force.
Furthermore it keeps good efficiency for long time caused with its anti-decline individuality.
High hardness compound version of bio-fin pro
Using the compound that is up about 15% hardness compared with bio fin professional , it especially improves the kick feeling and instantaneous force against the foot .
We recommend it for those who have a sense of discomfort at the time of transfer from a conventional paddle type fin, and for those that need to swim in a particularly swift current .
Propulsive efficiency for the overall input power will fall slightly from bio-fin pro , but the difference is very slight. It is the high-efficiency fin of the different dimension in comparison with general paddle fins. (Comparison with our measured value)
