Technisub Idea 3

IDEA3 is designed to achieve maximum benefit from the down stroke while offering the minimum resistance during the up stroke. It has been ranked, by some of the best diving magazines, in first position for the ratio “effort demanded / thrust received”. A unique multi-patented moulding technology has been developed to inject together 3 materials of different flexibility, for different functions:
- a soft, comfortable thermoplastic rubber for the foot pocket
- a soft, elastic technopolymer for the pre-deformed central section of the blade featuring a variable geometry
- a stronger and more resilient material for the supporting structure of the fin.

The IDEA3`s variable geometry, gives a
concave shape during the down-stroke,
producing a ``scoop`` effect. The water is trapped and channelled, maximising
propulsive thrust and preventing lateral side-slipping of the fin.
During the negative recovery action of the up-stroke the end of the blade, which is very flexible, is free to bend and so reduces its surface and the effort required.
