The new Sigalsub Tsunami carbon fins represent the highest possible material quality. T700 12K Prepreg carbon virtually eliminates any defects and keeps performance constant. The durability of the blades is guaranteed and performance is maximized.

Offered in Super Soft, Soft, Medium and Hard stiffness options, and with a 23° angle between foot pocket and blade, our new Tsunami fins are designed for both spearfishers and pure freedivers. The thrust is excellent in all conditions, allowing easy ascent even from the deepest dives.

The Sigalsub foot pocket is made of thermo-rubber with differentiated thicknesses. This ensures a soft and comfortable fit where needed, while being reinforced in the areas responsible for transferring power from the foot to the blade, such as the instep and the sole.

Thrust, progressiveness and kick control are optimal, while still avoiding leg fatigue. In this way, the Sigalsub Tsunami excel both in deep dives and in pool freediving.

Finally, the foot pocket–blade connection is made with a single Allen screw which, thanks also to the ultra-short rails, allows for quick assembly. At the same time, the threaded nut embedded in a plastic plate makes the blade–foot pocket connection safe and long-lasting.
