The new Sigalsub Tsunami carbon fins represent the highest possible quality in materials. T700 12K Prepreg Carbon virtually eliminates defects and maintains consistent performance. Blade durability is guaranteed and performance is maximized.
Available in Super Soft, Soft, Medium, and Hard hardnesses and with a 23° angle between the foot pocket and blade, our new Tsunami fins are designed for both spearfishing and freediving. Propulsion is excellent in all conditions, allowing for easy resurfacing from deep dives.
Propulsion, progression, and control of the fin stroke are optimal while also not tiring the legs. This makes the Sigalsub Tsunami excellent for both deep dives and freediving in the pool.
Finally, the foot pocket-blade connection is made with a single Allen screw which, combined with the ultra-short stringers, allows for quick connection. At the same time, the threaded nut embedded in a plastic plate makes the blade-shoe connection safe and long-lasting.
