Freediving and Spearfishing Fins Bm30 Black-Blue 41-42 Seac 71-56N-41-42
Description:
The SEAC BM-30 fins are designed for freediving and spearfishing, combining advanced construction with a streamlined shape for efficient underwater propulsion. They feature Seac’s FRC™ technology, a Fully Responsive Compound developed to deliver performance similar to carbon and glass fiber while improving durability and flexibility. The blade is made with two different materials: a stiffer section on the sole for stability and a softer upper section for greater comfort during longer sessions. Its 30° angled design helps support natural ankle positioning and makes surface finning easier and more comfortable. Small stabilizing fins at the end of the blade help reduce sideways drift without affecting power or blade flex. The fins are engineered to resist breakage and permanent deformation, even in low temperatures. With their hydrodynamic and ergonomic design, the BM-30 aims to provide responsive, efficient finning in the water. They are 100% Made in Italy in Seacsub’s solar-powered factory.
